They are Shopify platform servers bound to this merchant's shop (shop_id 55184621620, offgridstores.myshopify.com) and served under offgridstores.com, so the endpoints, the catalog they expose and the carts/checkouts they create are Off Grid Stores'. Tool lists below were captured verbatim from live `tools/list` calls on 2026-08-26 and saved alongside this file with their full JSON Schema inputSchemas. deployment: mode: remote endpoint: https://offgridstores.com/api/ucp/mcp auth: none verified: probed checked: '2026-08-26' note: >- `tools/list` answers anonymously on both servers. Invocation differs: /api/mcp executes tools/call anonymously (search_catalog for "solar generator" returned real Off Grid Stores products during the probe), while /api/ucp/mcp returns HTTP 422 with JSON-RPC error -32001 "UCP discovery failed / invalid_profile_url — Unable to fetch agent profile: Missing profile uri", so its write path requires a resolvable UCP agent profile (and, per the tool schemas, a Shopify agent identity). No stdio package is published for either server; `auth: none` records what the anonymous discovery path actually needs. servers: - name: universal-commerce server_version: 0.1.0 endpoint: https://offgridstores.com/api/ucp/mcp alternate_endpoint: https://offgridstores.myshopify.com/api/ucp/mcp alternate_endpoint_note: >- The /.well-known/ucp discovery document names the myshopify.com endpoint; /llms.txt names the offgridstores.com one.
