Connect to Capmus, a classifieds marketplace for university communities. Search listings by category and price, message posters, and create draft posts to sell items or offer services. Includes verified poster badges for campus community members.

Example request: "Find a used textbook for sale on my university's Capmus marketplace."

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