## 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 55
- Schema & documentation, 86 against 81
- Agent ergonomics, 83 against 72
- Security & auth, 70 against 40
- Transparency & trust, 81 against 71

Also in its favour:
- Agent-ready, a grade of BB or better
- A hosted endpoint, with nothing to install
- Runs on your own machine

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

### 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:
- Payments & pricing, 50 against 20
- Maintenance & community, 93 against 85

Also in its favour:
- Open source

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

## 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.

**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

### 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

### 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
