What reference.import_reviewed_mask does on Visionmcp
AI agents use reference.import_reviewed_mask 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.
Why reference.import_reviewed_mask is rated Medium
This tool creates a binding/association between a mask and an image reference, which is a write/create operation. It modifies metadata or annotations by attaching a reviewed mask to an image reference. The operation appears reversible (it's a binding, not a deletion), and while the image reference itself is described as 'immutable', the act of binding a mask to it is a write action.

Attacks that exploit this kind of access
The rule that runs reference.import_reviewed_mask 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 reference.import_reviewed_mask, this is the rule to start with:
reference.import_reviewed_mask 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Visionmcp, apply this rule, and every reference.import_reviewed_mask call is checked against it from then on.
