## 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.

**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

### 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

### 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
