Shopping gateway that lets Muse users search for physical products across participating merchants, check inventory and pricing, build carts, and proceed to merchant-hosted checkout. Handles product discovery, comparison, and purchase handoff.

Example request: "Find and buy a wireless headset under $100 with fast shipping."

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

Tools:
- search_products: Primary shopping entry point. Use when a user wants to find, browse, compare, recommend, price-check, check availability of, shop for, or buy a physical product. Searches purchasable products across merchants participating in the Agent Checkout network. The user does not need to 
- search_catalog: Legacy alias for search_products. Search purchasable products across participating merchants. Prefer search_products for new shopping requests.
- get_product: Get detailed product and variant information after search_products identifies a product and merchant. Use before purchase when the user needs details, options, price, or variant information.
- check_inventory: Check whether a selected product variant is currently sellable and available. Use when availability matters or immediately before adding a selected variant to a cart.
- create_cart: Create a new Agent Checkout-attributed cart with a selected product variant. Use only after the user has chosen a specific product or clearly asked to add/buy it. This prepares the purchase but does not charge the buyer.
- add_to_cart: Add another selected product variant to an existing Agent Checkout cart. Use when the user explicitly wants another item or quantity added to an existing cart. This does not charge the buyer.
- get_cart: Read the current Agent Checkout cart contents and totals. Use to review or confirm the cart before handing the buyer off to checkout.
- create_checkout: Prepare the final buyer handoff by returning the merchant-hosted HTTPS checkout URL. Use when the user has a cart and clearly wants to proceed to checkout or purchase. Always surface checkoutUrl to the human buyer. Agent Checkout never collects raw card details and this tool does
