Connects to MarketCheck automotive data to search active and sold car listings in US, Canada, and UK markets. Muse can help you find vehicles by specs and location, predict fair prices with comparable listings, decode VIN details, and track a car's online listing history.

Example request: "Find used Honda Civics under $20,000 within 50 miles of my zip code and show me what similar cars are selling for."

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