WhatsApp via LMCP

LMCP links WhatsApp to the user's computer as a linked device (macOS and Windows). Messages are kept in a local store on the computer, so search works across all chats.

Core tools

• Setup: whatsapp_connect shows the QR code in the chat; whatsapp_diagnose checks the link; whatsapp_list_accounts when there is more than one number.
• Read: whatsapp_list_chats, whatsapp_read_messages, whatsapp_search_messages, whatsapp_search_contacts, whatsapp_read_poll.
• Groups: whatsapp_list_groups, whatsapp_group_info, whatsapp_create_group.
• Send: whatsapp_send_message, whatsapp_send_file, whatsapp_send_poll.
• whatsapp_sync pulls the latest messages, groups and contacts into the local store.

Good practice

• Resolve the person with whatsapp_search_contacts before reading or sending.
• Summarize conversations rather than pasting every message.
• Every send is preview-first: show the chat and the text, confirm, then send.
• If a tool says WhatsApp isn't linked, offer whatsapp_connect instead of retrying.
