send_secret
Prompt the human operator for a secret via GUI dialog; sends it to the PTY session without exposing it to AI context or logs ¹
How to use it
send_secret is exposed by the Pty MCP MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), and the send_secret tool becomes available to the model automatically. See the full listing for setup details and every tool this server provides.
