Verdicts

Medusa API + MCP

MIT core you can self-host, with Medusa Cloud running the same APIs and no GMV fee. The official MCP server is docs-only and limited to Cloud accounts.

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

Medusa API + MCP

  1. Send x-publishable-api-key on every /store call. It decides which sales channels and products the agent sees
  2. Ask for only the fields you need with fields. Store routes reject relations nested more than three deep since 2.20.0
  3. Read the store's regions before creating a cart, since prices and shipping options depend on region
  4. Place the order with POST /store/carts/{id}/complete after shipping and payment sessions are set
  5. Read the release notes before upgrading a minor version. Breaking changes land there

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
