querybridge-mcp

A Model Context Protocol (MCP) server connecting Claude Code and other MCP clients to MySQL/MariaDB databases. Version 0.11.1 (2025) is stable, with active development on GitHub. It provides 39 tools across schema introspection, querying, profiling, ERD generation, stored programmability, diagnostics, and cross-database diffing, plus 2 resources and 4 prompts. Key differentiators vs alternatives: built-in SSH tunnel with host fingerprint pinning, SSL/TLS support, read-only-by-default with per-connection write control, client-side blocking of LOAD DATA LOCAL INFILE, secrets via env/file indirection, MCP signal cancellation mapping to KILL QUERY, and a CLI for managing connections. Ships TypeScript types, requires Node >=20, and supports both local stdio and remote Streamable HTTP transport with bearer auth.
