amused-ucp-shopping
AMUSED Co exposes an agent-native commerce surface via the Universal Commerce Protocol (UCP, https://ucp.dev), served over MCP by the underlying Shopify platform. The store's /.well-known/ucp profile advertises a UCP "dev.ucp.shopping" service over MCP transport, plus an embedded transport. Checkout requires contemporaneous human buyer approval; the endpoint is rate-limited per IP (back off on HTTP 429). Tool schemas are the UCP OpenRPC documents referenced in the profile.
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.
Browse every MCP server on the APIs.io network or compare with the broader Agent Skill surfaces of the same providers.
Work with this as data
Every MCP server here is available over the APIs.io API and to AI agents over MCP.
