Connect your Postgres database to Claude

If your business already runs on a Postgres database, you don't need another OAuth app — Synquil connects with a read-only connection string and gives Claude safe, validated access to query it directly.

How it works

  1. Connect with a connection string. Use a read-only database role — Synquil never requests write access, and connections to internal or private network addresses are blocked.
  2. Synquil structures your tables. Your existing schema is mapped into a queryable model that stays in sync on a recurring schedule.
  3. Add Synquil as a connector in Claude. Paste your MCP URL into Claude's connector settings and authorize once.
  4. Query your data in plain English. Every query Claude runs is validated as SELECT-only before it executes — nothing in your database can be written or deleted through Synquil.

Example questions you can ask Claude

“How many new signups did we get this week, by day?”
“What is the average order value for repeat customers?”
“List the 10 largest accounts by row count.”
“Show month-over-month growth in the orders table.”

Where this is most useful

Technical founders and teams running their own product database get the most value — no need to build a custom MCP server from scratch just to let Claude read your data safely.

Let Claude query your own database, safely.
