flying-embers-ucp-shopping
Flying Embers serves a live, unauthenticated Model Context Protocol endpoint on its own domain as part of the Universal Commerce Protocol (UCP) shopping service. A tools/list call returns 13 real tools with full JSON Schema input contracts covering catalog search and lookup, cart lifecycle, checkout lifecycle, and order retrieval. The surface is provided by the Shopify commerce platform but is served from www.flyingembers.com, advertised by the merchant's own /llms.txt, /agents.md and /robots.txt, and the UCP merchant profile names this merchant explicitly (merchant_name "Flying Embers", merchant_origin www.flyingembers.com).
One-click install for Cursor, VS Code, Claude, and 20+ other MCP clients, powered by API Commons MCP Install — visit install.apicommons.org for more information.

About MCP
The Model Context Protocol (MCP) is an open protocol Anthropic introduced for connecting LLM-based agents to external tools and data sources. Providers publish MCP servers that expose their API surface as structured, discoverable tools — an MCP-compatible client (Claude Desktop, Cursor, Cline, Continue, etc.) can connect to the server and call its tools without any per-provider integration code.

Work with this as data
Every MCP server here is available over the APIs.io API and to AI agents over MCP.
