Clean WhatsApp contact verification in Claude Desktop

Stop guessing if a phone number is active. This MCP Server lets you run `check_number` directly inside Claude Desktop to filter out invalid contacts before you queue up a broadcast. Your desktop client handles the API check behind the scenes. You avoid delivery failures and keep your WhatsApp sender score healthy without leaving the chat window.

Automate group setup from Claude Desktop chats

Spinning up team chats or customer threads is tedious. Ask your chat agent to run `create_group` with a list of phone numbers, and Claude Desktop configures the group instantly. You can also call `list_groups` to find existing threads. Your agent will map the returned group UUIDs to your project files so you can target the right audience.

Send text and media files using this MCP Server

Drop a public image URL into your desktop chat and tell the agent to send it. Claude Desktop uses `send_message` along with `list_numbers` to select your active sender line and push the media out. It handles both direct messages and group updates. You get immediate delivery confirmation right in your conversational history.
