Tool changes

2026-10-05uxc_discover_toolsadded
Search tools across every u.cash MCP server by name or description (case-insensitive substring), optionally scoped to one server. Returns the tool, a one-liner, its server, and how to connect. Discovery only - connect to that server directly; no call is ever proxied.
2026-10-05uxc_discover_serversadded
List every u.cash MCP server in the fleet (buyer, seller, prime, legacy): product surface, auth model, transports with install coordinates, docs URL. Optional q filters by name/product/summary. Discovery only - connect to each server directly with your own credentials; no call is ever proxied.

Tools (14)

`uxc_cancel_checkout`	Cancel a UCP checkout session. No key; pass cloud for a hosted merchant.
`uxc_complete_checkout`	Mint payment challenges for a checkout session -> ready_for_complete. Optional ap2 (AP2 checkout mandate). No key; pass cloud for a hosted merchant.
`uxc_create_checkout`	Create a UCP checkout session (multi-item, mixed-currency cart) for a merchant catalog. No key. Returns {id, status, currency, line_items, totals, ap2}.
`uxc_discover_servers`	List every u.cash MCP server in the fleet (buyer, seller, prime, legacy): product surface, auth model, transports with install coordinates, docs URL. Optional q filters by name/product/summary. Discovery only - connect to each server directly with your own credentials; no call is ever proxied.
`uxc_discover_tools`	Search tools across every u.cash MCP server by name or description (case-insensitive substring), optionally scoped to one server. Returns the tool, a one-liner, its server, and how to connect. Discovery only - connect to that server directly; no call is ever proxied.
`uxc_get_checkout`	Fetch a UCP checkout session by id (status: incomplete -> ready_for_complete -> completed). No key; pass cloud for a hosted merchant.
`uxc_get_market`	The PUBLIC cross-merchant market catalog: every published checkout across merchants (id, title, price, currency, merchant, domain, payable url). No key. q filters by title/merchant/description.
`uxc_get_order`	View a UCP checkout session as an order (per-item fulfillment status + fulfillment events). No key; pass cloud for a hosted merchant.
`uxc_get_product`	Fetch a single catalog product by id. Public (no key); pair with uxc_search_catalog to find ids.
`uxc_get_services`	The PUBLIC cross-provider services catalog (eSend rail: each row carries the provider contact email, a sendable asset code and a price). No key.
`uxc_lookup_products`	Batch catalog lookup by ids. Public (no key).
`uxc_search_catalog`	Search a merchant catalog (text query + price filters + pagination). The merchant is resolved from a cloud token (the "cloud" argument) or the platform default. No key.
`uxc_verify_payment`	BUYER-SIDE. After paying a resource (from uxc_view_door) on-chain from your own wallet, submit the transaction hash to settle it. Pass the challengeId from the accepts[] entry you paid and the on-chain transaction hash. Returns settled (confirmed) or pending (awaiting confirmations). No seller key needed - the challengeId identifies the resource, and settlement is gated by on-chain confirmation.
`uxc_view_door`	Fetch the public 402 payment door for a resource (what a buyer sees at https://agents.u.cash/r/{res_id}): the price + the multi-coin accepts[] (each asset, the seller receive address, and the exact amount to pay). No key. Use as a BUYER to see what to pay, then uxc_verify_payment after paying. status=true polls settlement without minting a new challenge.
