Rock The Bells Commerce MCP Server (UCP)
Rock The Bells serves a live, anonymously-listable Model Context Protocol server on its own storefront host at https://shop.rockthebells.com/api/ucp/mcp. It implements the Universal Commerce Protocol (UCP) shopping service, exposing 13 tools that let an agent search the Rock The Bells catalog, build a cart, and drive a checkout to completion. The endpoint is advertised by the store's own /llms.txt, /agents.md and /robots.txt.
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.
