ChatGPT support in preview

By Team Gentility · Sep 20, 2025

We now expose an early integration path for using ChatGPT with Gentility. Today, Claude is fully supported and production-ready. ChatGPT support is in preview - MCP support on the ChatGPT side is very new and still evolving. Expect changes and the occasional rough edge as things stabilize.

What "preview" means

  • You'll need to enable Developer mode to use Gentility.

How to try it

  1. Install and run the Gentility agent on your server or workstation.
  2. Enable your MCP target(s) and verify access policies.
  3. In ChatGPT (Plus), enable Developer Mode and open Connectors.
  4. Add a new connector pointing to the Gentility MCP endpoint at
    https://mcp.gentility.ai/
  5. Enable the connector in your chat and send a simple query.

Requirements

  • ChatGPT Plus or better.
  • A Gentility account and API key for your agent.

Known limitations

  • Reliability is still improving, with some systems still prone to error and may require many retries, or not work at all. We expect this to stabilise over the coming weeks as MCP support in ChatGPT matures.

What's next

We're collaborating with the ecosystem to harden MCP support, improve resilience, and graduate ChatGPT from experimental as soon as it's ready.
