74-98: Persistlast_errorfor all MCPComposer startup failures, not just port/startup retriesThe per-project
last_errortracking is a good addition, but currently it’s only updated in a few paths:
- When
_ensure_port_availableraisesMCPComposerPortError, you storeself._last_errors[project_id] = e.message.- When all retries in
_do_start_project_composerfail, you storeself._last_errors[project_id] = last_error.message.- On success you call
self.clear_last_error(project_id).However, several early failure paths in
_do_start_project_composerraiseMCPComposerConfigError(no auth settings, invalid/missing port, missing host, or_validate_oauth_settingsfailures) before any of those assignments, soget_last_errorwill remain unset or stale for those cases. That undermines the “persist MCP Composer service errors per project for UI display” goal.To make error reporting consistent, consider centralizing this in
start_project_composer:
- Wrap the
await self._do_start_project_composer(...)call in atry/except MCPComposerErrorblock.- In the
except, callself.set_last_error(project_id, e.message)and re-raise.- Inside
_do_start_project_composer, useset_last_errorrather than assigningself._last_errors[...]directly for the port/retry paths, and keepclear_last_erroron success.This way every
MCPComposerError, including configuration issues, reliably updateslast_errorfor theget_project_composer_urlendpoint to surface.Also applies to: 984-1015, 1050-1072, 1142-1157

44-82: Fix options override so internal cache updates always run inusePatchFlowsMCPThe per-project mutation key and targeted invalidations look good, but the options wiring here is fragile:
const mutation = mutate(["usePatchFlowsMCP", params.project_id], patchFlowMCP, { onSuccess: (data, variables, context) => { /* internal updates */ }, onSettled: () => { /* invalidate per-project flows */ }, ...options, });Because
...optionscomes last, any caller that passesoptions.onSuccessoroptions.onSettledwill completely replace the internal handlers, so:
auth_settingswon't be updated in theuseGetFlowsMCPcache.project-composer-urland the per-projectuseGetFlowsMCPqueries won't be invalidated.
usePatchInstallMCPuses the safer pattern (...optionsfirst, then anonSuccessthat also callsoptions?.onSuccess), which is what we want here too.A minimal fix:
- const mutation: UseMutationResult< - PatchFlowMCPResponse, - any, - PatchFlowMCPRequest - > = mutate(["usePatchFlowsMCP", params.project_id], patchFlowMCP, { - onSuccess: (data, variables, context) => { + const mutation: UseMutationResult< + PatchFlowMCPResponse, + any, + PatchFlowMCPRequest + > = mutate(["usePatchFlowsMCP", params.project_id], patchFlowMCP, { + ...options, + onSuccess: (data, variables, context) => { const authSettings = (variables as PatchFlowMCPRequest).auth_settings; const currentMCPData = queryClient.getQueryData([ "useGetFlowsMCP", params.project_id, ]); if (currentMCPData && authSettings !== undefined) { queryClient.setQueryData(["useGetFlowsMCP", params.project_id], { ...currentMCPData, auth_settings: authSettings, }); } queryClient.invalidateQueries({ queryKey: ["project-composer-url", params.project_id], }); - if (options?.onSuccess) { - options.onSuccess(data, variables, context); - } + options?.onSuccess?.(data, variables, context); }, - onSettled: () => { - queryClient.invalidateQueries({ - queryKey: ["useGetFlowsMCP", params.project_id], - }); - }, - ...options, + onSettled: (data, error, variables, context) => { + queryClient.invalidateQueries({ + queryKey: ["useGetFlowsMCP", params.project_id], + }); + options?.onSettled?.(data, error, variables, context); + }, });This ensures the internal cache updates/invalidation always run while still honoring any callbacks provided via
options.
🧹 Nitpick comments (10)
src/lfx/tests/unit/custom/custom_component/test_component.py (2)
117-117: Consider moving the import to module level.While functionally correct, importing
AsyncMockinside the function is unconventional. Consider moving it to the top of the file alongside the otherunittest.mockimports for better code organization.Apply this diff to move the import:
from typing import Any -from unittest.mock import MagicMock +from unittest.mock import AsyncMock, MagicMock import pytestAnd remove the import from inside the function:
async def test_send_message_without_database(): - from unittest.mock import AsyncMock - component = Component()
132-140: Consider adding assertions to verify the mock behavior.The test could be strengthened by:
- Asserting that
result.idis set to verify the mock worked correctly- Using
assert_called_once_with(message)instead of justassert_called_once()to verify the correct argument was passedApply this diff to add the assertions:
result = await component.send_message(message) assert isinstance(result, Message) assert result.text == "Hello" assert result.sender == "User" assert result.sender_name == "Test" + assert result.id == "test-message-id" # Verify the message was stored (mock was called) - component._store_message.assert_called_once() + component._store_message.assert_called_once_with(message) # The focus is on testing the message handling logic, not the database persistence layer assert event_manager.on_message.calledsrc/frontend/src/modals/authModal/index.tsx (1)
81-101: OAuth auto-sync logic looks correct; consider clearing URLs when port is emptiedThe
handleAuthFieldChangeauto-sync foroauthHost/oauthPortcorrectly derivesoauthServerUrlandoauthCallbackPathand aligns with the new tests and desired re-sync behavior when host/port change.One minor UX edge case: when the user clears the Port field (empty string), the existing
oauthServerUrl/oauthCallbackPathare left pointing at the old port. Consider clearing or updating those fields whenportbecomes empty so the form doesn’t display a now-invalid URL.src/backend/base/langflow/api/v1/mcp_projects.py (2)
411-424: Auth rollback + composer orchestration mostly solid; consider clarifying behavior and rollback intentThe new flow around
original_auth_settings,should_handle_mcp_composer, and the commit-at-end pattern makes sense and aligns with the PR goals:
- Expected
MCPComposerErrorcases persist auth settings and surface an error payload while not rolling back, which lets the UI show composer failures without losing OAuth config.- Unexpected exceptions roll back via
project.auth_settings = original_auth_settingsand a raisedHTTPException, so the session context should abort without committing changes.A couple of tweaks worth considering:
Clarify commit semantics vs. comment
The comment
# Only commit if composer started successfully (or wasn't needed)is slightly misleading: in theMCPComposerErrorbranch you intentionally do commit auth changes even when composer fails, to satisfy “persist settings, show error” behavior.Consider updating the comment to reflect the actual intent, e.g.:
# Commit project/auth changes unless an unexpected error occurred # (composer startup failures are persisted so the UI can show errors)Make rollback intent explicit
You currently snapshot
original_auth_settings = project.auth_settingsand then on unexpected errors do:project.auth_settings = original_auth_settings raise HTTPException(...)Given the surrounding
session_scope, the transaction will be rolled back anyway, but this assignment may give a false sense of “guaranteed rollback” ifhandle_auth_settings_updatemutates the dict in place.If you genuinely need an in-process rollback before the session context rolls back, consider copying the structure:
import copy original_auth_settings = copy.deepcopy(project.auth_settings) if project.auth_settings else NoneOtherwise, you could drop the manual assignment and rely purely on the transaction rollback for clarity.
