pgsql-mcp-server 1.4.0

PostgreSQL MCP Server

PgSQL MCP Server

A powerful tool server based on the Model Context Protocol (MCP), enabling interaction with PostgreSQL databases via MCP calls.

---

🚀 Overview

This project is built on the FastMCP framework and leverages the SQLAlchemy and asyncpg libraries to deliver high-performance asynchronous database operations, ensuring efficiency and responsiveness when handling database requests.

✨ Key Features

• Asynchronous & Efficient: Fully asynchronous implementation based on asyncio, utilizing asyncpg for a high-performance asynchronous PostgreSQL driver.
• Transactional Safety: DDL, DML, and DCL operations are executed within transactions with error handling and rollback mechanisms.
• Easy Deployment: Start the server with a simple command line interface.

📦 Installation

Ensure you have Python 3.8+ installed. Installation via uvx is recommended:

uvx pgsql-mcp-server --dsn postgresql://user:password@localhost:5432/db

🔍 Preview and Debugging

You can use the official MCP Inspector tool to visually inspect the tools provided by this server, view their parameters and descriptions, and perform test calls directly.

npx @modelcontextprotocol/inspector uvx pgsql-mcp-server --dsn "postgresql://user:password@host:port/database"

This will start a local web service. Open the provided URL in your browser to begin debugging.
