Use CallForMe in LM Studio

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

Short answer: Open LM Studio, go to the Program tab, choose Install, then Edit mcp.json, and add a callforme entry with url https://callforme.tel/mcp. Click Login once; no email or card. Your local model can then plan calls and look up businesses. The first real call shows one setup link.

Your model runs locally; the phone call runs on CallForMe. Pick a model that handles tool calls well.

Install in LM Studio

One click

https://lmstudio.ai/install-mcp?name=callforme&config=eyJ1cmwiOiJodHRwczovL2NhbGxmb3JtZS50ZWwvbWNwIn0=

Or edit mcp.json

In the right sidebar open Program, then Install, then Edit mcp.json (the file lives at ~/.lmstudio/mcp.json):

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

LM Studio loads it when you save.

Signing in from LM Studio

After you save, LM Studio shows a Login 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 LM Studio doesn't show a Connect step

If your version of LM Studio can't do OAuth sign-in, 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_... in the entry's headers, using a key you create on the account page.

Picking a model

The call loop needs a model that calls tools reliably and can wait and poll. Larger instruction-tuned models with tool-use support do best. If a small model stops polling early, ask it to "keep calling get_call until status is ended".

Your first real call in LM Studio

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

Start with a free demo call. Paste this into LM Studio:

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 Corner Bistro and ask how long the walk-in wait is right now for 2 people.
