CarMD Universal Commerce (UCP) MCP Server
CarMD serves a live, anonymous Model Context Protocol endpoint on its own domain at https://carmd.com/api/ucp/mcp. It is the Shopify-provided Universal Commerce Protocol (UCP) commerce server for the CarMD store — it sells CarMD Connect hardware, not the CarMD Vehicle API. It was probed directly: `initialize` returned serverInfo {"name":"universal-commerce","version":"0.1.0"} with protocolVersion 2024-11-05, and `tools/list` returned 13 tools with full JSON Schema 2020-12 inputSchemas, saved verbatim to mcp/carmd-ucp-tools-list.json. No CarMD Vehicle API MCP server exists; the developer API host api.carmd.com refused connections at probe time.
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.
