WHAT IT DOES

What save_file_version does on Webcake Storefront

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

RISK

Why save_file_version is rated Medium

This tool performs a Create operation (saves/writes a new version snapshot) rather than destructive action, as versions can be managed and old versions are not irreversibly deleted by this operation. The severity is medium because misuse could fill storage with unnecessary snapshots or interfere with legitimate rollback workflows, but the core operation is reversible.

From the tool's definition Tool description states 'Save a version snapshot of a CMS file for rollback' — this creates a new version record in the CMS system, modifying (adding to) the versioning history.

save_file_version Rate-limited

save_file_version stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
