Set Up Your MCP Dev Stack in Claude Code: GitHub, Postgres, Playwright, Filesystem

Schema-Grounded SQL Generator (with Tests and Explanations)
Generate correct SQL from plain-English questions by grounding the model in your real schema — with dialect awareness, assumptions, a query explanation, sanity checks and optional test data.
