Connect PostgreSQL to AI assistants: schemas, tables, SQL and database health.
Part of the Insightful Pipe MCP Server Collection — use PostgreSQL from Claude, ChatGPT, Cursor, and other AI assistants through the Model Context Protocol (MCP).
https://postgresql.insightfulmcp.com/
PostgreSQL MCP is a remote Model Context Protocol server hosted by InsightfulPipe. Browse schemas and tables, inspect columns, run SQL, and read pg_stat insights against your own PostgreSQL database. Read vs. read-write is decided by the GRANT/REVOKE privileges on the role this connector logs in as.
- Copy the MCP Server URL:
https://postgresql.insightfulmcp.com/ - Open Claude Connectors Settings
- Scroll to the bottom and click Add custom connector
- Paste the URL and click Add
- Click Connect on the connector to start authorization
- Click Authorize access in the browser to complete the connection
Custom MCP servers are added through ChatGPT's Developer mode. Availability depends on your ChatGPT plan, and workspace admins may need to allow it.
- Turn on Developer mode in ChatGPT settings
- Create a new app for a remote MCP server and paste the URL:
https://postgresql.insightfulmcp.com/ - Authorize with your InsightfulPipe account
See OpenAI's guide: Developer mode and MCP apps in ChatGPT
claude mcp add --transport http postgresql https://postgresql.insightfulmcp.com/Add the server to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project):

You decide what AI agents can do with each connected account:
- Turn individual actions on or off for every connected account, so agents only see the actions you allow.
- Connect as Read-only or Read & Write. A read-only connection can only enable read actions.
- Destructive actions stay off by default. Actions such as deletes are disabled until an admin enables them.
- Team access per account. Restricted team members only use the accounts they are granted, with the read actions enabled on them.
"List the tables in the public schema"
"Show the schema of the orders table"
"Check my database health"
