html_restore · Llama MCP: Risk & Policy

WHAT IT DOES

What html_restore does on Llama

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

WHY IT NEEDS A POLICY

Why html_restore needs a policy

The tool performs a copy/restore operation that creates new data based on old versions. This is a Write operation (creates/modifies data reversibly) rather than Destructive because the action is reversible—the new version can be edited or deleted.

From the tool's definition Tool name 'html_restore' and description 'Restore an old HTML version by copying it forward as a new' indicates the tool creates a new copy of a previous HTML version, which is a reversible modification operation.
