## Before you call it

1. Use the agent for back-office jobs (orders, refunds, discounts, stock, abandoned carts), not for placing orders
2. Start with a test-mode key (ST_ prefix) before switching to live (SL_)
3. Send the key in X-Snipcart-Api-Key. OAuth-only clients can't connect
4. Stay under 100 MCP requests a minute and 10 in flight per key
5. Ignore unknown response fields. Snipcart adds fields without a new version

## Connect

```bash
curl -H "Accept: application/json" https://app.snipcart.com/api/orders -u "$SNIPCART_SECRET_KEY:"
```

```bash
claude mcp add --transport http snipcart https://ai.snipcart.com/mcp --header "X-Snipcart-Api-Key: $SNIPCART_SECRET_KEY"
```
