How do I get my VTEX API credentials?

Log in to your VTEX Admin, go to **Account Settings → Application Keys**, and create a new App Key. You'll receive an App Key and App Token pair. You also need your Account Name (the subdomain you use to access the VTEX Admin, e.g., 'mystore'). No code, no SDK — just connect and go.

Can my agent simulate a full cart with shipping costs?

Yes! Use the 'simulate_order' tool with a list of items and a postal code. Your agent will return the full cart breakdown — totals, per-item pricing, available logistics options, estimated delivery dates, and applicable discounts — all without touching the actual store.

What happens when a customer asks support about their current cart?

Your support agent can use the 'get_orderform' tool to instantly retrieve the customer's active cart — items, quantities, prices, applied coupons, and shipping address. No need to switch tabs or navigate the admin. The agent can then apply a coupon or check shipping costs, all within the same conversation.

Can I validate payment conditions before placing bulk orders?

Absolutely. The 'simulate_payment' tool lets your agent validate payment tokens and check accepted conditions — perfect for operations teams running bulk order validations across multiple sellers and payment methods without processing real transactions.

VTEX Checkout + Claude Desktop FAQ

Common questions about integrating VTEX Checkout MCP Server with Claude Desktop.

How does Claude Desktop discover MCP tools?

When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.

What happens if the MCP server is temporarily unavailable?

Claude Desktop handles disconnections gracefully — if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.

Can I connect multiple MCP servers simultaneously?

Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.

Is there a limit on the number of tools per server?

Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.

Does Claude Desktop support Streamable HTTP transport?

Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL — Claude auto-negotiates the transport protocol.
