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.

Shopware

MIT-licensed core with OpenAPI specs for both APIs and a built-in MCP server that advertises three discovery tools, previews writes by default and limits each integration to an allowlist. The MCP server is experimental until 6.8, and 20 security advisories were published between May and September 2026, four of them critical.

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

Shopware

  1. Ask the merchant for an integration without --admin, tied to an ACL role and an MCP allowlist. Send sw-access-key and sw-secret-access-key headers to /api/_mcp
  2. Call shopware-tool-search first, then shopware-toolset-enable, and keep the Mcp-Session-Id header. A fresh session lists only three tools
  3. Pass dryRun=false to commit a write. shopware-media-upload has no dry run and uploads at once
  4. For shopping, call the Store API over HTTP with the sales channel's sw-access-key and keep the sw-context-token. The Store API MCP endpoint has no cart tools in core
  5. Send includes in search criteria to cut response size, and read the 429 body for the wait time
