Task Summary

• What to build: Add PATCH /:id/image route in apps/backend/src/routes/categories.ts and register/handle update_category_image tool in apps/mcp-server/index.ts.
• Success criteria: API route works, MCP tool works, builds pass without TypeScript compilation errors.
• Interface contracts: apps/backend/src/routes/categories.ts & apps/mcp-server/index.ts
• Code layout: apps/backend/src, apps/mcp-server/src

Key Decisions Made

• Added a PATCH /categories/:id/image route in the backend rather than using PUT to make updates fine-grained and avoid sending full model data.
• Added update_category_image tool schema and handler in the MCP server.
• Wrote integration tests verifying the PATCH route directly via Elysia and testing the MCP server via JSON-RPC stdio.

• Files modified:
  • apps/backend/src/routes/categories.ts: Added PATCH route.
  • apps/mcp-server/index.ts: Added MCP tool registration and case handler.
