Can I process a refund for a payment ID through the agent?

Yes! Use the `refund_checkout_payment` tool with the payment ID. You can also specify an optional amount in minor units for a partial refund. The agent will trigger the refund process in Checkout.com immediately.

How do I see the full history of actions for a payment?

Use the `list_payment_actions` tool with the unique payment ID. Your agent will fetch all lifecycle events, such as Authorization, Capture, and Refund, along with their timestamps.

Where do I find my API Prefix?

The API Prefix is the first 8 characters of your client_id (excluding the cli_ prefix). You can also find it in your Checkout.com Hub under Developers -> API Keys.

Checkout.com + Claude Desktop FAQ

Common questions about integrating Checkout.com 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.
