Frequently asked questions
How do I format phone numbers for sending SMS?
Phone numbers must include the country code without the 00 prefix. For example: China uses 86 (e.g., 8615800000000), Brazil uses 55 (e.g., 5511999999999), US uses 1 (e.g., 12025551234). The number should be 5-20 digits total. For Chinese domestic SMS, the message must start with a registered signature like [YourBrand].
What's the difference between send_sms and send_international_sms tools?
The send_sms tool uses the standard SMS gateway (smssh.253.com) optimized for Chinese domestic messages and requires pre-registered templates and signatures. The send_international_sms tool uses the international gateway (intapi.253.com) for global delivery outside China, which supports SenderId and doesn't require Chinese-style signatures. International SMS permissions must be separately enabled in your account.
How does the MD5 signature authentication work?
The Chuanglan API uses MD5 signature authentication for security. Your password is NEVER sent in the request body. Instead, it's combined with the request parameters and timestamp (nonce), then hashed with MD5 to generate a sign header. The server validates this signature to ensure request integrity. The framework handles all signature generation automatically — you only need to provide your account and password.
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.
