video_studio_publish_prepare · LocalAnt MCP: Risk & Policy

WHAT IT DOES

What video_studio_publish_prepare does on LocalAnt

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

WHY IT NEEDS A POLICY

Why video_studio_publish_prepare needs a policy

The tool writes metadata files locally, which is a reversible modification operation (Write category). Severity is medium because: (1) it operates on metadata rather than code or sensitive data, (2) an AI agent could be manipulated into writing malformed or misleading platform metadata that affects video publishing workflows, (3) effects are reversible (files can be edited/deleted).

From the tool's definition Tool description explicitly states 'Write platform metadata JSON files' — this creates or modifies data (JSON files) in a reversible manner without executing external actions or deleting data.
