Use CallForMe in Meta Muse

By Jake Marsh · Updated Nov 4, 2026 · 3 min read

Short answer: Maybe. As of October 2026 we haven't confirmed that Muse can add an MCP server: Meta describes custom connections built around API credentials, not MCP. If your Muse offers custom connectors, ask it to create one for https://callforme.tel/mcp/open (remote streamable HTTP). If that doesn't work, use CallForMe from Claude or ChatGPT.

Muse's built-in calling is a beta for calls to US businesses (Muse itself is available in the US, Canada and, since October 27, 2026, Singapore). We haven't confirmed that Muse can add MCP servers (as of October 2026, Meta's help pages describe custom connections built around API credentials). If yours can, here is how to try CallForMe in it. Every CallForMe call is placed by software and says so whenever asked.

Try it in Meta Muse

Muse doesn't have an MCP settings page. If it supports custom connectors for you, you set them up 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.

If Muse can build the connector, it tests and saves it; approve it when it asks. If it says it can't, use CallForMe from Claude or ChatGPT instead.

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

Signing in from Meta Muse

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.

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, this is an assistant calling for (your name), on a recorded line." and never claim to be human. There's no human call center behind them.
• You see the price. $1 per answered call including the first 2 minutes, $0.40 per minute after, nothing if nobody answers.

Your first real call in Meta Muse

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

Start with a free demo call. Paste this into Meta Muse:

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):

Use CallForMe to call Nonna's Kitchen and book a table for 4 Friday between 7 and 8:30. Ask for a booth. Reservation under Sam.
