-SSE, and choose **OAuth** under **Authentication**. Save the server, then choose
-**Connect**. For manual configuration, add `auth: "oauth"` and open

-nanobot opens the server's authorization page and handles the callback through
-the gateway. The tools become available immediately when hot reload succeeds;
-otherwise the WebUI asks for a restart. OAuth tokens and dynamic client
-registration data are stored in the nanobot data directory under
-`auth/mcp.json`; they are not written to `config.json`. Removing the MCP server
-from Apps also removes its saved OAuth credentials. Normal gateway startup never
-opens a browser or registers a new OAuth client when credentials are
-missing—interactive authorization starts only after a user clicks **Connect**.
-
-For a remotely accessed WebUI, HTTPS is recommended. Configure
-`channels.websocket.publicWsUrl` with the browser-facing `wss://` endpoint so
-nanobot can register the matching HTTPS callback and finish automatically. A
-loopback WebUI may use HTTP. When a remote WebUI is served over plain HTTP,
-nanobot instead registers a localhost callback and asks you to paste the complete
-callback URL from the browser address bar after authorization.

-name collisions. Invalid manifests, components, nested skills, and escaping paths are ignored.

 Tool hints are the short progress messages shown when the agent calls tools (e.g. `$ cd …/project && npm test`). By default, these are truncated at 40 characters, which can make long commands hard to read.
