charset=UTF-8 Content-Transfer-Encoding: 8bit This commit introduces a complete real-time monitoring ecosystem with three distinct approaches: **New Features:** - Server-Sent Events (SSE) API for HTTP streaming task updates - MCP real-time monitoring tools (watch_task, watch_tasks) for AI assistant integration - Enhanced Web UI with file upload and directory batch processing capabilities - Large file handling strategy with automatic size detection and temporary file processing - Script entry points for easier command invocation (uv run server, uv run mcp_client) **API Enhancements:** - /api/v1/sse/task/{task_id} - Monitor single task progress via SSE - /api/v1/sse/tasks - Monitor all tasks with optional status filtering - /api/v1/sse/stats - Get active SSE connection statistics - Improved task queue with better error handling and progress tracking **Client Examples:** - examples/pure_mcp_client.py - Pure MCP protocol implementation - examples/hybrid_http_sse_client.py - HTTP + SSE hybrid approach **Infrastructure Improvements:** - Fixed logger configuration issues (loguru integration) - Resolved task parameter passing bugs for large document processing - Enhanced monitoring UI with smart refresh instead of full page reloads - Comprehensive bilingual documentation (English/Chinese) - Standardized code comments to English - Updated .gitignore to exclude *.egg-info/ directories **Technical Details:** - Real-time progress updates via WebSocket, SSE, and MCP protocols - 50KB file size limit in UI with guidance for larger files - Automatic temporary file creation for documents ≥10KB in MCP client - Concurrent task monitoring with progress history tracking - Connection management and cleanup for SSE streams --- .gitignore | 4 +- CLAUDE.md | 39 ++- README.md | 68 +++- README_CN.md | 68 +++- api/sse_routes.py | 252 +++++++++++++++ api/task_routes.py | 20 ++ config.py | 4 + config/sky.yml | 104 ++++++ core/logging.py | 6 + core/routes.py | 2 + env.example | 6 +- examples/hybrid_http_sse_client.py | 230 ++++++++++++++ examples/pure_mcp_client.py | 233 ++++++++++++++ mcp_server.py | 266 +++++++++++++++- monitoring/task_monitor.py | 471 +++++++++++++++++++++++++--- pyproject.toml | 9 + services/neo4j_knowledge_service.py | 4 +- services/task_processors.py | 59 ++-- services/task_queue.py | 64 +++- services/task_storage.py | 41 ++- start.py (update service checks) | 0 21 files changed, 1849 insertions(+), 101 deletions(-) create mode 100644 api/sse_routes.py create mode 100644 config/sky.yml create mode 100644 examples/hybrid_http_sse_client.py create mode 100644 examples/pure_mcp_client.py delete mode 100644 start.py (update service checks) diff --git a/.gitignore b/.gitignore index d44dbe1..6f8a414 100644 --- a/.gitignore +++ b/.gitignore @@ -21,6 +21,7 @@ node_modules/ ## Build build/ dist/ +*.egg-info/ ## Logs logs/ @@ -41,4 +42,5 @@ data/ ## .cursor .cursor/ docs/ -tests/ \ No newline at end of file +tests/ +.aider* diff --git a/CLAUDE.md b/CLAUDE.md index ef128ce..3047f32 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -35,6 +35,10 @@ python start.py # Start MCP server (for AI assistant integration) python start_mcp.py +# Using script entry points (after uv sync) +uv run server +uv run mcp_client + # Direct FastAPI startup python main.py ``` @@ -122,8 +126,39 @@ The system uses LlamaIndex's `KnowledgeGraphIndex` with Neo4j backend.

📁 File Upload (小文件 ≤ 50KB):

+
    +
  • Supported formats: .txt, .md, .java, .py, .js, .sql, .json, .xml, .html, .csv
    • +
  • Maximum file size: 50KB (约50,000字符)
    • +
  • Files are automatically processed and added to the knowledge graph
    • +
  • File type is detected automatically from the extension
    • +
  • Large files will be rejected with suggestions
    • +
+ +

📂 Directory Processing (推荐用于大文件):

+
    +
  • 处理超过50KB的大文件的首选方法
    • +
  • 将大文件放在本地目录中，然后指定目录路径
    • +
  • Use comma-separated patterns like: *.txt,*.md,*.java
    • +
  • Supports nested directories (recursive search)
    • +
  • Each file is processed as a separate document, regardless of size
    • +
  • No file size restrictions for directory processing
    • +
+ +

🤖 MCP Client (程序化处理):

+
    +
  • Use uv run mcp_client for large file processing
    • +
  • Supports unlimited file sizes
    • +
  • Best for integration with AI assistants
    • +
  • Programmatic access to all knowledge graph features
    • +
+ +

🔧 Features:

+
    +
  • Real-time progress monitoring
    • +
  • Automatic task queue management
    • +
  • Error handling and retry mechanisms
    • +
  • Knowledge graph integration