Also applies to: 447-524
777-790: Per-project composerlast_errorexposure works; confirm whether errors should be one-shot or persistentThe new behavior in
get_project_composer_urlto:
- Return a stored
last_errorwhenshould_use_mcp_composer(project)isFalse, and- Clear
last_erroronly after a successful composer URL retrievalis coherent with the idea of “remember the last OAuth failure even if composer is currently not usable”.
Two points to double-check:
Lifetime of
last_errorwhen composer is permanently disabledIf MCP Composer is turned off globally after a failure,
should_use_mcp_composerwill remainFalseandlast_errorwill never be cleared by this endpoint. That’s probably fine, but consider whether the UI expects this to behave like a one-shot error (cleared after displaying once) versus a persistent banner until the next successful OAuth/composer run.Symmetry with other paths that clear
last_errorYou clear
last_errorexplicitly on:
- successful start in the PATCH handler, and
- explicit OAuth disable (stop-composer branch).
Confirm that these three places (PATCH success, OAuth disable, composer-url success) cover all the scenarios you care about, and that you don’t need to clear
last_errorwhen auth type changes away from OAuth through other flows.If the current behavior is intentional, this is good; if not, adding an explicit clear (or documenting persistence) would avoid surprises later.
Also applies to: 804-808

1-2: Confirm thatuseQueryClientshares the same QueryClient used insideUseRequestProcessorYou now call
useQueryClient()directly and use it toremoveQueriesfor["project-composer-url", projectId], whileusePatchFlowsMCPinternally gets its ownqueryClientfromUseRequestProcessor.If
UseRequestProcessoris also usinguseQueryClientunder the hood, this is fine. If it creates its own QueryClient instance, you’d end up clearing queries on a different client than the one the mutation is invalidating, which would be confusing and could leave stale data around.Please double-check that:
UseRequestProcessorand this hook are wired to the same React Query client (i.e., they both operate within the sameQueryClientProviderand use the same underlying instance).- The query key you remove (
["project-composer-url", projectId]) exactly matches the one used inuseGetProjectComposerUrl.If they are aligned, this pattern is good; if not, consider exposing
queryClientfromUseRequestProcessorand reusing that instead of callinguseQueryClienthere.Also applies to: 48-48, 209-221
src/lfx/tests/unit/services/settings/test_mcp_composer.py (2)
21-38: Port-availability tests may be slightly flaky due to hard-coded portsUsing fixed high ports (59999, 59998) is usually fine but can still collide with other processes on CI, causing intermittent failures.
Consider making the “free port” test more robust by letting the OS allocate a port and then testing it after closing the socket, e.g.:
with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s: s.bind(("localhost", 0)) free_port = s.getsockname()[1] assert mcp_service._is_port_available(free_port) is TrueThis reduces the chance of port collisions across environments.
127-176: Auth-config change detection tests align with_has_auth_config_changedbehaviorThese tests cover the main branches of
_has_auth_config_changed(port changes, identical configs, auth_type change, both/oneNone) and match the documented implementation that compares OAuth-prefixed keys and relevant fields.You might later add a case for subtle normalization differences (e.g., whitespace or int vs. str for ports) to exercise
_normalize_config_value, but the current set already exercises the core logic well.src/lfx/tests/unit/services/settings/test_mcp_composer_windows.py (2)
182-374: Windows temp-file and non-Windows pipe handling tests are thorough and aligned with the service designThe temp-file tests cover:
- Windows path:
NamedTemporaryFileusage and ensuringsubprocess.Popenreceives real file handles instead ofPIPE.- Async reading and cleanup via
_read_process_output_and_extract_error, verifying both contents and that temp files are removed.- Successful-start path cleaning up temp files after
_start_project_composer_processreturns.- Non-Windows path: asserting that stdout/stderr use
subprocess.PIPEwhenplatform.system()is not"Windows".These tests exercise both success and failure/cleanup paths and match the Windows-specific design in the service snippets. The use of real temp files for the read/cleanup tests is appropriate and keeps behavior close to production.
473-523: Retry robustness test nicely covers zombie-cleanup failures
test_zombie_cleanup_failure_is_non_fatal_during_retrysets up:
- A first
_start_project_composer_processattempt that raisesMCPComposerStartupError._kill_zombie_mcp_processesraising an exception.- A second attempt that succeeds.
Asserting that
call_count == 2and thatproject_idis present inproject_composersconfirms that:
- Zombie cleanup errors do not abort retries.
- Success on a later attempt still leads to proper tracking.
The async side-effect function for
_start_project_composer_processis a good pattern here.

