description: 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.

:::

:::info[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, go to the [Quickstart](/quickstart#ten-minutes-start-to-finish) for a first question and a first change.

## Troubleshooting

:::warning[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.
