WHAT IT DOES

What update_onedrive_file does on Hermoso

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

RISK

Why update_onedrive_file is rated Medium

This tool modifies file properties (name and folder location) in OneDrive but does not create new content, execute code, delete data, or handle financial transactions. These are reversible Write operations with moderate blast radius if misused by an agent (could rename/relocate files belonging to the user or their organization, causing confusion or disruption, but changes are undoable).

From the tool's definition Tool description states it can 'rename' and 'move' OneDrive items, which are reversible modifications to file metadata and location.

RECOMMENDED RULE

The rule that runs update_onedrive_file safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Hermoso, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For update_onedrive_file, this is the rule to start with:

update_onedrive_file Rate-limited

update_onedrive_file 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.