1-275: Comprehensive and aligned test coverage for OAuth auto-syncThe test suite thoroughly covers the new OAuth auto-sync behavior (host/port, callback, manual overrides, save payload, existing settings, and non-OAuth types) and matches the component’s logic. This should give good confidence in the new flow.
src/lfx/src/lfx/services/mcp_composer/service.py (1)
99-239: Port/process ownership and startup monitoring look robust and conservativeThe new helpers for port/process handling and startup monitoring (
_is_port_available,_kill_process_on_port,_kill_zombie_mcp_processes,_is_port_used_by_another_project,_ensure_port_available,_read_process_output_and_extract_error,_read_stream_non_blocking,_start_project_composer_process) form a coherent lifecycle:
- Only kill processes when they’re explicitly associated with the current project (
_port_to_project/_pid_to_project) or, on Windows, clearly identified as MCP Composer zombies.- Avoid killing unknown external processes on occupied ports, instead surfacing clear
MCPComposerPortErrormessages.- Use temp files for stdout/stderr on Windows to avoid pipe deadlocks and clean them up in all success/error paths.
- Monitor startup with repeated port checks and non-blocking log reads, producing structured error logs with obfuscated secrets.
This is well-structured for cross-platform safety and observability; no changes needed here.

376-439: Startup timeout and retry-parameter tests correctly pin the intended behavior
test_startup_timeout_is_80_secondsasserts the defaults onstart_project_composer(max_startup_checks=40,startup_delay=2.0), matching the intended 80s timeout.test_retry_with_increased_timeoutpatches_start_project_composer_processto always fail and then checks that each retry passes through the expectedmax_startup_checksandstartup_delayvalues, accounting for both positional and keyword argument calls.The combination gives good protection against accidental changes to startup timing semantics.
441-471: Stream-reading avoidance tests look accurate for Windows vs Unix behaviorThe tests for
_read_stream_non_blockingcorrectly reflect the implementation:
- On Windows, it should immediately return
""and never touch the stream (peek()/readline()), which is whattest_read_stream_non_blocking_returns_empty_on_windowsasserts.- On Unix-like systems, patching
select.selectand verifying thatreadline()is used and the decoded content is returned matches the documented non-blocking behavior.This gives good coverage of a subtle, platform-specific code path.

I don't believe this is the correct behavior (though, it is cool).

I'm starting to think we should have a fourth auth settings state: Failed, which ensures no mcp server is started for this project, and can store the last error state.

hey @jordanrfrazier ,
We've already implemented something similar with the instant error detection improvements in this PR.
Now we can see error feedback almost in runtime.

The kill_process method is worrisome to me - I can imagine a situation where the composer started on a port then user manually stopped MCP Composer. Then, user started up another application (could be anything) on the same port.
Then, Langflow gets here and kills user's process.
Very serious issue, imo, so we should brainstorm if we have any other options here. (We also may have a similar situation with _do_stop_project_composer?)

Good catch, but this scenario is already protected against. The code only kills processes that Langflow itself started and is actively tracking via self._port_to_project.
For the scenario you described:
- User manually stops MCP Composer
- User starts another application on the same port
- Langflow tries to restart MCP Composer
What actually happens:
- At line 728-732 in _ensure_port_available(), we detect that the port is in use by an unknown process (not in our tracking)
- We explicitly refuse to kill it for security reasons
- We raise MCPComposerPortError asking the user to choose a different port
else:
# Port is in use by unknown process - don't kill it (security concern)
await logger.aerror(
f"Port {port} is in use by an unknown process (not owned by Langflow). "
f"Will not kill external application for security reasons."
)
raise MCPComposerPortError(...)
We only kill processes when:
- The port is owned by the same project trying to restart (line 710) - safe because it's our own stuck process
- The port is in existing_port (line 1083) - which comes from our internal tracking, meaning we started it
The tracking ensures we never kill external applications. If a process isn't in self._port_to_project or self.project_composers, we treat it as external and refuse to touch it.

Updated relevant input classes to ensure telemetry tracking is disabled for these sensitive fields, enhancing data privacy and security. * feat: Enhance telemetry payloads with additional fields and serialization support Added new fields to the ComponentPayload and ComponentInputsPayload classes, including component_id and component_run_id, to improve telemetry data tracking. Introduced a serialize_input_values function to handle JSON serialization of component input values, ensuring robust handling of input data for telemetry purposes. * feat: Implement telemetry input tracking and caching Added functionality to track and cache telemetry input values within the Component class. Introduced a method to determine if inputs should be tracked based on sensitivity and an accessor for retrieving cached telemetry data, enhancing the robustness of telemetry handling. * feat: Add logging for component input telemetry Introduced a new method, log_package_component_inputs, to the TelemetryService for logging telemetry data related to component inputs. This enhancement improves the tracking capabilities of the telemetry system, allowing for more detailed insights into component interactions. * feat: Enhance telemetry logging for component execution Added functionality to log component input telemetry both during successful execution and error cases. Introduced a unique component_run_id for each execution to improve tracking. This update ensures comprehensive telemetry data collection, enhancing the robustness of the telemetry system. * feat: Extend telemetry payload tests and enhance serialization Added tests for the new component_id and component_run_id fields in ComponentPayload and ComponentInputsPayload classes. Introduced a new test suite for ComponentInputTelemetry, covering serialization of various data types and handling of edge cases. This update improves the robustness and coverage of telemetry data handling in the system. * fix: Update default telemetry tracking behavior in BaseInputMixin Changed the default value of track_in_telemetry from True to False in the BaseInputMixin class. Updated documentation to clarify that telemetry tracking is now opt-in and can be explicitly enabled for individual input types, enhancing data privacy and control. * fix: Update telemetry tracking defaults for input types Modified the default value of `track_in_telemetry` for various input classes to enhance data privacy. Regular inputs now default to False, while safe inputs like `IntInput` and `BoolInput` default to True, ensuring explicit opt-in for telemetry tracking. Updated related tests to reflect these changes. * feat: add chunk_index and total_chunks fields to ComponentInputsPayload This commit adds two new optional fields to ComponentInputsPayload: - chunk_index: Index of this chunk in a split payload sequence - total_chunks: Total number of chunks in the split sequence Both fields default to None and use camelCase aliases for serialization. This is Task 1 of the telemetry query parameter splitting implementation. Tests included: - Verify fields exist and can be set - Verify camelCase serialization aliases work correctly - Verify fields default to None when not provided Generated with Claude Code (https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> * refactor: update ComponentInputsPayload to support automatic splitting of oversized inputs This commit enhances the ComponentInputsPayload class by implementing functionality to automatically split input values into multiple chunks if they exceed the maximum URL size limit. Key changes include: - Added methods for calculating URL size, truncating oversized values, and splitting payloads. - Updated component_inputs field to accept a dictionary instead of a string for better handling of input values. - Improved documentation for the ComponentInputsPayload class to reflect the new splitting behavior and usage examples. These changes aim to improve telemetry data handling and ensure compliance with URL length restrictions. * refactor: enhance log_package_component_inputs to handle oversized payloads This commit updates the log_package_component_inputs method in the TelemetryService class to split component input payloads into multiple requests if they exceed the maximum URL size limit. Key changes include: - Added logic to split the payload using the new split_if_needed method. - Each chunk is queued separately for telemetry logging. These improvements ensure better handling of telemetry data while adhering to URL length restrictions. * refactor: centralize maximum telemetry URL size constant This commit introduces a centralized constant, MAX_TELEMETRY_URL_SIZE, to define the maximum URL length for telemetry GET requests. Key changes include: - Added MAX_TELEMETRY_URL_SIZE constant to schema.py for better maintainability. - Updated split_if_needed method in ComponentInputsPayload to use the new constant instead of a hardcoded value. - Adjusted the TelemetryService to reference the centralized constant for URL size limits. These changes enhance code clarity and ensure consistent handling of URL size limits across the telemetry service. * refactor: update ComponentInputsPayload tests to use dictionary inputs This commit modifies the tests for ComponentInputsPayload to utilize a dictionary for component inputs instead of a serialized JSON string. Key changes include: - Renamed the test method to reflect the new input type. - Removed unnecessary serialization steps and assertions related to JSON strings. - Added assertions to verify the correct handling of dictionary inputs. These changes streamline the testing process and improve clarity in how component inputs are represented. * test: add integration tests for telemetry service payload splitting This commit introduces integration tests for the TelemetryService to verify its handling of large and small payloads. Key changes include: - Added tests to ensure large payloads are split into multiple chunks and queued correctly. - Implemented a test to confirm that small payloads are not split and result in a single queued event. - Created a mock settings service for testing purposes. These tests enhance the reliability of the telemetry service by ensuring proper payload management. * test: enhance ComponentInputsPayload tests with additional scenarios This commit expands the test suite for ComponentInputsPayload by adding various scenarios to ensure robust handling of input payloads. Key changes include: - Introduced tests for calculating URL size, ensuring it returns a positive integer and accounts for encoding. - Added tests to verify the splitting logic for large payloads, including checks for chunk metadata and preservation of fixed fields. - Implemented property-based tests using Hypothesis to validate that all chunks respect the maximum URL size and preserve original data. These enhancements improve the reliability and coverage of the ComponentInputsPayload tests, ensuring proper functionality under various conditions. * [autofix.ci] apply automated fixes * optimize query param encoding Co-authored-by: codeflash-ai[bot] <148906541+codeflash-ai[bot]@users.noreply.github.com> * refactor: extract telemetry logging logic into a separate function This commit introduces a new function, _log_component_input_telemetry, to centralize the logic for logging component input telemetry. The function is called in two places within the generate_flow_events function, improving code readability and maintainability by reducing duplication. This change enhances the clarity of telemetry handling in the flow generation process. * refactor: optimize truncation logic in ComponentInputsPayload This commit refines the truncation logic for input values in the ComponentInputsPayload class. The previous binary search method for string values has been simplified, allowing for direct truncation of both string and non-string values. This change enhances code clarity and maintains functionality while ensuring optimal handling of oversized inputs. * refactor: update telemetry tracking logic to respect opt-in flag This commit modifies the telemetry tracking logic in the Component class to change the default behavior of the `track_in_telemetry` attribute from True to False. This adjustment enhances user privacy by requiring explicit consent for tracking input objects in telemetry. The change ensures that sensitive field types are still auto-excluded from tracking, maintaining the integrity of the telemetry data. * refactor: update tests to use dictionary format for component inputs This commit modifies the integration tests for telemetry payload validation and component input telemetry to utilize dictionaries for component inputs instead of serialized JSON strings. Key changes include: - Updated assertions to compare dictionary inputs directly. - Enhanced clarity and maintainability of the test cases by removing unnecessary serialization steps. These changes improve the representation of component inputs in tests, aligning with recent refactoring efforts. * [autofix.ci] apply automated fixes * refactor: specify type for current_chunk_inputs in ComponentInputsPayload This commit updates the type annotation for the current_chunk_inputs variable in the ComponentInputsPayload class to explicitly define it as a dictionary. This change enhances code clarity and maintainability by providing better type information for developers working with the code. * test: add component_id to ComponentPayload tests This commit enhances the test cases for the ComponentPayload class by adding a component_id parameter to various initialization tests. The updates ensure that the component_id is properly tested across different scenarios, including valid parameters, error messages, and edge cases. This change improves the robustness of the tests and aligns with recent updates to the ComponentPayload structure. * [autofix.ci] apply automated fixes * feat: add component_id to ComponentPayload in build_vertex function * fix: update MAX_TELEMETRY_URL_SIZE to 2048 and adjust related tests This commit increases the maximum URL size for telemetry GET requests from 2000 to 2048 bytes to align with Scarf's specifications.

