Brooklinen UCP / MCP Agentic Commerce API

Live Universal Commerce Protocol (UCP) endpoint exposed over MCP JSON-RPC at https://www.brooklinen.com/api/ucp/mcp, advertised by the store's own /agents.md, /robots.txt and /.well-known/ucp discovery profile. Provides agent-driven catalog search and lookup, cart management, checkout creation/update/completion and order retrieval against the Brooklinen storefront. Requires a resolvable UCP agent profile (meta.ucp-agent.profile / UCP-Agent header) — anonymous tools/list returns JSON-RPC error -32001 invalid_profile_url. Payment completion requires explicit human buyer approval.
