export_pack · Godot MCP Unified MCP: Risk & Policy

WHAT IT DOES

What export_pack does on Godot MCP Unified

AI agents use export_pack to create or update resources in Godot MCP Unified — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot MCP Unified environment.

WHY IT NEEDS A POLICY

Why export_pack needs a policy

The tool writes/creates exported game packages (PCK or ZIP files) as a side effect, but does not permanently delete, modify existing project data irreversibly, or execute arbitrary code. The export operation is reversible (exported files can be deleted). While it produces output artifacts, it falls short of Destructive (no data loss) or Execute (no code execution triggered by untrusted input).

From the tool's definition Tool description states 'Export a Godot project as PCK or ZIP file' — this creates new files on the filesystem.
