Use CallForMe in Claude Code

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

Short answer: Run claude mcp add --transport http --scope user callforme https://callforme.tel/mcp in your terminal. Then run /mcp, pick callforme and choose Authenticate. A tab opens and closes by itself. Your first real call shows one setup link.

Claude Code is the fastest place to try CallForMe. One command adds the MCP server, and the server tells Claude how to plan a call, place it, answer the business's questions mid-call, and read back the result.

Wondering what Claude can and can't do on a call first? See can Claude make phone calls?

Install in Claude Code

One command

From your terminal:

claude mcp add --transport http callforme https://callforme.tel/mcp

Add --scope user to make it available in every project instead of just the current one. Check it with claude mcp list, or run /mcp inside a session, where you'll also authenticate (below).

Or commit it to a project

Commit a .mcp.json at your repo root so everyone on the project gets it:

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

Signing in from Claude Code

After adding the server, run /mcp inside Claude Code, pick callforme, and choose Authenticate. A browser tab opens and closes by itself. There's no email, no form and no card. That creates your CallForMe account, and Claude Code remembers it for every session in that scope.

If Authenticate doesn't show up

Use a key instead. Create one on the account page, then add the server with a header:

claude mcp remove callforme
claude mcp add --transport http callforme https://callforme.tel/mcp \
  --header "Authorization: Bearer cfm_your_key"

Or use the URL https://callforme.tel/mcp/k/<your key>. Details in the MCP reference.

Your first real call in Claude Code

The first time Claude Code places a real call, CallForMe sends back a one-time setup link and Claude Code 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.

The only other step comes once, the first time Claude places a real call. CallForMe answers with a short setup link like https://callforme.tel/go/QF6S-2U4Z, and Claude 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 $5. Your card is saved and auto-reloads, so you won't see this page again. Unused credit never expires. Creators can claim credit with their email instead.
3. The page says you're done. Most agents notice by themselves and the phone starts ringing. If Claude is waiting on you, say "done".

After that, 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.

Try it in Claude Code

Start with a free demo call. Paste this into Claude Code:

Get front brake quotes from the three CallForMe demo auto shops: Oak Street Auto (469) 402-2653, Cedar Lane Tire & Brake (469) 437-9838 and Elm Avenue Garage (469) 300-6608. Call all three at once and give me a table. If they ask about my car, ask me.

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

Find the 3 closest tire shops to 75024 that are open now. Call each one and ask the price to mount and balance 4 tires I bring in, and the earliest slot today. Give me a table.
