TheRaLabs/legion-mcp
Multi-Database MCP Server, from Legion AI, gives an assistant access to several database engines behind one consistent set of tools, built on the Legion Query Runner. Rather than a server per engine, one server connects to PostgreSQL, MySQL, SQL Server and the other backends the query runner supports, so the same tool calls work regardless of which database is behind them and there is no per-engine client library to learn. Schema discovery is automatic — the server enumerates tables, columns and types without manual configuration or mapping, which is what lets a model inspect an unfamiliar database and then write a query that matches its actual structure instead of a guessed one. Query execution returns results in a form intended for model consumption rather than raw driver output. The project is Python, built on the MCP Python SDK. Two things are worth noting from the README: it is published by Legion AI as a component of a larger commercial analytics product, and the maintainers invite requests for additional database support, which suggests coverage is driven by demand rather than complete. The audience is analysts and developers working across a heterogeneous database estate who want one MCP server rather than a separate configuration entry for every engine.
