Qweaver WhatsApp MCP

A hosted Model Context Protocol server for a WhatsApp number you pair yourself. Connect once by scanning a QR, then Claude, ChatGPT, Cursor or any MCP client can read your chats, search history and send messages. Unlike servers built on Meta's Business API, it reads your normal WhatsApp conversations; unlike the open-source alternatives, there is nothing to install and no bridge to keep running.

Notes for AI agents

Seven tools: get_session_status, list_chats, search_messages, list_messages, search_contacts, send_message, mark_read. Deliberately small: servers exposing 165-280 tools measurably degrade a model's tool selection. get_session_status reports connection health AND the remaining send budget, so an agent can pace itself instead of discovering a limit by hitting it. send_message reaches a real person from a real number: confirm recipient and wording with your human first. This uses the WhatsApp Web method, not Meta's official Business API, so it can read personal chats but no provider on this method can guarantee a number is never restricted. Use it for your own conversations and replies, never cold outreach or bulk campaigns.
