ChatGPT

Install AdCrunch as a custom MCP connector in ChatGPT.

Tip

AdCrunch is a remote MCP server — there’s nothing to install locally. You add it as a custom connector and complete an OAuth flow.

Plan + developer mode required

Custom MCP connectors require a paid ChatGPT plan, and full tool access requires developer mode, which OpenAI labels beta — the exact menus may shift as ChatGPT evolves.

Install

  1. Enable developer mode

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

  2. Create the connector

    Back in Settings → Connectors, click Create. Fill in:

    • Name: AdCrunch
    • MCP server URL: https://mcp.adcrunch.dev/mcp
    • Authentication: OAuth

    Save, then complete the OAuth consent — sign in and pick the organization you want to expose to this client.

  3. Use it in a chat

    In a new conversation, open the + / tools menu, choose Developer mode, and enable the AdCrunch connector for that chat.

Try it

Ask ChatGPT: “List my advertisers.” It calls list_advertisers and reads back the result.

If that works, jump to the recipes.

Troubleshooting

Connector not callable in chat

Custom connectors must be enabled per conversation — check the tools menu. If the connector fails to create, re-check the URL is exactly https://mcp.adcrunch.dev/mcp and that developer mode is on.
