This MCP server provides access to MySQL databases through SSH tunnels, enabling Claude and other LLMs to inspect database schemas and execute SQL queries securely. It is a Node.js-based MCP server with support for multiple databases and per-project configurations, including a Claude Code-optimized fork with SSH tunnel integration and auto-start/stop hooks for seamless tunnel management. The server implements DDL support by enabling the MYSQL_DISABLE_READ_ONLY_TRANSACTIONS flag, enabling CREATE TABLE and related statements when allowed. It supports multi-database mode by omitting MYSQL_DB so the LLM can query any accessible database, with queries requiring fully-qualified table names. It introduces schema-specific permissions to control INSERT, UPDATE, DELETE, and DDL operations on a per-database basis. The configuration is driven by environment variables, with options for connection pooling, timeouts, caching, rate limits, SSL, logging, and remote operation. The README also covers running from a local clone, installing via Smithery, and remote mode operation, including guidance for Claude Desktop integration and CLI usage. Overall, the MCP server emphasizes secure, auditable access to MySQL for LLM-assisted schema inspection and data manipulation within defined boundaries.
