Rael UCP Commerce MCP Server
Rael's storefront exposes a live, anonymous MCP server implementing the Universal Commerce Protocol (UCP) shopping service. An unauthenticated POST of {"jsonrpc":"2.0","id":1, "method":"tools/list"} returned HTTP 200 with 13 tools, each carrying a complete JSON Schema inputSchema — no OAuth challenge, no API key. The saved manifest in rael-mcp-tools.json is the verbatim response body.
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.
