## Which one, for what

### Commerce Layer API + MCP (B)

Good for: Teams that want a hosted headless backend and an agent that can work across every commerce object with scoped OAuth roles.

Ahead on:
- Payments & pricing, 25 against 20

Watch for: No price between the free plan and a sales-quoted Enterprise contract

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:
- Schema & documentation, 86 against 79
- Agent ergonomics, 83 against 64
- Security & auth, 70 against 64
- Transparency & trust, 81 against 57

Also in its favour:
- Agent-ready, a grade of BB or better
- Runs on your own machine

Watch for: No public price. The pricing page describes order-based pricing and sends buyers to sales

## Verdicts

**Commerce Layer API + MCP.** Public OpenAPI 3.0 file and llms.txt. No price between the free plan and a sales-quoted Enterprise contract.

**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.

## Before you call either

### Commerce Layer API + MCP

1. Call `get_resource_schema` before any write. Preflight rejects bad filter shapes before they reach the API
2. Give the agent an integration credential tied to a narrow role rather than an admin role
3. On a 429, wait out the sliding window. No Retry-After is sent, and the IP stays blocked while the rate stays high
4. Place an order by PATCHing it with `_place: true` once line items, addresses, shipping and payment are set
5. Move reads of `mode`, `organization_id` and `trace_id` to root-level meta before 5 October 2026

### 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
