What is PostgreSQL Model Context Protocol (PG-MCP) Server?

PG-MCP is a server implementation of the Model Context Protocol (MCP) for PostgreSQL databases. It provides a comprehensive API for AI agents to discover, connect to, query, and understand PostgreSQL databases through MCP’s resource-oriented architecture. The server includes multi-database support, rich catalog information, built-in extension context (e.g., PostGIS, pgvector), and query explanation tools.

How to use PostgreSQL Model Context Protocol (PG-MCP) Server?

Install via Docker (docker-compose up -d) or manually (uv sync, then python -m server.app). Use the provided test scripts (test.py and example-clients/claude_cli.py) to verify functionality. For AI agents, use the server’s tools (connect, disconnect, pg_query, pg_explain) and explore schema resources via pgmcp://{conn_id}/ URIs.
