A community MCP server that lets Claude query a PostgreSQL database and inspect its schema. By default it runs read-only, so the model can answer questions about your data and draft queries without the risk of mutating anything.
Why it matters
It turns "explain this data" and "write the query for X" from copy-paste chores into direct conversation — Claude sees the real schema and returns queries that actually run. A common building block for analytics and internal-tooling agents.
Good to know
- Read-only by design; grant write access deliberately if you need it.
- Schema introspection means Claude doesn't guess table or column names.
- Works well alongside the Filesystem server for report-generation workflows.
