 ## Tools hot updates
-Run the MCP server separately from the main backend. Use `cache_ttl: 0` in the
-MCP tooling config to disable tool list caching.
+Local function tools are managed via the same backend (port 6400).
 
 Endpoints:
-- List tools: `GET http://127.0.0.1:8010/admin/tools/list` (returns `source` and `call_methods`)
-- Upload tool: `POST http://127.0.0.1:8010/admin/tools/upload`
-- Reload tools: `POST http://127.0.0.1:8010/admin/tools/reload`
+- List local tools: `GET http://127.0.0.1:6400/api/tools/local`
+- Create/overwrite local tool file: `POST http://127.0.0.1:6400/api/tools/local`
 
-Wiring rules (from `source`):
-- `local_tools`: can wire via `tooling.type: function` or `tooling.type: mcp_remote`.
-- `mcp_tools`: wire via `tooling.type: mcp_remote` only.
