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.
