## Which one, for what

### Adobe Commerce (Magento) (B)

Good for: An agent working for a merchant already on Adobe Commerce or Magento, for catalogue, order and B2B back-office work over REST and for carts and checkout over GraphQL.

Ahead on:
- Security & auth, 60 against 40
- Transparency & trust, 90 against 71

Watch for: No request rate limit for the REST or GraphQL APIs was found in the reviewed documentation, and 429 handling appears only in a code sample

### Medusa API + MCP (B)

Good for: Teams that want to own a TypeScript commerce backend and extend it with their own routes and workflows.

Ahead on:
- Agent ergonomics, 72 against 67
- Payments & pricing, 50 against 30
- Maintenance & community, 93 against 75

Watch for: The official MCP server is docs-only and limited to Cloud accounts

## Verdicts

**Adobe Commerce (Magento).** Public Swagger files cover 510 REST operations for the cloud service, the GraphQL schema carries cart, checkout and order mutations, and the cloud service authenticates by OAuth 2 through Adobe IMS. No request rate limit or idempotency key was found in the API documentation, Adobe publishes no MCP server for Commerce, and a licence starts with a sales order.

**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.

## Before you call either

### Adobe Commerce (Magento)

1. Ask which deployment the store is. The cloud service answers at `https://<server>.api.commerce.adobe.com/<tenant-id>/` with no `/rest` prefix, and other stores at `https://<host>/rest/<store-view-code>/`
2. On the cloud service, request an IMS token with the `commerce.accs` scope and send the `Store` header to pick the store view
3. On a 2.4 store, sign requests with all four integration credentials by OAuth 1.0a. A bare integration token is refused unless the merchant has switched that on
4. Add `?fields=` to REST calls and set `searchCriteria[pageSize]`. Stores with input limits on cap a page at 300 items
5. Don't retry `placeOrder` or a POST blindly. Read the cart or order back first, because no idempotency key was found

### 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
