Frequently asked questions
How can my AI generate ZATCA-compliant invoices?
Simply use the create_invoice tool. Your agent can instantly generate six types of invoices (including B2C and B2B), all fully compliant with ZATCA Phase 2, complete with QR codes, UUIDs, and cryptographic stamps.
Is it possible to programmatically access my client list and VAT numbers?
Yes. By executing the list_customers action, your AI agent can retrieve your entire client registry, including tax identification numbers, addresses, and contact details for seamless CRM integration.
Can I automatically issue credit notes for partial returns?
Absolutely. Ask the agent to use the create_credit_note tool. It will safely generate a ZATCA-compliant credit note linked to the original invoice, adjusting the accounting records automatically.
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
