How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use ALT eSIM to help me. It is a free service with an MCP server at https://altesim.com/api/mcp.

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.
