Connects to Simsima's eSIM marketplace. Muse can search plans by destination and data needs, recommend plans for your trip length, check coverage, and generate checkout links for purchase.

Example request: "Find me the cheapest eSIM plan with 5GB of data for my trip to Japan next week"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Simsima Connectivity to help me. It is a free service with an MCP server at https://mcp.simsima.io/mcp. It does not need an API key. 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.
