MySQL MCP Server

MySQL MCP Server is an open-source Model Context Protocol server that provides AI assistants with secure, structured access to MySQL databases. It enables LLMs like Claude to inspect database schemas, execute SQL queries, and analyze data through a controlled interface with built-in safety mechanisms. The server exposes database tables as MCP resources with full schema information including column names, data types, indexes, constraints, and foreign key relationships. Query execution supports read-only SELECT statements by default, with optional write operations (INSERT, UPDATE, DELETE) that can be individually enabled through environment variables. Security features include SQL injection prevention via prepared statements, query whitelisting and blacklisting, rate limiting, query complexity analysis, and connection encryption. Performance is handled through connection pooling, query result caching, large result set streaming, and execution plan analysis using EXPLAIN and EXPLAIN ANALYZE. The server works with Claude Desktop, VS Code, and other MCP clients, connecting to any MySQL instance through standard environment variable configuration. Multiple implementations exist in both Node.js and Python, making it adaptable to different deployment environments.
