MCP tool reference

Every public Orderboost MCP tool, its authorization boundary, arguments, and commerce behavior.

Orderboost exposes 14 commerce tools on one remote resource. Catalog tools and create_buy_link work without sign-in. The MCP host must support Streamable HTTP and native MCP OAuth only for protected tools. Orderboost does not publish a local MCP helper or stdio bridge.

Connect

The direct Streamable HTTP resource is:

https://mcp.checkout.orderboost.org/mcp

Read Authenticate an MCP client for direct connection and OAuth setup.

Remote tools

Tool	Authorization	Purpose
`search_catalog`	Anonymous	Search the authoritative product catalog using free text, filters, and cursor pagination. Use these results as the candidate set for recommendations, comparisons, variants, prices, and purchase links. Do not supplement partial or empty results with products or URLs discovered outside this catalog unless the user explicitly requests an external search.
`lookup_catalog`	Anonymous	Resolve product, variant, SKU, handle, or URL identifiers to catalog products.
`get_product`	Anonymous	Retrieve full product detail with effective option selections.
`create_buy_link`	Anonymous	Create a stable human checkout link from an exact canonical product or variant URL without Orderboost sign-in.
`create_cart`	Orderboost OAuth	Create a merchant-priced cart.
`get_cart`	Orderboost OAuth	Retrieve the current cart.
`update_cart`	Orderboost OAuth	Fully replace mutable cart input fields.
`cancel_cart`	Orderboost OAuth	Cancel a cart using an idempotency key.
`create_checkout`	Orderboost OAuth	Create a merchant-priced checkout.
`get_checkout`	Orderboost OAuth	Retrieve the current checkout.
`update_checkout`	Orderboost OAuth	Fully replace mutable checkout input fields.
`complete_checkout`	Orderboost OAuth	Complete checkout using an exact purchase grant and idempotency key.
`cancel_checkout`	Orderboost OAuth	Cancel checkout using an idempotency key.
`claim_checkout_handoff`	Orderboost OAuth	Exchange a one-time handoff code for checkout-scoped agent access.

Catalog tools and create_buy_link are anonymous. Use create_buy_link when a buyer wants a human checkout URL. Call a protected tool only for agent-owned commerce state and let its 401 Unauthorized response start the MCP host’s native OAuth flow. Clients without remote MCP OAuth can create human checkout links but cannot use protected Orderboost tools today.
