Verdicts

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.

commercetools

A public OpenAPI file with 822 operations, per-resource OAuth scopes and a managed MCP server whose tools an administrator selects per agent. Prices are quoted by sales only, and the HTTP API publishes no platform-wide rate limit. A 60-day trial needs no card.

Before you call either

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

commercetools

  1. Use the auth and API hosts for the project's region, such as auth.europe-west1.gcp.commercetools.com and api.europe-west1.gcp.commercetools.com. There are five regions
  2. Send the resource's current version with every update or delete. On 409 ConcurrentModification, re-read the resource and retry only if the change is still needed
  3. Retry 502 and 503 with exponential backoff from 200 ms, honour Retry-After, and check Content-Type before parsing an error body
  4. For MCP, ask for an API Client scoped to mcp:{projectKey}:{mcpServerKey} and a server limited to the tools the task needs, not all
  5. Keep page size at or under 500 and offset at or under 10,000. Product Search returns at most 100 per request
