- Security & auth, 71 against 62

## 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.

**Saleor API + MCP.** One GraphQL schema with 78 typed error-code enums and 464 marked deprecations. The MCP server can't create checkouts or orders.

## 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

### Saleor API + MCP

1. Pass the channel slug on product and checkout queries. Prices and availability are per channel
2. Send X-Saleor-API-URL and X-Saleor-Auth-Token on every MCP request, with a token holding MANAGE_PRODUCTS and MANAGE_ORDERS
3. Read the `errors` array in every mutation payload. A 200 response can still carry a CheckoutErrorCode
4. Keep queries under the 50,000 complexity cap and 100 items a page, and send at most 4 mutations per request
5. The 3.24 changelog removes the old dummy payment plugins, so test checkouts should use a payment app
