Connect Postgres to Claude with MCP | Peliqan

Connect Postgres to Claude, ChatGPT, Cursor or any MCP-compatible AI assistant in minutes with Peliqan’s no-code Peliqan MCP server. In this tutorial, you enable the Postgres MCP server in Peliqan, so your AI can query live Postgres (PostgreSQL) data – schemas, tables and views – without manual exports or API setup. For a deeper overview, see the Postgres MCP page.

How to connect Postgres to Claude

1. 1First, connect Postgres in Peliqan. Add the Postgres connector and sign in once. Peliqan then stores your credentials and keeps the data in sync.
2. 2Next, add Peliqan to Claude. In Claude, go to Settings → Connectors → Add custom connector. Give it a name, paste https://mcp.eu.peliqan.io/mcp as the URL, click Add, then log in and approve. ChatGPT, Cursor, Gemini and other MCP clients work the same way: add the same endpoint in their connector or MCP settings.
3. 3Finally, just ask. Question your Postgres data in plain language, and your AI assistant acts on the answers.

What you can do with Postgres + AI

• Ask questions about your Postgres data in plain English, then get live answers in your AI chat
• Explore schemas, tables and views without exporting a single CSV
• Combine Postgres with the other tools you connect through Peliqan, all in one conversation
• Let your AI act on the data: draft, update or create records wherever you enable write access

Example prompts once Postgres MCP is enabled

• “Show the schema of my orders table in Postgres and preview 10 rows.”
• “Write a query that returns new customers per week.”
• “Which tables are largest by row count?”

About the Postgres MCP server

Model Context Protocol (MCP) is the open standard that lets AI assistants work with external tools and data. In short, the Peliqan Postgres MCP server is a hosted, MCP-compliant endpoint that exposes your Postgres data to AI clients such as Claude, ChatGPT, Cursor and Gemini. As a result, you install nothing and maintain nothing on your side. Because Peliqan holds your Postgres connector login rather than your AI, access stays governed and secure.

Works with Claude, ChatGPT, Cursor and more

The Peliqan Postgres MCP connector works with Claude, Claude Code, ChatGPT, Gemini, Cursor and VS Code (Copilot), as well as any other MCP-compatible client. As a result, you can switch AI tools whenever you like. To learn more, visit the Peliqan MCP server page, or browse all Peliqan connectors.
