An MCP server for Text2SQL: transforms natural language into SQL using graph schema understanding.
An MCP server for Text2SQL: transforms natural language into SQL using graph schema understanding.
QueryWeaver is an open-source Text2SQL tool that converts plain-English questions into SQL using graph-powered schema understanding. It helps you ask databases natural-language questions and returns SQL and results.
QueryWeaver exposes a small REST API for managing graphs (database schemas) and running Text2SQL queries. All endpoints that modify or access user-scoped data require authentication via a bearer token. In the browser the app uses session cookies and OAuth flows; for CLI and scripts you can use an API token (see tokens routes or the web UI to create one).
Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
