Connects Muse to a service that places real phone calls in Japanese or English. Muse can ask it to call a business, then read back the outcome and a transcript of the conversation.

Example request: "Call the dentist and ask if they have any openings on Friday afternoon."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Callout to help me. It is a free service with an MCP server at https://mcp.callout.jp/mcp. It needs an API key from Callout; ask me to enter it through your secure credential prompt. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.
