Connects to the Trailberg online store for men's, women's and boys' activewear, tracksuits, jackets, footwear and accessories. Muse can search products, show details and size guides, suggest matching pieces, and add, update or remove items in a cart before handing off to checkout.

Example request: "Find a men's tracksuit in medium under $100 and add it to my cart."

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