Frequently asked questions
Can my AI send SMS and track delivery status?
Yes. Use send_sms to deliver a text message, then get_sms_status with the returned message ID to check delivery confirmation in real time.
How does phone verification work through the AI?
Two steps: first, send_verification sends an OTP code to the user's phone. Then, check_verification validates the code the user submits. Both operations run through the 8x8 Verify API.
Can I send messages through WhatsApp and other chat channels?
Yes. The send_chat_message tool supports WhatsApp, Viber, and LINE. Just specify the channel, recipient identifier, and message text.
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.
