Choose the right integration path

Connect Claude

1. In your Xevryn account, go to AI agent keys and create a key with the scopes you need (for example: cart:write, checkout:handoff, order:read). The full key is shown only once when you create it.
2. In Claude → Settings → Connectors, add a custom connector pointing to the MCP URL above and paste the bearer token.
3. Start a chat and try: 'Find me a minimalist black top under S/180.' Claude will call search_products / get_product / recommend_size / check_inventory automatically.

Authentication model

Discovery surfaces can stay public, but any cart mutation or checkout handoff should use scoped bearer agent keys minted by a Xevryn admin or a shopper through personal agent keys when enabled.

Payment handoff

Agents never process payments in chat. The start_checkout_handoff tool mints a single-use signed URL (/checkout/handoff?token=…) that migrates the agent cart into the browser session and drops the user on Xevryn's existing Mercado Pago checkout.
