Use CallForMe in Warp

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

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.

Connecting your account

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.

Your first call

The only other step comes once, the first time your agent places a real call. CallForMe answers with a short setup link like https://callforme.tel/go/k7m2q, and your agent shows it to you.

1. Open the link. It shows the exact call about to be placed: who, what number, and the goal.
2. Add $10. Your card is saved and auto-reloads, so you won't see this page again. Creators can claim credit with their email instead.
3. The page says you're done. Tell your agent to continue, and the phone starts ringing.

After that, every chat and every session just calls. If you later add CallForMe to a second agent, its first call link recognizes you (when you're signed in on that browser) and links it to your account in one click, with no second payment. More in how setup links work.

Want to test it first? Ask your agent to call Maple Street Pizza, a fictional restaurant, at (469) 770-7412. Demo calls are free, with no payment, up to 5 a day.

If the sign-in step doesn't appear

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" }.

Try it

Paste this into Warp:

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