Integration with Cursor/Claude Desktop

Copy the below json with the appropriate {{PATH}} values:

{
  "mcpServers": {
    "whatsapp": {
      "command": "{{PATH_TO_UV}}", // Run `which uv` and place the output here
      "args": [
        "--directory",
        "{{PATH_TO_SRC}}/whatsapp-mcp/whatsapp-mcp-server", // cd into the repo, run `pwd` and enter the output here + "/whatsapp-mcp-server"
        "run",
        "main.py"
      ]
    }
  }
}
