Required runtime environment for the MCP server, enabling the execution of database management operations through a Node.js application.
Provides PostgreSQL database management capabilities, including analyzing existing PostgreSQL setups, implementation guidance, debugging database issues, managing schemas, migrating data, and monitoring database performance.
PostgreSQL MCP Server
A Model Context Protocol (MCP) server that provides direct PostgreSQL database query execution capabilities. This server enables custom SQL query execution against PostgreSQL databases with support for parameterized queries and configurable timeouts. This project is designed specifically for use with the Cursor IDE.
