A FastMCP-powered Model Context Protocol server that gives AI assistants (Claude, Cursor, etc.) full, structured access to a PostgreSQL database — no SQL knowledge required from the user.
PostgreSQL MCP Server (Model Context Protocol) is an MCP project maintained in the vivekmalipatel/postgres_mcp_server repository. The maintainer describes its purpose as “A FastMCP-powered Model Context Protocol server that gives AI assistants (Claude, Cursor, etc.) full, structured access to a PostgreSQL database — no SQL knowledge required…”. Read the project documentation for the complete scope.
The project provides a local client configuration using /absolute/path/to/.mcp/bin/uv. Follow the repository’s build and installation steps before copying it, and replace example paths with the paths on your own computer.
The example declares POSTGRES_HOST, POSTGRES_PORT, POSTGRES_USER, POSTGRES_PASSWORD, POSTGRES_DB. Secret-looking values have been replaced with placeholders. Required and optional labels are shown only when the documentation states them.
