Frequently asked questions
How do I find my Holded API Key?
Log in to your Holded account, click on the Settings icon (top right), go to Developers, and you will find your unique API Key listed there. You can create multiple keys for different integrations.
What document types are supported in the invoicing tools?
This integration currently focuses on the invoice document type. For other types like sales orders or purchase orders, you can use the generic list_invoices logic if they are mapped under the same module in your instance.
Can I update stock levels through this integration?
Yes! Use the update_product_stock tool. You must provide the product ID and a JSON string containing the warehouse ID and the new quantity to update your inventory.
Is the integration secure for ERP data?
Absolutely. The integration uses official Holded API keys in the request header over HTTPS. Your credentials and business data are encrypted and stored securely within the Vinkius Cloud infrastructure.
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.
Server not appearing after restart
Ensure the JSON is valid (no trailing commas). Check the file path: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\\Claude\\ (Windows).
Authentication error
Verify your Vinkius token is correct. Go to cloud.vinkius.com to regenerate it if needed.
Tools not showing in chat
Click the 🔌 icon at the bottom of the chat input. If it shows 0 tools, the server may still be connecting. wait a few seconds.
