What is the PostgreSQL MCP Server?

The PostgreSQL MCP Server is a middleware service that allows applications to interact with a PostgreSQL database through the standardized MCP protocol. It encapsulates complex operations such as database connection, query execution, and schema management, and provides a simple and easy-to-use API interface.

How to use the PostgreSQL MCP Server?

By sending HTTP requests to the MCP server endpoint and configuring the database connection information, you can perform operations such as executing queries and obtaining table structures. It supports the Server-Sent Events (SSE) real-time communication protocol.

Use cases

Suitable for web applications, data analysis tools, and automated workflows that require secure access to a PostgreSQL database, especially in scenarios where multiple database connections need to be managed uniformly.

Main features

Database connectionsSupports secure connections to a PostgreSQL database, including SSL encryption and connection pool management

Query executionExecutes SQL queries and returns results, supporting parameter binding and query history

Schema managementObtains metadata information such as database table structures, field types, primary and foreign keys

Natural language interfaceGenerates SQL queries through natural language descriptions or interprets database schemas
