What is PgSQL MCP Server?
PgSQL MCP Server is a tool server built on the FastMCP framework, which allows users to interact with the PostgreSQL database through MCP calls. The server uses the SQLAlchemy and asyncpg libraries to provide efficient asynchronous database operation capabilities.How to use PgSQL MCP Server?
After installation, simply configure the database connection string (DSN) to start the server. You can use the MCP Inspector tool for visual debugging and test calls.Applicable scenarios
Suitable for application development scenarios that require efficient interaction with the PostgreSQL database, especially projects that require asynchronous operations and transaction security.Main features
Asynchronous and efficient operationA fully asynchronous and high-performance PostgreSQL driver implemented based on asyncio and asyncpg
Transaction safetyAll DDL, DML, and DCL operations are executed within a transaction, with error handling and rollback mechanisms
Easy deploymentThe server can be started through a simple command-line interface
Advantages and limitations
Advantages
High-performance asynchronous operations, suitable for high-concurrency scenarios
Provides transaction safety guarantees to ensure data consistency
Simple and easy-to-use deployment method
Limitations
Only supports the PostgreSQL database
Requires a Python 3.8+ environment
May require a certain learning cost for non-technical personnel
How to use
Installation
Ensure that Python 3.8+ is installed. It is recommended to use uvx for installation.
