Cursor MCP tools not showing

Cursor MCP tools may not appear because the server is not connected, the configuration is invalid, or Cursor failed to start the server. Verify the connection status, validate the config, and reload Cursor's MCP servers.

Confirm the server shows as connected in Cursor's MCP view. If it does not, validate the config JSON and the transport. A remote server must be reachable; a local server must launch successfully.

Cursor lets you reload or reconnect servers. After editing configuration, reload the server list so Cursor re-reads the config and restarts the server.
