# Claude & ChatGPT Connector

> Run AI Calling campaigns straight from Claude or ChatGPT by connecting hyzl as a Model Context Protocol connector.

Connect hyzl to **Claude** or **ChatGPT** and run your AI Calling campaigns by chatting. You can check your remaining calls, review past calls and lead warmth, draft a campaign, and launch it. You never leave the assistant. It works through the open [Model Context Protocol (MCP)](https://modelcontextprotocol.io) standard. That is why the same connection works in Claude (web and desktop), ChatGPT, and any other MCP-compatible client.

<Note>
  The connector is available on **paid hyzl plans**. Everything runs through your normal hyzl account, so your billing, consent, and calling-window rules always apply. The assistant can never bypass them.
</Note>

## How it works

You add one connector URL to Claude or ChatGPT and sign in to hyzl once to approve it. After that, you can ask the assistant to work with your campaigns in plain language. The assistant confirms each action that places real calls before it runs.

The connector URL is:

```
https://api.atllas.com/api/mcp
```

## Connect to Claude

  Custom connectors are available on Claude's paid plans, under **Settings → Connectors**.

You are connected. Start a chat and ask the assistant to list your campaigns.

## What you can ask for

Once connected, the assistant can:

| Ask for…                                                        | What it does                                                                                  |
| --------------------------------------------------------------- | --------------------------------------------------------------------------------------------- |
| "How many calls do I have left?"                                | Shows your plan limit and remaining calls this billing period                                 |
| "When does my billing period reset?"                            | Shows your billing period's start, end, and reset date                                        |
| "How did my calling do this month?"                             | Account-wide analytics: answered, missed, qualified leads, and follow-up emails over a window |
| "Who exactly will this campaign call?"                          | Reviews a draft campaign's contact list before launch                                         |
| "List my campaigns"                                             | Lists your AI Calling campaigns and their results                                             |
| "Show me the last few calls on \<campaign>"                     | Pulls calls with transcripts, summaries, and lead warmth                                      |
| "Who should I follow up with?"                                  | Surfaces your hot and warm leads with open follow-ups                                         |
| "Create a campaign that calls these people and asks about \<X>" | Drafts a new campaign from your instructions                                                  |
| "Launch it"                                                     | Starts the campaign and begins placing calls                                                  |
| "Place a preview call to my phone"                              | Places a single real test call so you can hear the campaign                                   |
| "Add \<number> to my Do Not Call list"                          | Views and manages your account's Do Not Call list                                             |

Anything that places a real call (previewing, creating, or launching a campaign) is confirmed by the assistant before it runs.

## Permissions

When you approve the connector, you grant it access to:

* **See your campaigns and their results**
* **See your calls, transcripts, and lead warmth**
* **See your account analytics and billing period**
* **Create and launch calling campaigns on your behalf**
* **Place preview (test) calls on your behalf**
* **View and manage your Do Not Call list**

By default the connector is granted full access so you can do everything from the assistant. The connection acts as you, and every call still counts against your plan and obeys your calling-window and consent settings.

## Fix common problems

* **"This token is not authorized" / nothing happens after connecting**. Remove the connector and add it again, making sure the URL is exactly `https://api.atllas.com/api/mcp`.
* **"Connecting an AI assistant requires a paid hyzl plan"**. The connector is a paid feature. Upgrade your plan and try again.
* **The assistant cannot see your campaigns**. Make sure you completed the **Allow** step in hyzl; if you closed that window, start the connect flow again.

## Disconnect the connector

To disconnect, remove the hyzl connector from your assistant's settings:

* **Claude:** Settings → Connectors → hyzl → Remove.
* **ChatGPT:** Settings → Connectors → hyzl → Remove.

This immediately stops the assistant from accessing your hyzl account.