Adds a README, demo script, and comprehensive unit tests for template search functionality. * Add Langflow Agentic MCP server with FastMCP tools Introduces a new MCP (Model Context Protocol) server for Langflow agentic tools using FastMCP. Adds server, CLI, example usage, tests, and comprehensive documentation. Exposes four MCP tools: search_templates, get_template, list_all_tags, and count_templates, enabling AI assistants to query and filter Langflow templates programmatically. * Handle unparameterized list types in schema inputs Adds support for unparameterized list annotations by treating them as lists of strings when converting schemas to Langflow inputs. This ensures nullable array schemas without explicit item types are handled gracefully. * Refactor search_templates to simplify parameters Removed the 'tags' parameter from the search_templates function and set a default value for 'fields'. Updated the call to list_templates to match the new signature, streamlining template search functionality. * Add output item processing for tool results Introduced process_output_item to handle tool output items, attempting to parse text-type items as JSON. This improves downstream handling of tool outputs by converting JSON strings to dictionaries when possible. * Refactor knowledge base path initialization Replaces direct settings access with a lazy-loading function for the knowledge bases root path in Knowledge Ingestion and Knowledge Retrieval starter projects. This improves reliability and consistency when accessing the knowledge base directory, and updates all usages to the new helper function. * Update component_index.json * Add IBM watsonx.ai support to starter projects Introduces IBM watsonx.ai as a selectable model provider in multiple starter project JSONs. Adds new input fields for 'base_url', 'project_id', and 'max_output_tokens' to support IBM watsonx.ai integration. Updates agent component code to handle new provider and its required parameters. * Add Ollama to supported LLM providers in starter projects Ollama has been added as a supported provider alongside Anthropic, Google Generative AI, OpenAI, and IBM watsonx.ai in all starter project JSON files. This expands the available options for LLM integration in initial setup templates. * Update Ollama model input constants and logic Refactored model_input_constants.py to update the OLLAMA_MODEL_INPUTS and OLLAMA_MODEL_INPUTS_MAP. Modified ollama.py to use the new input mapping and improved input handling for Ollama components. * Add flow creation from template MCP tool Introduces a new MCP tool for creating flows from starter templates in Langflow Agentic. Adds the utility function `create_flow_from_template_and_get_link` and exposes it via the FastMCP server, allowing users to create flows by template id and receive a UI link. Updates imports and documentation accordingly. * Add component search utilities and MCP tools to server Introduces new component search and retrieval tools to the MCP server, including endpoints for searching, listing, and counting components. Adds support functions in support.py for data normalization and a new component_search.py utility module. Updates the Nvidia Remix starter project to use the latest MCPToolsComponent code. * Add flow graph visualization utilities Introduces async utility functions for generating ASCII and text representations of flow graphs, as well as metadata summaries. These utilities support fetching flows by ID or name, error handling, and integration with Langflow's graph and logging modules. * Add flow component operations utilities and MCP tools Introduces flow component management utilities in `flow_component.py` for retrieving, updating, and listing component field values. Exposes new MCP tools in `server.py` for accessing component details, field values, updating fields, and listing all fields within a flow component. * Add SystemMessageGen flow and update MCPTools Introduces SystemMessageGen.json flow for agentic system message generation and updates MCPTools component logic in flow_component.py to support new flow structure and tool handling. * feat: init aiButton create an aiButton that opens the prompt modal for demoing add multiinput mixin * Update component_index.json * Refactor SystemMessageGen flow and remove unused init files Updated SystemMessageGen.json to support custom instructions, OpenAI model configuration, and improved agent settings. Removed unused __init__.py files from agentic, core, tools, and utils directories to clean up the codebase. * update to the mcp component * Add verify_ssl option to MCPToolsComponent Introduces a 'verify_ssl' boolean input to MCPToolsComponent for controlling SSL certificate verification in HTTPS connections. The option is added to the server config if not present, allowing users to disable verification for development or testing with self-signed certificates. * Optimize tool dropdown handling and output processing Improves logic for updating tool dropdown options by checking if the server has changed and whether tool mode is active, reducing unnecessary updates. Adds a process_output_item method to parse tool output as JSON when appropriate, enhancing output handling. * [autofix.ci] apply automated fixes * [autofix.ci] apply automated fixes (attempt 2/3) * [autofix.ci] apply automated fixes (attempt 3/3) * feat: init onclick assistant prompt generation first pass at on button click generate input and auto fill a field * Replace MCPTools with Prompt Template in SystemMessageGen flow Updated the SystemMessageGen.json flow to use the Prompt Template and Parser components instead of MCPTools. Adjusted edges, nodes, and component configurations to reflect the new prompt-based workflow, removing tool selection and execution logic in favor of prompt generation and parsing. * Update SystemMessageGen flow and frontend dependencies Refactored edge connections and metadata in SystemMessageGen.json to improve flow logic and updated endpoint name. Added new optional and peer dependencies to package-lock.json, including @mapbox/node-pre-gyp and related packages, to support canvas and other modules. * Update user authentication in simplified_run_flow endpoint Replaces the dependency on api_key_security with CurrentActiveUser for the api_key_user parameter in the simplified_run_flow endpoint. This change is part of a TODO to create a new endpoint and may affect how user authentication is handled. * feat: hook everything up and have onclick prompt hook up commit * Add auto-configuration for Agentic MCP server Introduces utilities and startup logic to automatically configure the Langflow Agentic MCP server for all users when the agentic experience is enabled. Adds a new settings flag `agentic_experience` to control this feature, and updates the main server startup to trigger configuration. This enables agentic tools for flow/component operations, template search, and graph visualization in MCP clients. * Enable agentic MCP server and improve initialization Set agentic_experience to True by default in settings. Refactor agentic MCP server initialization in main.py to run in the background with a delay and retry logic, improving startup reliability. Update function calls to use 'current_user' instead of 'user' in agentic_mcp.py for consistency. * Update user authentication in simplified_run_flow Modified the api_key_user parameter to accept either CurrentActiveUser or UserRead from api_key_security, supporting both Bearer and session authentication methods. * revert the apikeu_user changes * test new api endpoint * Refactor agent flow and update component inputs Updated SystemMessageGen.json to refactor edge connections and node IDs for agentic flow. Added 'base_url' as a required input, enabled 'ai_enabled' for agent description, and replaced static memory input handling