WhatsApp Connect MCP Server
A WhatsApp MCP server shipped as a single static Go binary. One download, one setup command, one QR scan - then any MCP client (Claude Desktop, Claude Code, Cursor, Windsurf, Cline, …) can read, search, and send WhatsApp messages, with every outbound send protected by a server-enforced gate.
People who need communication tools inside Claude, Cursor, VS Code, or another MCP client. The project is written in Go.

03 · What WhatsApp Connect can do
Prose above is summarized from the project's README and registry record - no invented capabilities.
Limitations (from the README)
- Your number can be banned, and this project cannot prevent it. See Ban risk. This is the limitation that matters most. - History depth is phone-decided. Like every WhatsApp Web client, the paired phone controls how much chat history syncs to this server. There is no setting here that fetches more than the phone hands over. setup --full-history asks for as much as the protocol allows instead of the default few month
