## 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.

Also in its favour:
- A hosted endpoint, with nothing to install
- No incidents deducted, where Shopware loses 5 points for them

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

### Shopware (BB)

Good for: A merchant already on Shopware, or a team that wants an MIT PHP backend with a built-in MCP server for back-office work.

Ahead on:
- Reliability, 83 against 70
- Schema & documentation, 85 against 79
- Agent ergonomics, 78 against 64
- Security & auth, 73 against 64
- Payments & pricing, 50 against 25
- Maintenance & community, 87 against 82
- Transparency & trust, 76 against 57

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

Watch for: The MCP server is marked experimental until 6.8, and 6.7.14.0 changed what tools/list returns on the Store API endpoint

## 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.

**Shopware.** MIT-licensed core with OpenAPI specs for both APIs and a built-in MCP server that advertises three discovery tools, previews writes by default and limits each integration to an allowlist. The MCP server is experimental until 6.8, and 20 security advisories were published between May and September 2026, four of them critical.

## 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

### Shopware

1. Ask the merchant for an integration without --admin, tied to an ACL role and an MCP allowlist. Send sw-access-key and sw-secret-access-key headers to /api/_mcp
2. Call shopware-tool-search first, then shopware-toolset-enable, and keep the Mcp-Session-Id header. A fresh session lists only three tools
3. Pass dryRun=false to commit a write. shopware-media-upload has no dry run and uploads at once
4. For shopping, call the Store API over HTTP with the sales channel's sw-access-key and keep the sw-context-token. The Store API MCP endpoint has no cart tools in core
5. Send `includes` in search criteria to cut response size, and read the 429 body for the wait time
