## 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.

**Saleor API + MCP.** One GraphQL schema with 78 typed error-code enums and 464 marked deprecations. The MCP server can't create checkouts or orders.

## 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

### Saleor API + MCP

1. Pass the channel slug on product and checkout queries. Prices and availability are per channel
2. Send X-Saleor-API-URL and X-Saleor-Auth-Token on every MCP request, with a token holding MANAGE_PRODUCTS and MANAGE_ORDERS
3. Read the `errors` array in every mutation payload. A 200 response can still carry a CheckoutErrorCode
4. Keep queries under the 50,000 complexity cap and 100 items a page, and send at most 4 mutations per request
5. The 3.24 changelog removes the old dummy payment plugins, so test checkouts should use a payment app
