MCP PostgreSQL Server

Example Use Cases

• 1

  Inspect database table schemas programmatically to understand column types and relationships before constructing queries.

• 2

  Generate and execute safe, read-only SQL queries against a PostgreSQL instance without risking data modification.

• 3

  Integrate with developer tools (like Cursor) to enable interactive database exploration and query assistance using LLM prompts.

Description

This server auto-discovers PostgreSQL table schemas and exposes them as JSON resources, and it provides a tool to execute SQL queries inside READ ONLY transactions with automatic rollback. It is designed to let agents inspect database structure and run safe, read-only queries for analysis, join generation, and data exploration. The project includes Docker Compose with a sample database and integration instructions for the Cursor editor to simplify local testing and usage.
