Verdicts

Shopify API + MCP

Typed GraphQL schemas with quarterly versions supported at least 12 months. Closed platform. You can't self-host or change checkout internals.

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

Shopify API + MCP

  1. Pin an API version in the URL and plan to move at least once a year. Old versions fall forward to the oldest supported one
  2. Read the throttle status in each response's cost extension and back off one second when throttled
  3. Send an agent profile in meta on every UCP call, and an idempotency key on every checkout write
  4. Check userErrors on every mutation. A 200 response can still carry a failed write
  5. Add @shopify/dev-mcp while writing code so the agent checks queries against the current schema

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
