WHAT IT DOES

What rhino.place_pool does on CoWork OS

AI agents use rhino.place_pool 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.place_pool is rated Medium

The tool creates or modifies pool geometry objects (place = create, revise = update), which are reversible design artifacts. This is a Write operation rather than Read (which would be query-only) or Execute (which would run code/scripts).

From the tool's definition Tool description states 'Place or revise pool geometry' — indicates creation and modification of geometric objects in a design/modeling context.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs rhino.place_pool 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.place_pool, this is the rule to start with:

rhino.place_pool Rate-limited

rhino.place_pool 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.
