What visual_geometry.create_rig does on Visionmcp
AI agents use visual_geometry.create_rig 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 visual_geometry.create_rig is rated Medium
The tool 'creates' a rig (visual geometry configuration), which is a Write operation — it establishes/freezes a new review rig structure. The description mentions 'freeze' and 'receipt-bound' suggesting it commits/saves a configuration state. Unapproved cameras remain diagnostic implies this is reversible and non-destructive.

Attacks that exploit this kind of access
The rule that runs visual_geometry.create_rig 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 visual_geometry.create_rig, this is the rule to start with:
visual_geometry.create_rig 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 visual_geometry.create_rig call is checked against it from then on.
