Athletic Brewing UCP Commerce MCP Server

Athletic Brewing's Shopify storefront serves a live, anonymous Model Context Protocol endpoint implementing the Universal Commerce Protocol (UCP) dev.ucp.shopping service. Discovered from the store's own /llms.txt, /agents.md and /robots.txt, confirmed against /.well-known/ucp, and introspected directly: an unauthenticated tools/list returned all thirteen tools with complete JSON Schema. This is not a developer program Athletic Brewing built — it is the Shopify commerce platform's agent surface, served from Athletic Brewing's own host and advertised in Athletic Brewing's own robots.txt.

Connect

This is a remote MCP server — point an MCP client at the endpoint URL. Clients with native remote support (Claude, Cursor, VS Code, …):

# mcp client config (e.g. .mcp.json / mcp settings) { "mcpServers": { "athletic-brewing": { "url": "https://athleticbrewing.com/api/ucp/mcp" } } }

For stdio-only clients (older Claude Desktop, etc.), bridge with mcp-remote:

# Add to claude_desktop_config.json { "mcpServers": { "athletic-brewing": { "command": "npx", "args": ["-y", "mcp-remote", "https://athleticbrewing.com/api/ucp/mcp"] } } }

If the server requires authentication, add the provider's token/header (e.g. an X-API-Key) per its docs. A quick reachability check:

curl -i -X POST https://athleticbrewing.com/api/ucp/mcp \ -H "Content-Type: application/json" -H "Accept: application/json, text/event-stream" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

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.
