Give your AI complete control over PostgreSQL databases. Execute complex queries, manage schemas, analyze performance, and automate database operations with natural language commands - the most powerful database MCP for enterprise applications.
PostgreSQL MCP is a Model Context Protocol server that enables AI assistants like Claude to interact with PostgreSQL databases through natural language. It supports all SQL operations including SELECT, INSERT, UPDATE, DELETE, schema management, transactions, performance optimization, and advanced features like CTEs and window functions. Enterprise-grade security with SSL/TLS encryption, role-based access control, and connection pooling.
PostgreSQL MCP transforms your AI assistant into a database administrator, data analyst, and performance engineer all rolled into one. Instead of writing complex SQL queries, debugging syntax errors, or manually optimizing database performance, you can simply tell your AI what you need in plain English, and it handles everything from simple SELECT statements to complex migrations and performance tuning.
