## Which one, for what

### commercetools (BB)

Good for: Enterprises that already run or plan a composable commerce stack and want agents working across catalogue, pricing, carts and orders under scoped credentials.

Ahead on:
- Reliability, 73 against 58
- Transparency & trust, 81 against 70

Also in its favour:
- Agent-ready, a grade of BB or better

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

Ahead on:
- Payments & pricing, 40 against 20

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

## Verdicts

**commercetools.** A public OpenAPI file with 822 operations, per-resource OAuth scopes and a managed MCP server whose tools an administrator selects per agent. Prices are quoted by sales only, and the HTTP API publishes no platform-wide rate limit. A 60-day trial needs no card.

**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

### commercetools

1. Use the auth and API hosts for the project's region, such as auth.europe-west1.gcp.commercetools.com and api.europe-west1.gcp.commercetools.com. There are five regions
2. Send the resource's current `version` with every update or delete. On 409 ConcurrentModification, re-read the resource and retry only if the change is still needed
3. Retry 502 and 503 with exponential backoff from 200 ms, honour Retry-After, and check Content-Type before parsing an error body
4. For MCP, ask for an API Client scoped to `mcp:{projectKey}:{mcpServerKey}` and a server limited to the tools the task needs, not `all`
5. Keep page size at or under 500 and offset at or under 10,000. Product Search returns at most 100 per request

### 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
