# Use CallForMe in Grok

> On grok.com, open Connectors, click New Connector, choose Custom and paste https://callforme.tel/mcp. Finish the sign-in tab that opens; it asks for no email or card. Grok can then plan calls and look up businesses, and the first real call returns one setup link to add $10. In the xAI API, pass CallForMe as an mcp tool with your key.

Grok can find the right business. With CallForMe connected, it can also call them and tell you what they said.

## Install in Grok (grok.com)

1. Go to **grok.com/connectors**.
2. Click **New Connector**, then choose **Custom**.
3. Paste the server URL: `https://callforme.tel/mcp`
4. Finish the sign-in step. A tab opens and closes by itself: no email, no form, no card. That creates your CallForMe account.

Grok then lists the CallForMe tools (`find_business`, `plan_call`, `place_call`, `get_call` and the rest) in your next chat. Steps are from [xAI's connector docs](https://docs.x.ai/grok/connectors), checked October 30, 2026.

On a Business or Enterprise workspace, ask your admin to provision the connector first.

## If Grok doesn't show a sign-in step

Use a URL that needs no sign-in instead:

- A personal URL, `https://callforme.tel/mcp/k/<your key>`, using a key you create on the [account page](https://callforme.tel/account).
- `https://callforme.tel/mcp/open`, which needs nothing. Grok gets a setup link in each new chat unless it keeps the `account_key` it receives.

## Use it from the xAI API

The xAI Responses API runs remote MCP servers as a tool of type `mcp` ([xAI remote MCP docs](https://docs.x.ai/developers/tools/remote-mcp)):

```python
import os
from openai import OpenAI

client = OpenAI(api_key=os.getenv("XAI_API_KEY"), base_url="https://api.x.ai/v1")

response = client.responses.create(
    model="grok-4.7",
    input=[{"role": "user", "content": "Call Maple Street Pizza at (469) 770-7412 and ask what time they close tonight."}],
    tools=[{
        "type": "mcp",
        "server_url": "https://callforme.tel/mcp",
        "server_label": "callforme",
        "authorization": os.getenv("CALLFORME_KEY"),
        "allowed_tools": ["find_business", "plan_call", "place_call", "get_call", "answer_question"],
    }],
)
print(response.output_text)
```

`CALLFORME_KEY` is a `cfm_...` key from the [account page](https://callforme.tel/account). The API has no approval prompts, so `allowed_tools` is how you keep an app to the tools you want. A call can take a few minutes: `get_call` with `wait_seconds` waits for the result. For a call your code follows step by step, the [REST API](/docs/rest-api) may fit better.

## Your first real call in Grok

The first time Grok places a real call, CallForMe sends back a one-time setup link and Grok shows it to you. Open it, check the call it describes, and add $10. Auto-reload keeps the balance topped up, so you do this once. Details in [how setup links work](/docs/setup-links).

## Try it in Grok

Start with a free demo call. Paste this into Grok:

> Call Maple Street Pizza at (469) 770-7412 and book a table for 2 tonight at 7 under Alex. Ask for the confirmation number, then tell me how it went.

Demo lines are fictional and free. Then swap in a business you use ($1 if answered, nothing if not):

> Find three auto shops near me open Saturday, call each one and ask the price of a front brake pad replacement on a 2018 Honda Civic. Put the answers in a table.

## FAQ

### Which Grok plans can add a custom connector?

xAI's connector docs say connectors are available to all Grok users, as of October 30, 2026. On Business and Enterprise workspaces a team admin has to provision a connector before members can use it.

### Can I use CallForMe from the xAI API?

Yes. The Responses API takes a tool of type mcp with server_url https://callforme.tel/mcp and your CallForMe key as authorization. The API doesn't support approval prompts, so limit allowed_tools if your app shouldn't place calls without a person checking.

### Does Grok call the business itself?

No. Grok decides who to call and what to ask; CallForMe places the call with its own voice assistant, works the phone menu, waits on hold and sends the answers back to Grok.
