Add MCP tools
MCP servers provide external tools over stdio or HTTP. Configure services you understand and use a harmless tool call to verify setup before connecting sensitive work.
- Open Settings → MCP and choose Add Server, or import an existing compatible configuration.
- Review the executable and arguments for a stdio server, or the endpoint and authentication for an HTTP server. Importing configuration does not establish that the service is trustworthy or compatible.
- Connect the server and inspect its discovered tools. Confirm JUDAS allows its transport; restricted modes block external MCP processes.
- Enable tools in the chat and select the needed server through the composer’s + menu.
- Ask for a small read-only action. Review the exact arguments in the approval dialog, then allow or deny it. Inspect its result in the transcript.
MCP approvals are independent of native Herder file/command grants. Remembered approval binds to the configured server/tool authority, and an external server may impose additional rules or its own approval queue.
If a call times out, its outcome may be unknown. Inspect the affected service/files and reconnect deliberately before retrying. GOAT does not execute tool markup printed as ordinary text. See Troubleshooting and the connection reference.
