Multi-Postgres

About

This tool revolutionizes how AI clients interact with PostgreSQL databases by allowing a single Model Context Protocol (MCP) server instance to manage an unlimited number of databases. Unlike the official MCP server, which requires a separate process for each database, Multi-Postgres simplifies your setup, offering a centralized configuration with hot-reload capabilities. It enhances security and project isolation through read-only queries and `--label` filtering, ensuring AI clients access only designated databases safely. This efficiency makes it an indispensable tool for developers working with multiple projects and their respective PostgreSQL instances, streamlining AI integration with database operations.

Key Features

• Ensures query safety by enforcing read-only transactions for all database operations.
• Provides per-project database isolation using a `--label` filter for AI clients.
• Compatible with various MCP-enabled AI clients, including Claude Code, Cursor, Windsurf, and Cline.
• 1 GitHub stars
• Manages unlimited PostgreSQL databases from a single server process.
• Hot-reloads configuration changes instantly without requiring a server restart.

Use Cases

• Managing multiple PostgreSQL databases for diverse projects with a single AI-accessible server.
• Streamlining database interaction for AI development tools like Claude Code and Cursor across various environments.
• Enabling secure, read-only AI access to specific project databases via `--label` isolation.