with dynamic retrieval via get_base_inputs(). Also improved tool callback setup and updated code hash and last_updated metadata. * Improve agentic flow creation and updating logic Enhances the agentic flow setup to extract flow_id and endpoint_name from JSON, update existing flows by ID or endpoint_name, and create new flows if they don't exist. Adds detailed logging and ensures flows are up-to-date in the user's Langflow Assistant folder. * chore: aibutton clean up * chore: add assistant store * Update SystemMessageGen.json * Update agentic_mcp.py * Update component_index.json * Fix agent input extraction from Message objects Agents now correctly extract and use the text content from Message objects, rather than passing the entire object or its string representation. This resolves issues where agents received verbose message representations instead of just the intended string input, and includes improved handling for multimodal content. Corresponding unit and integration tests have been added to verify this behavior for both OpenAI and Anthropic agents. * Add TemplateAssistant Langflow flow definition Introduces TemplateAssistant.json, a comprehensive Langflow flow configuration for agentic workflows. This flow integrates AstraDB, MCP Tools, and user input/output nodes, enabling document ingestion, search, and tool orchestration within the Langflow backend. * Improve MCPToolsComponent server/tool config refresh Refactored MCPToolsComponent to better handle tool and server config refreshes, especially when the MCP server changes. Added logic to avoid unnecessary clearing of tool inputs and options, and improved caching and UI update behavior for tool selection. Also updated related flow and starter project JSON files to reflect these changes. * auto add Global Variables for Agentic Experience * chore: clean up and get button working again * cleanup .md * fix:ruff, Refactor agentic utils and improve error handling Introduces shared default field lists for template/component search, refactors exception handling to use logger and add finally/else blocks, and improves type hinting with TYPE_CHECKING. Updates file opening to use Path objects, enhances error logging in template search, and removes the unused test_template_search.py file. * fix:ruff Expand exception handling in agentic MCP utilities Broadened exception handling in agentic MCP server and variable management functions to catch specific errors such as HTTPException, SQLAlchemyError, and common system exceptions. This improves robustness and error logging during server configuration, removal, and variable initialization. * aka-clean-up-1 * Remove duplicate process_output_item method Deleted two redundant definitions of the process_output_item method from MCPToolsComponent to clean up the code and prevent confusion. * [autofix.ci] apply automated fixes * [autofix.ci] apply automated fixes (attempt 2/3) * [autofix.ci] apply automated fixes (attempt 3/3) * [autofix.ci] apply automated fixes * [autofix.ci] apply automated fixes (attempt 2/3) * [autofix.ci] apply automated fixes * Refactor service usage and improve project deletion logging Refactored login API to reuse a single settings service instance.

Updated documentation to clarify that telemetry tracking is now opt-in and can be explicitly enabled for individual input types, enhancing data privacy and control. * fix: Update telemetry tracking defaults for input types Modified the default value of `track_in_telemetry` for various input classes to enhance data privacy. Regular inputs now default to False, while safe inputs like `IntInput` and `BoolInput` default to True, ensuring explicit opt-in for telemetry tracking. Updated related tests to reflect these changes. * feat: add chunk_index and total_chunks fields to ComponentInputsPayload This commit adds two new optional fields to ComponentInputsPayload: - chunk_index: Index of this chunk in a split payload sequence - total_chunks: Total number of chunks in the split sequence Both fields default to None and use camelCase aliases for serialization. This is Task 1 of the telemetry query parameter splitting implementation. Tests included: - Verify fields exist and can be set - Verify camelCase serialization aliases work correctly - Verify fields default to None when not provided Generated with Claude Code (https://claude.com/claude-code) * refactor: update ComponentInputsPayload to support automatic splitting of oversized inputs This commit enhances the ComponentInputsPayload class by implementing functionality to automatically split input values into multiple chunks if they exceed the maximum URL size limit. Key changes include: - Added methods for calculating URL size, truncating oversized values, and splitting payloads. - Updated component_inputs field to accept a dictionary instead of a string for better handling of input values. - Improved documentation for the ComponentInputsPayload class to reflect the new splitting behavior and usage examples. These changes aim to improve telemetry data handling and ensure compliance with URL length restrictions. * refactor: enhance log_package_component_inputs to handle oversized payloads This commit updates the log_package_component_inputs method in the TelemetryService class to split component input payloads into multiple requests if they exceed the maximum URL size limit. Key changes include: - Added logic to split the payload using the new split_if_needed method. - Each chunk is queued separately for telemetry logging. These improvements ensure better handling of telemetry data while adhering to URL length restrictions. * refactor: centralize maximum telemetry URL size constant This commit introduces a centralized constant, MAX_TELEMETRY_URL_SIZE, to define the maximum URL length for telemetry GET requests. Key changes include: - Added MAX_TELEMETRY_URL_SIZE constant to schema.py for better maintainability. - Updated split_if_needed method in ComponentInputsPayload to use the new constant instead of a hardcoded value. - Adjusted the TelemetryService to reference the centralized constant for URL size limits. These changes enhance code clarity and ensure consistent handling of URL size limits across the telemetry service. * refactor: update ComponentInputsPayload tests to use dictionary inputs This commit modifies the tests for ComponentInputsPayload to utilize a dictionary for component inputs instead of a serialized JSON string. Key changes include: - Renamed the test method to reflect the new input type. - Removed unnecessary serialization steps and assertions related to JSON strings. - Added assertions to verify the correct handling of dictionary inputs. These changes streamline the testing process and improve clarity in how component inputs are represented. * test: add integration tests for telemetry service payload splitting This commit introduces integration tests for the TelemetryService to verify its handling of large and small payloads. Key changes include: - Added tests to ensure large payloads are split into multiple chunks and queued correctly. - Implemented a test to confirm that small payloads are not split and result in a single queued event. - Created a mock settings service for testing purposes. These tests enhance the reliability of the telemetry service by ensuring proper payload management. * test: enhance ComponentInputsPayload tests with additional scenarios This commit expands the test suite for ComponentInputsPayload by adding various scenarios to ensure robust handling of input payloads. Key changes include: - Introduced tests for calculating URL size, ensuring it returns a positive integer and accounts for encoding. - Added tests to verify the splitting logic for large payloads, including checks for chunk metadata and preservation of fixed fields. - Implemented property-based tests using