FAQ from CockroachDB MCP Server

How do I connect to a CockroachDB database?

Use the connect_database or initialize_connection tool with the JDBC URL, username, and password.

What if I encounter connection problems?

Check the server log file logs/cockroachdb_mcp.log for details. Common issues include connection refused, authentication failed, and connection timeout.

Does the server handle special characters in passwords?

Yes, it uses psycopg2 which automatically handles special characters such as @, %, and & without requiring additional URL encoding.

How does the server prevent connection timeouts?

The server enables TCP keep‑alive by default: it sends keepalive packets after 30 seconds of idle time, every 10 seconds, and gives up after 5 attempts.

What transport does the server use?

The server runs as a subprocess via the uv command and communicates with Cursor through the MCP stdio transport. Authentication is passed as configuration parameters.
