WHAT IT DOES

What rhino.save_project does on CoWork OS

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

RISK

Why rhino.save_project is rated Medium

The save operation modifies the project file state reversibly (the file can be reopened, edited, or reverted), making it a Write action rather than Destructive. The severity is medium because improper use could overwrite project work, but the operation is reversible through version control or backup restoration. Confidence is high given the explicit 'save' terminology and clear intent.

From the tool's definition Tool name and description: 'Save the active Rhino project' — this persists/modifies project state on disk.

RECOMMENDED RULE

The rule that runs rhino.save_project safely

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

rhino.save_project Rate-limited

rhino.save_project 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.
