description: >-
  Off Grid Stores publishes no OpenAPI, so this profile is built from the OAuth/OIDC discovery
  documents its own host serves and from live authenticated-vs-anonymous probes of each surface. The
  authorization server is Shopify's customer-account issuer bound to this shop, with all user-facing
  endpoints on account.offgridstores.com.
surfaces:
- surface: Storefront GraphQL API
  endpoint: https://offgridstores.com/api/2025-10/graphql.json
  scheme: none
  type: public
  probed: '2026-08-26'
  note: >-
    Answered a full introspection query (422 types) and a shop/paymentSettings query with no
    Authorization header and no X-Shopify-Storefront-Access-Token. Customer-scoped fields still
    require a customer access token minted by customerAccessTokenCreate.
- surface: Storefront MCP server
  endpoint: https://offgridstores.com/api/mcp
  scheme: none
  type: public
  probed: '2026-08-26'
  note: tools/list and tools/call both succeeded anonymously.
- surface: UCP Commerce MCP server
  endpoint: https://offgridstores.com/api/ucp/mcp
  scheme: none
  type: agent-profile
  probed: '2026-08-26'
  note: >-
    tools/list is anonymous. tools/call returns HTTP 422 with JSON-RPC error -32001 "UCP discovery
    failed" / invalid_profile_url until a resolvable agent profile URI is supplied in
    meta.ucp-agent.profile, which every tool's inputSchema marks required. The agent profile is an
    identity document, not a bearer credential; Shopify's agent-authentication docs cover the JWT
    that accompanies it.
- surface: Storefront JSON endpoints
  endpoint: https://offgridstores.com/products.json
  scheme: none
  type: public
  probed: '2026-08-26'

  endpoint: https://account.offgridstores.com/authentication/oauth/authorize
