SQL Benchmarks Lab MCP Server

This platform is a specialized laboratory for testing SQL performance hypotheses. It transforms query tuning from intuition into a reproducible science. It runs locally over stdio via the published package.

People who work with benchmarks, dagster and duckdb and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.
