Verdicts

Adobe Commerce (Magento)

Public Swagger files cover 510 REST operations for the cloud service, the GraphQL schema carries cart, checkout and order mutations, and the cloud service authenticates by OAuth 2 through Adobe IMS. No request rate limit or idempotency key was found in the API documentation, Adobe publishes no MCP server for Commerce, and a licence starts with a sales order.

BigCommerce API + MCP

Published rate limits per plan, with X-Rate-Limit-Time-Reset-Ms on every 429. Storefront MCP is beta, switched on per store, has no back-office tools and documents no tool annotations.

Before you call either

Adobe Commerce (Magento)

  1. Ask which deployment the store is. The cloud service answers at https://<server>.api.commerce.adobe.com/<tenant-id>/ with no /rest prefix, and other stores at https://<host>/rest/<store-view-code>/
  2. On the cloud service, request an IMS token with the commerce.accs scope and send the Store header to pick the store view
  3. On a 2.4 store, sign requests with all four integration credentials by OAuth 1.0a. A bare integration token is refused unless the merchant has switched that on
  4. Add ?fields= to REST calls and set searchCriteria[pageSize]. Stores with input limits on cap a page at 300 items
  5. Don't retry placeOrder or a POST blindly. Read the cart or order back first, because no idempotency key was found

BigCommerce API + MCP

  1. Give the agent a store-level API account with only the scopes the task needs, and delete it when done
  2. On a 429, wait X-Rate-Limit-Time-Reset-Ms before retrying
  3. Expect up to 10 minutes after a store owner enables the MCP before the URL answers
  4. The MCP stops at a checkout URL. Payment happens in the shopper's browser
  5. Point a coding agent at the docs MCP at https://docs.bigcommerce.com/_mcp/server
