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 connections
Supports secure connections to a PostgreSQL database, including SSL encryption and connection pool management
Query execution
Executes SQL queries and returns results, supporting parameter binding and query history
Schema management
Obtains metadata information such as database table structures, field types, primary and foreign keys
Natural language interface
Generates SQL queries through natural language descriptions or interprets database schemas
Advantages
A unified secure access layer to avoid direct exposure of database credentials
A standardized interface simplifies multi-database management
Built-in query caching and history functions
Supports the intelligent function of converting natural language to SQL
Limitations
Adds an extra layer of network latency
Requires additional maintenance of the MCP server
Currently only supports the PostgreSQL database

How to use

Installation and deployment
Clone the repository, install dependencies, and configure environment variables
Start the service
Start in development mode or production environment
Connect to the database
Send a connection request through the SSE endpoint

Usage examples

Get the structure of the users table
Describe the structure and field information of the users table
Generate SQL to query recent orders
Generate SQL to query users who placed orders in the last 7 days based on a natural language description
