Let Claude or Cursor read your WhatsApp Web folders (locally, over MCP)

#whatsapp #mcp #ai #productivity

I wanted to ask Claude "what's still open with my clients?" and get an answer from WhatsApp, where those conversations live. So WA Folders 1.3 added an MCP connection: your AI agent can read the WhatsApp Web folders you allow, and nothing else.

What you need

  • Chrome with WhatsApp Web open
  • WA Folders from the Chrome Web Store
  • Node.js 18 or newer
  • An MCP app: Claude Desktop, Cursor, Codex, or any other

Steps

  1. Download the agent bridge from https://wafolders.com/ai-agent/, unzip it and run install-windows.ps1 (Windows) or bash install-mac-linux.sh (Mac).
  2. Add the MCP server the installer prints to your agent app. In Claude Desktop it looks like {"mcpServers":{"wa-folders":{"command":"node","args":["<path>/wa-folders-agent.js"]}}}.
  3. Open the WA Folders options page, find AI agent access (off by default), tick Allow AI agent access and tick the folders the agent can see.
  4. Ask something: "Summarize my chat with Ana" or "What's waiting on a reply in Clients?"

What the agent can and can't do

  • It can search and summarize chats in allowed folders.
  • If you tick the extra box, it can move chats between your ticked folders and set reminders.
  • It never sends a WhatsApp message.
  • Everything runs on your computer. There is no WA Folders server and nothing goes to the cloud from the extension.
  • Revoke all agent access with one click in the same panel.

Price

Free to try. Pro is $4.99 once, no subscription.
