Use CallForMe in Warp

By Jake Marsh · Updated Nov 2, 2026 · 1 min read

Short answer: In Warp, open Settings, then AI, then MCP Servers, click Add, and paste a JSON entry with url https://callforme.tel/mcp. Log in once when Warp asks, which creates your account. Warp's agent can then call businesses, and shows one setup link the first time it places a call.

Warp's agent supports MCP servers, and it also has a shell, so it can use either the MCP tools or curl with the skill.

Install in Warp

1. Open Settings, then AI, then MCP Servers (or search the command palette for "MCP").
2. Click + Add.
3. Paste:

{
  "mcpServers": {
    "callforme": {
      "url": "https://callforme.tel/mcp"
    }
  }
}

4. Save and start the server.

Signing in from Warp

When the server starts, Warp shows a Login / Authenticate prompt for callforme. Click it. A browser tab opens and closes by itself. There's no email, no form and no card. That creates your CallForMe account.

If Warp doesn't show a sign-in step

If Warp never shows a sign-in step, use one of these instead:

• https://callforme.tel/mcp/open needs no sign-in. Your agent gets a setup link in each new session unless it saves the account_key it receives.
• A personal URL, https://callforme.tel/mcp/k/<your key>, or the header Authorization: Bearer cfm_..., using a key you create on the account page.

To use a header in Warp, edit the entry and add "headers": { "Authorization": "Bearer cfm_your_key" }.

Your first real call in Warp

The first time Warp places a real call, CallForMe sends back a one-time setup link and Warp shows it to you. Open it, check the call it describes, and add $5. Turn on auto-reload (one click right after paying) and the balance tops itself up, so you do this once. Details in how setup links work.

Try it in Warp

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

Call Elm Avenue Garage at (469) 300-6608 and ask what a synthetic oil change costs for a 2018 Honda Civic and the earliest time they can fit me in.

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

Call Riverbend Honda and book a test drive for a CR-V hybrid Saturday afternoon under Chris Doyle.
