Use CallForMe in Zed

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

Short answer: Add a callforme entry under context_servers in Zed's settings.json with url https://callforme.tel/mcp, then click Authenticate once to create your account. Zed's agent panel can then call businesses, and it shows one setup link the first time it places a real call.

Zed calls MCP servers context servers. Remote ones take a URL.

Install in Zed

Open settings with zed: open settings (cmd-,) and add:

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

Open the agent panel settings, click Authenticate next to callforme, and confirm it shows as active. You can also add it from the agent panel with Add Custom Server.

Signing in from Zed

Because the entry has no Authorization header, Zed shows an Authenticate button for callforme in the agent panel settings. 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 Zed doesn't show a sign-in step

If Zed 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 Zed:

{
  "context_servers": {
    "callforme": {
      "url": "https://callforme.tel/mcp",
      "headers": { "Authorization": "Bearer cfm_your_key" }
    }
  }
}

Your first real call in Zed

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

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

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):

Call Harbor Hotel and ask if early check-in at noon on Saturday is possible and what overnight parking costs.
