Frequently asked questions
What sender IDs can I use to send SMS messages?
You must use a registered AT&T shortcode or dedicated long code as the sender ID. Unregistered or random numbers will be rejected by the carrier. You can provision new shortcodes with keywords using the create_shortcode tool, or check your existing ones through the messaging dashboard. Each shortcode can be configured with multiple keyword auto-responses.
Can I send MMS with images and what formats are supported?
Yes. The send_mms tool accepts a publicly accessible media URL. Supported formats include JPEG, PNG, GIF for images, MP4 for video, and common audio formats. The media URL must be reachable by AT&T's servers -- local or private URLs will fail. Maximum file size limits apply per carrier specifications, typically up to 1MB for images and 3.5MB for video.
How do I handle customer opt-out requests like STOP?
AT&T Messaging automatically processes standard opt-out keywords (STOP, CANCEL, UNSUBSCRIBE, QUIT). When a customer sends one of these, they are added to your suppression list and will no longer receive messages from that shortcode. You can monitor inbound messages with get_inbound_messages to track opt-out activity and verify your keyword configuration with get_keyword_responses.
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.
