Uninstalls a Chrome extension by its ID.
AI agents call uninstall_extension to permanently remove resources in Opera DevTools MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Uninstalling an extension is a destructive action that cannot be automatically reversed. An AI agent misusing this tool could remove security extensions, productivity tools, or user-critical functionality without consent or recovery mechanism. This belongs in the Destructive category (not Execute) because the action itself is the destructive outcome, not a tool that executes arbitrary code.
From the tool's definition Tool name is 'uninstall_extension' and description states it 'Uninstalls a Chrome extension by its ID.' The verb 'uninstalls' indicates an irreversible removal action.
