## Verdicts

**Elastic Path API + MCP.** Cart, promotion code, checkout and order endpoints cover the whole test flow. MCP server exposes 95 tools with full CRUD, no read-only mode and no public source or licence.

**Shopify API + MCP.** Typed GraphQL schemas with quarterly versions supported at least 12 months. Closed platform. You can't self-host or change checkout internals.

## Before you call either

### Elastic Path API + MCP

1. Use a client_credentials token server-side only. It has full CRUD on the store
2. Pick the base URL for the store's region (useast or euwest), or every call returns 401
3. Loading the MCP server costs 95 tool definitions, so enable it only for agents that need the back office
4. On a 429, wait a few seconds and retry. No Retry-After header is sent
5. Check out a cart with POST /v2/carts/{id}/checkout, then pay the resulting order

### Shopify API + MCP

1. Pin an API version in the URL and plan to move at least once a year. Old versions fall forward to the oldest supported one
2. Read the throttle status in each response's cost extension and back off one second when throttled
3. Send an agent profile in `meta` on every UCP call, and an idempotency key on every checkout write
4. Check `userErrors` on every mutation. A 200 response can still carry a failed write
5. Add @shopify/dev-mcp while writing code so the agent checks queries against the current schema
