## 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
