Verdicts

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.

Wix Stores and eCommerce API

The developer docs are served as Markdown with an llms.txt index, and API keys carry permission scopes and a site restriction. No numeric REST rate limit or OpenAPI file was found, and status.wix.com records a platform-wide incident of 3 hours 17 minutes on 1 August 2026. A person must create the account and the key.

Before you call either

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

Wix Stores and eCommerce API

  1. Send the API key in Authorization with wix-site-id for site calls or wix-account-id for account calls, never both
  2. Fetch the product first and pass product.revision on every Catalogue V3 update, or the call fails with 409
  3. Use Cart V2 for new work. The older eCommerce Cart and Checkout APIs were deprecated on 5 August 2026
  4. Request cursorPaging.limit of at most 100 on Query Products and use Search Products for lookups by name
  5. Over MCP, read the method page with ReadFullDocsArticle before CallWixSiteAPI. Responses are cut at 50,000 characters by default
