FAQ from MCP Server for MySQL based on NodeJS

How does read‑only access work?

All queries are executed inside a READ ONLY transaction. The server enforces read‑only semantics and supports prepared statements for parameterised queries.

What are the runtime dependencies?

You need Node.js and a MySQL server (supports caching_sha2_password and mysql_native_password). The server can be installed globally via npm or run via npx.

What environment variables must I set?

At minimum: MYSQL_HOST, MYSQL_PORT, MYSQL_USER, MYSQL_PASS, and optionally MYSQL_DB. Advanced options for pooling, timeouts, caching, rate limiting, SSL, and logging are also available.

Does the server support SSL/TLS?

Yes. Set MYSQL_SSL to true to enable encrypted connections.

How do I troubleshoot connection issues?

Verify MySQL is running, check credentials and permissions, and ensure the correct authentication plugin is used. For MySQL 8.0+ you may need a user created with mysql_native_password. Use Smithery diagnostics (smithery diagnose) or manual log checking.
