ChatGPT
Add an Odel module or gateway to ChatGPT in developer mode
ChatGPT connects to remote MCP servers through developer mode, available to Pro, Plus, Business, Enterprise, and Education accounts on the web. If you don't see the setting, your plan doesn't have it — nothing on the Odel side changes that.
The URL
https://mcp.odel.app/@odel/calculator-basicA worked example. Open this page from a module or gateway on Odel and it fills in with that address instead.
Adding it
Turn on developer mode in ChatGPT's settings, then create an app for the URL above. Choose OAuth as the authentication method — Odel signs you in with your Odel account rather than an API key.
OpenAI documents where the toggle lives and how the app is created in ChatGPT Developer mode.
Signing in
ChatGPT sends you to Odel to approve the module or gateway. Once approved, its tools can be toggled on per conversation.
If it doesn't connect
