Can I send a WhatsApp message to a customer who hasn't messaged me first?

Yes, but you must use an approved template message. The `send_template_message` tool allows you to initiate communication using these templates. If the user has messaged you in the last 24 hours, you can use `send_session_message` for free-text replies.

How do I see what templates are available to send?

Use the `list_whatsapp_templates` tool. It will return all your approved and pending message templates, allowing you to choose the right one for your communication needs.

Can I check the delivery status of my broadcast campaigns via chat?

Yes. The `list_broadcast_campaigns` tool provides a list of your previous and active WhatsApp broadcasts, including their delivery statistics, so you can track performance directly from your agent.

Wati + Claude Desktop FAQ

Common questions about integrating Wati MCP Server with Claude Desktop.

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.
