PostgreSQL MCP Server

This MCP server provides secure, read-only access to PostgreSQL databases through the Model Context Protocol, enabling AI assistants and applications to query and retrieve data without write permissions. Developed by Anthropic in TypeScript, it establishes a controlled interface for database interactions, allowing language models to access structured information while maintaining data integrity through read-only enforcement. The server bridges the gap between AI systems and relational databases, making enterprise data accessible for analysis, reporting, and intelligent decision-making workflows.

The PostgreSQL MCP server supports comprehensive query execution capabilities including SELECT statements, table schema inspection, and database metadata retrieval. It enables developers to configure connection parameters, manage authentication securely, and specify which databases and tables should be accessible through the MCP interface. The implementation provides structured responses that integrate seamlessly with Claude and other MCP-compatible clients, facilitating natural language queries against database contents while preventing accidental or malicious data modifications.

This server is compatible with any client implementing the Model Context Protocol, including Claude for enterprise deployments, custom AI applications, and development tools. Typical use cases include enabling AI assistants to answer questions about business data, automating report generation from database queries, supporting data-driven research workflows, and creating intelligent customer service bots that access product or account information. Organizations can deploy this server in secure environments to leverage AI capabilities while protecting sensitive database operations.
