ChatGPT

Tested on production on 2026-10-03.

1. In ChatGPT, open Settings › Apps & Connectors, turn on Developer mode under Advanced settings, then choose Create.
2. Name it HeaderHawk, give it the URL https://mcp.us.headerhawk.com/mcp, choose OAuth for authentication, and create it.
3. HeaderHawk’s sign-in page opens: sign in, then choose Authorize on the screen that asks to connect HeaderHawk with ChatGPT.
4. In a conversation, add the HeaderHawk connector and ask, for example, “Which scripts on our payment page have known vulnerabilities?”

Developer mode may depend on your ChatGPT plan.

The consent screen shows no warning: ChatGPT identifies itself with a client metadata document on chatgpt.com, a host HeaderHawk verifies.

Disconnecting

Delete the connector in ChatGPT, and disconnect it under Settings › API keys › Connected assistants in HeaderHawk. See Connect an AI assistant.
