Independent open source maintainer lharries, whose implementation is the most widely forked WhatsApp MCP server.

An MCP server that bridges a personal WhatsApp account via a local WhatsApp Web connection so an AI assistant can search, read, and send messages, including media.

Runs locally on the user's machine, linked to their WhatsApp account through a QR code scan similar to WhatsApp Web.

First published in 2024 and widely forked and extended through 2025.

Lets an agent triage, summarize, or reply to a person's real WhatsApp conversations on their behalf.

Requires an MCP client, a local Go or Python bridge process, and linking a real WhatsApp account via QR code; no official API key exists since it is unofficial.

Community maintained, unofficial and not affiliated with WhatsApp or Meta, typically MIT licensed, can send messages on the linked account so it can modify chat state, runs entirely locally with message history cached on disk.