Hypothesis to validate that all chunks respect the maximum URL size and preserve original data. These enhancements improve the reliability and coverage of the ComponentInputsPayload tests, ensuring proper functionality under various conditions. * [autofix.ci] apply automated fixes * optimize query param encoding * refactor: extract telemetry logging logic into a separate function This commit introduces a new function, _log_component_input_telemetry, to centralize the logic for logging component input telemetry. The function is called in two places within the generate_flow_events function, improving code readability and maintainability by reducing duplication. This change enhances the clarity of telemetry handling in the flow generation process. * refactor: optimize truncation logic in ComponentInputsPayload This commit refines the truncation logic for input values in the ComponentInputsPayload class. The previous binary search method for string values has been simplified, allowing for direct truncation of both string and non-string values. This change enhances code clarity and maintains functionality while ensuring optimal handling of oversized inputs. * refactor: update telemetry tracking logic to respect opt-in flag This commit modifies the telemetry tracking logic in the Component class to change the default behavior of the `track_in_telemetry` attribute from True to False. This adjustment enhances user privacy by requiring explicit consent for tracking input objects in telemetry. The change ensures that sensitive field types are still auto-excluded from tracking, maintaining the integrity of the telemetry data. * refactor: update tests to use dictionary format for component inputs This commit modifies the integration tests for telemetry payload validation and component input telemetry to utilize dictionaries for component inputs instead of serialized JSON strings. Key changes include: - Updated assertions to compare dictionary inputs directly. - Enhanced clarity and maintainability of the test cases by removing unnecessary serialization steps. These changes improve the representation of component inputs in tests, aligning with recent refactoring efforts. * [autofix.ci] apply automated fixes * refactor: specify type for current_chunk_inputs in ComponentInputsPayload This commit updates the type annotation for the current_chunk_inputs variable in the ComponentInputsPayload class to explicitly define it as a dictionary. This change enhances code clarity and maintainability by providing better type information for developers working with the code. * test: add component_id to ComponentPayload tests This commit enhances the test cases for the ComponentPayload class by adding a component_id parameter to various initialization tests. The updates ensure that the component_id is properly tested across different scenarios, including valid parameters, error messages, and edge cases. This change improves the robustness of the tests and aligns with recent updates to the ComponentPayload structure. * [autofix.ci] apply automated fixes * feat: add component_id to ComponentPayload in build_vertex function * fix: update MAX_TELEMETRY_URL_SIZE to 2048 and adjust related tests This commit increases the maximum URL size for telemetry GET requests from 2000 to 2048 bytes to align with Scarf's specifications.

Adds a README, demo script, and comprehensive unit tests for template search functionality. * Add Langflow Agentic MCP server with FastMCP tools Introduces a new MCP (Model Context Protocol) server for Langflow agentic tools using FastMCP. Adds server, CLI, example usage, tests, and comprehensive documentation. Exposes four MCP tools: search_templates, get_template, list_all_tags, and count_templates, enabling AI assistants to query and filter Langflow templates programmatically. * Handle unparameterized list types in schema inputs Adds support for unparameterized list annotations by treating them as lists of strings when converting schemas to Langflow inputs. This ensures nullable array schemas without explicit item types are handled gracefully. * Refactor search_templates to simplify parameters Removed the 'tags' parameter from the search_templates function and set a default value for 'fields'. Updated the call to list_templates to match the new signature, streamlining template search functionality. * Add output item processing for tool results Introduced process_output_item to handle tool output items, attempting to parse text-type items as JSON. This improves downstream handling of tool outputs by converting JSON strings to dictionaries when possible. * Refactor knowledge base path initialization Replaces direct settings access with a lazy-loading function for the knowledge bases root path in Knowledge Ingestion and Knowledge Retrieval starter projects. This improves reliability and consistency when accessing the knowledge base directory, and updates all usages to the new helper function. * Update component_index.json * Add IBM watsonx.ai support to starter projects Introduces IBM watsonx.ai as a selectable model provider in multiple starter project JSONs. Adds new input fields for 'base_url', 'project_id', and 'max_output_tokens' to support IBM watsonx.ai integration. Updates agent component code to handle new provider and its required parameters. * Add Ollama to supported LLM providers in starter projects Ollama has been added as a supported provider alongside Anthropic, Google Generative AI, OpenAI, and IBM watsonx.ai in all starter project JSON files. This expands the available options for LLM integration in initial setup templates. * Update Ollama model input constants and logic Refactored model_input_constants.py to update the OLLAMA_MODEL_INPUTS and OLLAMA_MODEL_INPUTS_MAP. Modified ollama.py to use the new input mapping and improved input handling for Ollama components. * Add flow creation from template MCP tool Introduces a new MCP tool for creating flows from starter templates in Langflow Agentic. Adds the utility function `create_flow_from_template_and_get_link` and exposes it via the FastMCP server, allowing users to create flows by template id and receive a UI link. Updates imports and documentation accordingly. * Add component search utilities and MCP tools to server Introduces new component search and retrieval tools to the MCP server, including endpoints for searching, listing, and counting components. Adds support functions in support.py for data normalization and a new component_search.py utility module. Updates the Nvidia Remix starter project to use the latest MCPToolsComponent code. * Add flow graph visualization utilities Introduces async utility functions for generating ASCII and text representations of flow graphs, as well as metadata summaries. These utilities support fetching flows by ID or name, error handling, and integration with Langflow's graph and logging modules. * Add flow component operations utilities and MCP tools Introduces flow component management utilities in `flow_component.py` for retrieving, updating, and listing component field values. Exposes new MCP tools in `server.py` for accessing component details, field values, updating fields, and listing all fields within a flow component. * Add SystemMessageGen flow and update MCPTools Introduces SystemMessageGen.json flow for agentic system message generation and updates MCPTools component logic in flow_component.py to support new flow structure and tool handling. * feat: init aiButton create an aiButton that opens the prompt modal for demoing add multiinput mixin * Update component_index.json * Refactor SystemMessageGen flow and remove unused init files Updated SystemMessageGen.json to support custom instructions, OpenAI model configuration, and improved agent settings. Removed unused __init__.py files from agentic, core, tools, and