**English** | [简体中文](./README_zh.md)

**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 3.10+ installed. Recommendation:

### Using uv (Recommended)

```bash
uv tool install pgsql-mcp-server
```

Then run it:
```bash
pgsql-mcp-server --dsn "postgresql://user:password@localhost:5432/db"
```

Or run directly without installation:
```bash
uvx pgsql-mcp-server --dsn "postgresql://user:password@localhost:5432/db"
```

### Using pip

```bash
pip install pgsql-mcp-server
```
