Anthropic Claude tools receive integration guide and Windows CLI fix

Anthropic released a setup guide for the PushEngage MCP server, enabling users to run push‑notification workflows directly within Claude Desktop, Claude Code or Cursor. The guide details installation steps, required environment variables, login procedures and common connection issues, allowing businesses to manage campaigns, A/B tests and analytics without leaving their coding environment.

A separate technical note addresses a Windows‑specific problem where the Claude Code CLI fails to launch Claude Desktop, displaying a "Claude Desktop is not installed" error despite the app being present. The fix involves creating a version‑specific folder in the local app data directory to satisfy the CLI’s version check, after confirming the registry key for MSIX installations. This resolves the launch issue and also provides a deep‑link method for opening saved sessions in Claude Desktop.
