Verdicts

Fabric

Public OpenAPI files for about 980 operations, llms.txt, client credentials with role-limited system apps, and a published 99.9 per cent SLA. Access needs a sales contract, with no public price or self-serve trial. The commerce docs are labelled legacy, the newest release notes date from July 2025, and no status page was found.

Shopify API + MCP

Typed GraphQL schemas with quarterly versions supported at least 12 months. Closed platform. You can't self-host or change checkout internals.

Before you call either

Fabric

  1. Get the tenant ID and a System App client ID and secret from the merchant's Copilot admin, with the narrowest role the task needs
  2. Request a new system token from {authURL}/v1/token every 10 minutes, since system apps receive no refresh token
  3. Send x-fabric-tenant-id on every call, and x-fabric-channel-id where the merchant sells in more than one channel
  4. Page order searches with offset and limit, because the default response returns 10 orders
  5. Read errorCode and context.endpoint in Orders and Inventory errors, and check for duplicates before retrying a write

Shopify API + MCP

  1. Pin an API version in the URL and plan to move at least once a year. Old versions fall forward to the oldest supported one
  2. Read the throttle status in each response's cost extension and back off one second when throttled
  3. Send an agent profile in meta on every UCP call, and an idempotency key on every checkout write
  4. Check userErrors on every mutation. A 200 response can still carry a failed write
  5. Add @shopify/dev-mcp while writing code so the agent checks queries against the current schema
