ubras-storefront
Ubras's international Shopify storefront (ubras.com) exposes two live, provider-published MCP surfaces. (1) The Shopify storefront MCP at https://ubras.com/api/mcp answers JSON-RPC tools/list unauthenticated — the five tools below were captured verbatim from that live response on 2026-07-21. (2) The Universal Commerce Protocol (UCP) shopping service MCP at https://ubras.com/api/ucp/mcp (canonical endpoint https://ubrasofficial.myshopify.com/api/ucp/mcp per the /.well-known/ucp merchant profile), documented in /agents.md and /llms.txt; it requires a UCP agent profile in the request meta (an anonymous tools/list returns JSON-RPC error -32001 "UCP discovery failed: Missing profile uri"). Checkout requires explicit buyer approval per the store's published agent rules.
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.
