WHAT IT DOES

What rhino.validate_model does on CoWork OS

AI agents call rhino.validate_model to retrieve information from CoWork OS without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why rhino.validate_model is rated Low

Validation tools typically read and analyze existing data to check for errors or constraint violations, producing a report without altering any state. The word 'validate' strongly implies a read-only inspection operation. No side effects are indicated in the description.

From the tool's definition 'Validate layer, geometry, and architectural constraints' — validation implies checking/querying existing model data without modification

RECOMMENDED RULE

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

rhino.validate_model Allowed

rhino.validate_model is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "rhino.validate_model": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect CoWork OS, apply this rule, and every rhino.validate_model call is checked against it from then on.
