## 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.

**Snipcart API + MCP.** Hosted MCP server with 38 documented tools and a self-hostable Bun build. No server-side cart or checkout. Orders only come from the browser widget.

## 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

### Snipcart API + MCP

1. Use the agent for back-office jobs (orders, refunds, discounts, stock, abandoned carts), not for placing orders
2. Start with a test-mode key (ST_ prefix) before switching to live (SL_)
3. Send the key in X-Snipcart-Api-Key. OAuth-only clients can't connect
4. Stay under 100 MCP requests a minute and 10 in flight per key
5. Ignore unknown response fields. Snipcart adds fields without a new version
