description: Add AdCrunch to Claude as a custom connector, on claude.ai, Claude Desktop, and the mobile apps.
---

:::tip

AdCrunch is a **remote MCP server**. You install nothing. You add its URL to Claude as a custom connector, and you sign in once. The connector then works on claude.ai, in Claude Desktop, and in the Claude mobile apps.

:::

Custom connectors work on every Claude plan. The Free plan allows one custom connector.

## Install

**Free, Pro, Max**

1. **Open Connectors**

    On claude.ai or in Claude Desktop, go to **Customize → Connectors**.

2. **Add the connector**

    Click **+**, then **Add custom connector**. Enter the name `AdCrunch` and
    the URL `https://mcp.adcrunch.dev/mcp`. Leave **Advanced settings** empty,
    then click **Add**.

3. **Sign in**

    Click **Connect**. Your browser opens the AdCrunch sign-in. Sign in and
    approve the access.

**Team, Enterprise**

1. **An Owner adds the connector**

    An Owner or Primary Owner goes to **Organization settings → Connectors**,
    clicks **Add**, then **Custom**, then **Web**, enters the URL
    `https://mcp.adcrunch.dev/mcp`, and clicks **Add**.

2. **Each member signs in**

    Each member goes to **Customize → Connectors**, finds AdCrunch with the
    **Custom** label, and clicks **Connect**. The browser opens the AdCrunch
    sign-in. Sign in and approve the access.

The consent screen does not ask for an organization. Claude acts for the organization that is active in your most recent AdCrunch session. [Auth & scopes](/mcp/auth#which-organization-your-client-acts-for) explains how to choose it.

## Try it

In a new chat, click **+**, then **Connectors**, and turn on AdCrunch for that chat. Then ask: _"List my advertisers."_ Claude 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.

:::warning[Approve each change yourself]

Claude asks before it calls a tool, and you can answer **Allow always**. Keep that answer for the tools that only read. A tool such as `meta_update_budget` changes what runs on your ad account, so approve each call. Research mode calls connector tools without asking, so do not use AdCrunch's write tools in Research mode.

## Troubleshooting

:::warning[AdCrunch does not show in the chat]

A connector is turned on for each chat. Click **+**, then **Connectors**, and check that AdCrunch is on. If the connector shows an error, open **Customize → Connectors**, remove AdCrunch, and add it again.
