FAQ

Frequently asked questions

How do I find my Handwrytten API Key?

Log in to your Handwrytten dashboard, go to Settings, and then to the API Keys section. You can generate a new key or copy your existing one from there.

Can I use realistic handwriting fonts?

Yes! Handwrytten uses robots with real pens. You can list all available styles using the list_fonts tool and specify the font_id when sending a card.

How do I check if my card was sent?

Use the list_orders tool to see your history of sent cards or get_order with a specific order ID to check its current fulfillment status.

Is it possible to include gifts with the cards?

Yes, Handwrytten offers various gifts. You can list available items using the list_gifts tool and include the gift ID in your order request.

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.
