Refactor safe-inputs MCP server bootstrap to eliminate duplication

[Copilot]

The safe-inputs server startup logic was duplicated between stdio and HTTP transport implementations (~70 lines), creating maintenance burden and drift risk.

Changes

• New module: safe_inputs_bootstrap.cjs

  • bootstrapSafeInputsServer() - config loading, base path resolution, tool handler loading
  • cleanupConfigFile() - secure config file deletion

• Updated: safe_inputs_mcp_server.cjs and safe_inputs_mcp_server_http.cjs

  • Use shared bootstrap functions
  • Retain transport-specific initialization (stdio vs HTTP)

• Registration: Added bootstrap module to pkg/workflow/js.go embed directives

Example

Before - duplicated in both files:

const config = loadConfig(configPath);
const basePath = path.dirname(configPath);
const tools = loadToolHandlers(server, config.tools, basePath);
// ... cleanup logic

After - centralized:

const { config, tools } = bootstrapSafeInputsServer(configPath, logger);
cleanupConfigFile(configPath, logger);

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/user

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Analysis of commit 8d26b38

Assignee: @copilot

Summary

The safe-inputs server startup logic is duplicated between the stdio entrypoint and the HTTP entrypoint. Both modules load the config, resolve handler paths, register tools, and delete the config file with nearly identical code paths, increasing maintenance risk when adding validation or telemetry.

Duplication Details

Pattern: Repeated safe-inputs server creation/config loading

• Severity: Medium
• Occurrences: 2 implementations
• Locations:
  • pkg/workflow/js/safe_inputs_mcp_server.cjs (lines 49-88)
  • pkg/workflow/js/safe_inputs_mcp_server_http.cjs (lines 37-129)
• Code Sample:

  // safe_inputs_mcp_server.cjs
  const config = loadConfig(configPath);
  const basePath = path.dirname(configPath);
  const server = createServer({ name: serverName, version }, { logDir });
  const tools = loadToolHandlers(server, config.tools, basePath);
  tools.forEach(tool => registerTool(server, tool));
  // delete config file
  
  // safe_inputs_mcp_server_http.cjs
  const config = loadConfig(configPath);
  const basePath = path.dirname(configPath);
  const server = new MCPServer({ name: serverName, version }, { capabilities: { tools: {} } });
  const tools = loadToolHandlers(tempServer, config.tools, basePath);
  tools.forEach(tool => server.tool(tool.name, tool.description, tool.inputSchema, handler));
  // delete config file

Impact Analysis

• Maintainability: Changes to config parsing, logging, or deletion must be applied twice, risking drift between transports.
• Bug Risk: Validation differences (logDir handling, required fields) can cause HTTP and stdio modes to behave inconsistently.
• Code Bloat: Extra bootstrap logic increases surface area for future fixes.

Refactoring Recommendations

1. Extract shared safe-inputs server factory

   • Create a single helper (e.g., createSafeInputsServer(configPath, options)) returning the configured server and tools; both stdio and HTTP entrypoints should consume it.
   • Estimated effort: 3-4 hours.
   • Benefits: One code path for config handling, logging, and cleanup.

2. Align transport selection

   • Parameterize transport (stdio vs HTTP) while reusing the shared registration/cleanup logic.
   • Estimated effort: 2 hours.
   • Benefits: Consistent behavior regardless of transport.

Implementation Checklist

• Review duplication findings
• Prioritize refactoring tasks
• Create refactoring plan
• Implement changes
• Update tests
• Verify no functionality broken
