WHAT IT DOES

What review.model_tier does on Visionmcp

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

RISK

Why review.model_tier is rated Medium

The tool records (writes) a tier decision, which is a durable state change in the system. It does not delete data or execute arbitrary code. The constraint 'acceptance cannot exceed a valid receipt's fidelity' implies validation logic around the write, not a destructive or financial operation.

From the tool's definition 'Record a tier decision' — the tool writes/commits a tier classification decision for a model

RECOMMENDED RULE

The rule that runs review.model_tier safely

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

review.model_tier Rate-limited

review.model_tier 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.
