## 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:
- Transparency & trust, 90 against 70

Also in its favour:
- Open source

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

### Square (B)

Good for: Agents working for a seller already on Square, on catalogue, inventory, orders, payment links and customers, online and in person.

Ahead on:
- Schema & documentation, 87 against 82
- Agent ergonomics, 83 against 67
- Security & auth, 67 against 60
- Payments & pricing, 40 against 30
- Maintenance & community, 81 against 75

Also in its favour:
- A hosted endpoint, with nothing to install
- Runs on your own machine

Watch for: The MCP server is marked beta, and the remote server reaches production data only

## 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.

**Square.** The REST API has a public OpenAPI 3.0 spec, OAuth scopes split by read and write for each resource, idempotency keys on writes and a free sandbox. The MCP server is in beta and its remote instance reaches production only. No numeric REST rate limits or SLA were found, and the status page recorded widespread errors on 27 September 2026.

## 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

### Square

1. Test against the sandbox first with the local MCP server and `SANDBOX=true`. The remote server at mcp.squareup.com reaches production only
2. Set `DISALLOW_WRITES=true` on the local MCP server when the task only reads
3. Call `get_service_info`, then `get_type_info`, before each `make_api_request`. The request body is otherwise untyped
4. Send a fresh `idempotency_key` on every write, and reuse it when retrying the same write
5. Pin `Square-Version` in each request. Use a page cursor within 5 minutes of receiving it
