Delete the browser
AI agents call delete-browser to permanently remove resources in TgeBrowser MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool performs an irreversible deletion operation on browser resources. While the blast radius is limited to isolated browser environments managed by this MCP server (not system-wide), deletion of a browser instance and its data cannot be recovered.
