Call a Human MCP

I built a small MCP server that lets any AI agent (Claude Desktop, Cursor, Windsurf) block and wait for a human response before taking irreversible actions.

  Two tools:
  - ask_human(question) – agent blocks until you reply
  - request_approval(action) – agent blocks until you click Approve or Deny

  Notifications via Slack (with interactive buttons), or native macOS
  dialogs. Works with any MCP-compatible client over stdio or SSE.

  The use case that motivated it: I kept coming back to find my agent had done
  something I didn't want while I was away. Now it just asks.
