WHAT IT DOES

What save_document_as does on Aos

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

RISK

Why save_document_as is rated Medium

The tool creates or modifies files by saving a document to a specified path. While it doesn't delete existing data, it can overwrite files at the target path if they exist, making it a Write operation rather than Read. Severity is medium because misuse could result in unintended file creation/overwrites, but this is reversible (the original file persists unless explicitly overwritten).

From the tool's definition Tool name 'save_document_as' and description explicitly indicates it saves/writes the current Rhino document to a new file path. This is a file write operation.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs save_document_as safely

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

save_document_as Rate-limited

save_document_as 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.
