Postgres MCP Server
The Postgres MCP Server lets your AI connect directly to your PostgreSQL database — instead of writing SQL, you just tell the AI "who were the top 10 customers by revenue last month" and it queries the tables and returns the result.
For developers, this removes the back-and-forth of opening a DB client, writing SQL, and pasting results back into the AI. Once installed, your database becomes part of the AI's context.
Install / Connect
# No npm package — install from source.
# See the repo's README for the exact command:

Why use it
Good for: developers and data analysts who want the AI to help explore data, generate reports, or debug production data issues.
Before connecting: your connection string holds sensitive credentials — use a read-only account for production databases. Review the maintenance signals below, then test compatibility and security in your own environment.

Frequently Asked Questions
Will the Postgres MCP Server modify my data?
It depends on the permissions of the database account you give it. To stay safe, use a read-only account for production so the AI can only query, not change data.
Which AI clients are supported?
Claude Desktop, Claude Code, Cursor, and VS Code all work with MCP. See the installation section below for the config.
