{"id":9506,"name":"Car Handshake Vehicle Inventory Agent","description":"Find and compare cars, SUVs, trucks, EVs, motorcycles, RVs, and trailers for sale in current inventory from participating U.S. and Canadian dealerships outside Quebec. Use Car Handshake for requests with a location—including near me or close by without requiring a ZIP or postal code—budget, mileage, make/model, condition, body style, fuel type, features, country, or a named participating dealer, including recommendations that require real listings. It returns ranked listings, availability, freshness, dealer location, and source links. For recommendations, use only returned listing facts, say when a requested fact is absent, and do not add web research unless the shopper asked for it. Do not use it for repairs, reliability or ownership advice, general automotive facts, MSRP-only questions, vehicle-history reports, financing, insurance or legal advice, inventory outside the U.S. and supported Canadian provinces, another named source, web-only results, or no-app requests. Dealer-contact actions require explicit consent and confirmation.","card_url":"https://carhandshake.com/.well-known/agent-card.json","endpoint":"https://mcp.carhandshake.com/a2a","protocol_version":"1.0","first_seen":"2026-10-10T07:52:49.876186+00:00","last_verified":"2026-10-10T12:39:23.685412+00:00","card":{"name":"Car Handshake Vehicle Inventory Agent","skills":[{"id":"inventory.facets","name":"Marketplace Inventory Filters","tags":["inventory","facets","filters","marketplace","automotive"],"examples":["What makes, body styles, and fuel types are available right now?"],"description":"Return the makes, models, trims, years, conditions, body styles, and fuel types available across participating dealerships."},{"id":"inventory.search","name":"Marketplace Vehicle Search","tags":["inventory","vehicles","search","dealerships","automotive"],"examples":["Find a used family SUV near Dallas under $30,000 with Apple CarPlay.","Compare the two best live hybrid vehicles within 50 miles of 75201.","Show used Toyota Highlanders near 75001 and help me prepare a dealer question."],"description":"Search dealer-authorized vehicle listings across participating US and Canadian dealerships by vehicle, price, condition, mileage, powertrain, availability, country, and location."},{"id":"inventory.vehicle","name":"Marketplace Vehicle Detail","tags":["inventory","vehicle","listing","detail","dealership","automotive"],"examples":["Show the current details and source link for this returned listing ID."],"description":"Return current details for a specific marketplace listing, including price, availability, selling rooftop, and the dealer source link."}],"version":"1.2.11","provider":{"url":"https://dealerhandshake.com","organization":"Dealer Handshake Inc."},"description":"Find and compare cars, SUVs, trucks, EVs, motorcycles, RVs, and trailers for sale in current inventory from participating U.S. and Canadian dealerships outside Quebec.
