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.

Vendure

Full cart, coupon, shipping and payment flow in the GraphQL Shop API, with ErrorResult types an agent can branch on. No vendor-hosted API. Vendure Cloud is only partly available.

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

Vendure

  1. Keep the session token from the first Shop API response and send it on every call. It holds the active order
  2. Check each mutation result's __typename and errorCode. Expected failures return 200 with an ErrorResult
  3. Don't retry addItemToOrder blindly. Read the active order first, since a repeat adds the quantity again
  4. For server-side work, enable api-key in authOptions.tokenMethod and give the key one role in one channel
  5. Run 3.7.3 or later, and purge old job records, which may still hold session tokens