utils directories to clean up the codebase. * update to the mcp component * Add verify_ssl option to MCPToolsComponent Introduces a 'verify_ssl' boolean input to MCPToolsComponent for controlling SSL certificate verification in HTTPS connections. The option is added to the server config if not present, allowing users to disable verification for development or testing with self-signed certificates. * Optimize tool dropdown handling and output processing Improves logic for updating tool dropdown options by checking if the server has changed and whether tool mode is active, reducing unnecessary updates. Adds a process_output_item method to parse tool output as JSON when appropriate, enhancing output handling. * [autofix.ci] apply automated fixes * [autofix.ci] apply automated fixes (attempt 2/3) * [autofix.ci] apply automated fixes (attempt 3/3) * feat: init onclick assistant prompt generation first pass at on button click generate input and auto fill a field * Replace MCPTools with Prompt Template in SystemMessageGen flow Updated the SystemMessageGen.json flow to use the Prompt Template and Parser components instead of MCPTools. Adjusted edges, nodes, and component configurations to reflect the new prompt-based workflow, removing tool selection and execution logic in favor of prompt generation and parsing. * Update SystemMessageGen flow and frontend dependencies Refactored edge connections and metadata in SystemMessageGen.json to improve flow logic and updated endpoint name. Added new optional and peer dependencies to package-lock.json, including @mapbox/node-pre-gyp and related packages, to support canvas and other modules. * Update user authentication in simplified_run_flow endpoint Replaces the dependency on api_key_security with CurrentActiveUser for the api_key_user parameter in the simplified_run_flow endpoint. This change is part of a TODO to create a new endpoint and may affect how user authentication is handled. * feat: hook everything up and have onclick prompt hook up commit * Add auto-configuration for Agentic MCP server Introduces utilities and startup logic to automatically configure the Langflow Agentic MCP server for all users when the agentic experience is enabled. Adds a new settings flag `agentic_experience` to control this feature, and updates the main server startup to trigger configuration. This enables agentic tools for flow/component operations, template search, and graph visualization in MCP clients. * Enable agentic MCP server and improve initialization Set agentic_experience to True by default in settings. Refactor agentic MCP server initialization in main.py to run in the background with a delay and retry logic, improving startup reliability. Update function calls to use 'current_user' instead of 'user' in agentic_mcp.py for consistency. * Update user authentication in simplified_run_flow Modified the api_key_user parameter to accept either CurrentActiveUser or UserRead from api_key_security, supporting both Bearer and session authentication methods. * revert the apikeu_user changes * test new api endpoint * Refactor agent flow and update component inputs Updated SystemMessageGen.json to refactor edge connections and node IDs for agentic flow. Added 'base_url' as a required input, enabled 'ai_enabled' for agent description, and replaced static memory input handling with dynamic retrieval via get_base_inputs(). Also improved tool callback setup and updated code hash and last_updated metadata. * Improve agentic flow creation and updating logic Enhances the agentic flow setup to extract flow_id and endpoint_name from JSON, update existing flows by ID or endpoint_name, and create new flows if they don't exist. Adds detailed logging and ensures flows are up-to-date in the user's Langflow Assistant folder. * chore: aibutton clean up * chore: add assistant store * Update SystemMessageGen.json * Update agentic_mcp.py * Update component_index.json * Fix agent input extraction from Message objects Agents now correctly extract and use the text content from Message objects, rather than passing the entire object or its string representation. This resolves issues where agents received verbose message representations instead of just the intended string input, and includes improved handling for multimodal content. Corresponding unit and integration tests have been added to verify this behavior for both OpenAI and Anthropic agents. * Add TemplateAssistant Langflow flow definition Introduces TemplateAssistant.json, a comprehensive Langflow flow configuration for agentic workflows. This flow integrates AstraDB, MCP Tools, and user input/output nodes, enabling document ingestion, search, and tool orchestration within the Langflow backend. * Improve MCPToolsComponent server/tool config refresh Refactored MCPToolsComponent to better handle tool and server config refreshes, especially when the MCP server changes. Added logic to avoid unnecessary clearing of tool inputs and options, and improved caching and UI update behavior for tool selection. Also updated related flow and starter project JSON files to reflect these changes. * auto add Global Variables for Agentic Experience * chore: clean up and get button working again * cleanup .md * fix:ruff, Refactor agentic utils and improve error handling Introduces shared default field lists for template/component search, refactors exception handling to use logger and add finally/else blocks, and improves type hinting with TYPE_CHECKING. Updates file opening to use Path objects, enhances error logging in template search, and removes the unused test_template_search.py file. * fix:ruff Expand exception handling in agentic MCP utilities Broadened exception handling in agentic MCP server and variable management functions to catch specific errors such as HTTPException, SQLAlchemyError, and common system exceptions. This improves robustness and error logging during server configuration, removal, and variable initialization. * aka-clean-up-1 * Remove duplicate process_output_item method Deleted two redundant definitions of the process_output_item method from MCPToolsComponent to clean up the code and prevent confusion. * [autofix.ci] apply automated fixes * [autofix.ci] apply automated fixes (attempt 2/3) * [autofix.ci] apply automated fixes (attempt 3/3) * [autofix.ci] apply automated fixes * [autofix.ci] apply automated fixes (attempt 2/3) * [autofix.ci] apply automated fixes * Refactor service usage and improve project deletion logging Refactored login API to reuse a single settings service instance.

This pull request introduces several improvements and bug fixes to both the backend and frontend of the project, focusing on more robust handling of MCP Composer errors, improved synchronization of OAuth settings in the authentication modal, and better frontend cache management. The changes enhance user feedback during authentication issues, ensure correct UI state synchronization, and improve test coverage for OAuth field auto-sync behavior.
Backend improvements to MCP Composer error handling and commit logic:
get_project_composer_urlendpoint now returns the last error if OAuth setup previously failed, even if OAuth is currently disabled for the project. [1] [2]ResourceWarninglogs from SSE connections in the backend to reduce log clutter.Frontend improvements to OAuth authentication modal and cache management:
AuthModalnow auto-synchronizes the Server URL and Callback Path fields whenever the OAuth Host or Port fields are changed, ensuring consistent and user-friendly configuration. Manual edits are preserved unless fields are changed again.Frontend cache and query management:
useMcpServerhook adds state for tracking slow composer responses and waiting status, laying the groundwork for better user feedback during long-running operations. [1] [2] [3]Summary by CodeRabbit
