ucp-agentic-commerce

Universal Commerce Protocol (UCP) expert for building agentic commerce implementations. Use PROACTIVELY when the user is implementing UCP checkout flows, merchant servers, platform integrations, payment handlers, order management, discovery profiles, or any agentic commerce feature using UCP across REST, MCP, A2A, or Embedded bindings.

Implement UCP AP2 Mandates extension — cryptographic payment mandates for fully autonomous agent commerce using SD-JWT credentials, merchant authorization signatures, and the Agent Payments Protocol. Use when building autonomous agent payment flows without human-in-the-loop.

Implement the UCP Buyer Consent extension — GDPR/CCPA consent collection, consent fields in checkout sessions, and privacy-compliant consent management. Use when adding consent flows, privacy compliance, or data processing agreements to UCP checkout.

Implement UCP Checkout over the A2A (Agent-to-Agent) binding — enable autonomous agent-to-agent commerce using Agent Cards and structured message parts. Use when building agent-to-agent commerce flows.

Implement UCP Checkout over the MCP (Model Context Protocol) binding — expose checkout operations as MCP tools for AI agents. Use when building an MCP server that AI agents like Claude or Gemini can call for commerce, or when integrating with Shopify's MCP endpoint.

Implement UCP Checkout over the REST binding — create, get, update, complete, and cancel checkout sessions with proper headers, idempotency, status transitions, and error handling. Use when building REST-based UCP checkout endpoints or clients.
