Postgres

This is a read-only PostgreSQL client that lets Claude query your databases safely. You set up connections in a JSON config file with descriptions like "user accounts and profiles" or "sales transactions," and Claude can auto-select the right database based on context. The security model is solid: connections are opened in read-only mode, query validation blocks anything that's not a SELECT, and there's a 30-second timeout plus 10,000 row limit to prevent runaway queries. The schema exploration commands (list tables, show structure) are genuinely useful for letting Claude understand your data model before writing queries. If you're doing data analysis or exploration with an AI assistant, this handles the boring connection plumbing while keeping your data safe from accidental writes.
