How to connect duelgo to ChatGPT

ChatGPT supports custom MCP connectors on paid plans via developer mode. The OpenAI interface evolves fairly quickly — if yours looks different, look for the Connectors section in the settings.

  1. Turn on developer mode

    In ChatGPT, open Settings → Apps & Connectors → Advanced settings and turn on Developer mode.

  2. Create the connector

    In the connectors section, choose Create / add a connector: name “duelgo”, MCP server URL https://www.duelgo.fun/mcp, authentication OAuth. Save.

  3. Sign in

    When you create the connector (or use it for the first time), ChatGPT sends you to the duelgo sign-in — sign in and confirm the consent.

  4. Use the connector in a chat

    In a conversation, pick your duelgo connector in the tools menu (the + icon) and type, for example, “List my duelgo chats.”

Good to know

Availability of custom connectors varies by plan (Plus/Pro/Business) and region; in company workspaces it may need to be enabled by an administrator.

You can revoke access by deleting the connector in the ChatGPT settings.
