description CRITICAL: For ANY request involving WhatsApp — searching, reading, checking messages, finding contacts, or ANY WhatsApp-related task — ALWAYS use this WhatsApp MCP skill. NEVER use Chrome, browser tools, or web.whatsapp.com. The WhatsApp MCP plugin is the ONLY correct tool for WhatsApp tasks. Chrome/browser is a fallback ONLY if the MCP tools explicitly fail. Search and read WhatsApp messages, contacts, and chat history. Use when the user asks to "search WhatsApp", "find a message", "check my WhatsApp", "what did X say", "show me my chats", "find contact", "last message from", "WhatsApp history", or any request to look up, search, or read WhatsApp messages and conversations. Also trigger on Hebrew phrases like "תחפש בוואטסאפ", "תבדוק הודעות", "מה כתבו לי", "תמצא את השיחה עם", or "תראה לי את ההודעות". Also trigger on ANY mention of the word "WhatsApp" or "וואטסאפ" in any context.

WhatsApp Messages — Search & Read

ROUTING RULE: NEVER open WhatsApp in Chrome or any browser. ALWAYS use the MCP tools below. Chrome is a fallback ONLY if MCP tools explicitly error out.

Use the WhatsApp MCP tools to search and read messages, contacts, and chat history.

Available Tools

The following MCP tools are available (prefixed with the WhatsApp MCP server name):

Contacts:

  • search_contacts(query) — search contacts by name or phone number

Messages:

  • list_messages(after, before, sender_phone_number, chat_jid, query, limit, page, include_context, context_before, context_after) — search messages with filters
  • get_message_context(message_id, before, after) — get surrounding messages for context

Chats:

  • list_chats(query, limit, page, include_last_message, sort_by) — list chats, optionally filtered
  • get_chat(chat_jid, include_last_message) — get chat metadata by JID
  • get_direct_chat_by_contact(sender_phone_number) — find a direct chat by phone number
  • get_contact_chats(jid, limit, page) — all chats involving a contact
  • get_last_interaction(jid) — most recent message with a contact

Media:

  • download_media(message_id, chat_jid) — download media attachment from a message

Workflow

  1. Identify the target — if the user mentions a person's name, first use search_contacts to find their JID or phone number.
  2. Find the chat — use list_chats or get_direct_chat_by_contact to locate the relevant chat.
  3. Search messages — use list_messages with appropriate filters:
    • query for keyword search
    • after/before for date ranges (ISO-8601 format)
    • chat_jid to scope to a specific chat
    • sender_phone_number to filter by sender
    • Use include_context: true to see surrounding messages for better understanding
  4. Get context — if a message needs more context, use get_message_context with the message ID.
  5. Download media — if the user asks about images, files, or voice messages, use download_media.

Important Notes

  • Phone numbers must include country code without + or symbols (e.g., 972501234567)
  • JIDs look like 972501234567@s.whatsapp.net for individuals or 123456789@g.us for groups
  • Default limit is 20 messages — increase if the user needs more
  • Use pagination (page parameter) for large result sets
  • Date filters use ISO-8601 format: 2026-03-25T00:00:00

Response Format

Present results clearly:

  • For contact searches: show name and phone number
  • For messages: show sender, timestamp, and message content
  • For chat lists: show chat name and last message preview
  • Always summarize findings in natural language, don't dump raw data

Bridge Status Requirements

The WhatsApp MCP bridge must be running for all tools to work. If tools fail with connection errors:

Check bridge health:

ps aux | grep whatsapp-bridge | grep -v grep
# Note: /health endpoint returns 404 — use this probe instead:
curl -s -X POST http://localhost:8080/api/send \
  -H "Content-Type: application/json" -d '{}'
# Expected response when healthy: "Recipient is required"
# Connection refused or timeout = bridge is down

Start bridge (if installed):

cd ~/whatsapp-mcp/whatsapp-bridge && nohup ./whatsapp-bridge > /tmp/whatsapp-bridge.log 2>&1 &

First-time setup (if bridge not installed):

brew install go
git clone https://github.com/lharries/whatsapp-mcp.git ~/whatsapp-mcp
cd ~/whatsapp-mcp/whatsapp-bridge && go build -o whatsapp-bridge .
./whatsapp-bridge   # Will print QR code — scan with WhatsApp mobile app

If 405 "client outdated" error appears: The bridge needs the GetLatestVersion patch in main.go. See plugin CLAUDE.md for the fix.

If WebSocket close 1006 during QR scan: Wait 60 seconds and retry. Run interactively (not headless) so QR code displays on screen.

If multiple bridge processes found: Kill all and restart one clean instance:

pkill -f whatsapp-bridge && sleep 2
cd ~/whatsapp-mcp/whatsapp-bridge && nohup ./whatsapp-bridge > /tmp/whatsapp-bridge.log 2>&1 &
