cancel
Destroys a room this session created (files + metadata deleted), or leaves a joined room.
How to use it
cancel is exposed by the Justdrop MCP MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), and the cancel tool becomes available to the model automatically. See the full listing for setup details and every tool this server provides.
