Use CallForMe in Meta Muse

Yes, even Muse users can use CallForMe. Muse supports custom MCP connectors: ask Muse in chat to create a custom connector for https://callforme.tel/mcp/open using remote streamable HTTP, or give it a key from your account page. The first real call returns a setup link you open to add $10.

Muse's built-in calling is a limited beta that reaches US businesses only, and some accounts find it turned off at the moment they say go. Since September 18, 2026 Muse can add third-party MCP connectors, so you can give it CallForMe instead. Every CallForMe call is placed by software and says so in the first sentence.

Install

Muse doesn't have an MCP settings page. You set up custom connectors by asking in chat:

Create a custom connector called CallForMe. It's a remote MCP server using streamable HTTP at https://callforme.tel/mcp/open. It doesn't need authentication.

Muse builds the connector, tests it, and saves it. Approve it when Muse asks.

Muse runs in Meta's cloud, which is fine: CallForMe is a public HTTPS server.

Connecting your account

Muse's custom connectors are built around API keys and headers, so there are two good ways to connect:

• No sign-in: use https://callforme.tel/mcp/open as the URL, as in the install prompt above. Muse gets a setup link the first time it calls. Ask Muse to save the account_key it receives, or it will see a setup link again in the next session.
• Your own key: create a key on the account page, then give Muse the header Authorization with the value Bearer cfm_your_key when it asks for credentials. Muse keeps it in its secure credential store. A personal URL, https://callforme.tel/mcp/k/<your key>, also works.

The standard URL, https://callforme.tel/mcp, uses OAuth. Muse can follow it by sending you a sign-in link, but the two options above are simpler.

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.

Why use CallForMe inside Muse

• Works when Muse calling isn't enabled on your account. CallForMe is available to anyone who adds it.
• Calls to Canadian businesses too. CallForMe dials US and Canadian numbers.
• Clear disclosure. Calls open with "Hi, I'm an automated assistant calling on behalf of..." and never claim to be human. There's no human call center behind them.
• You see the price. $1 per answered call including 5 minutes, $0.25 per minute after, nothing if nobody answers.
