What vision.reconstruct does on Visionmcp
AI agents use vision.reconstruct 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 vision.reconstruct is rated Medium
The tool creates/materializes a new editable candidate object, which is a Write operation (creates data). It explicitly does NOT promote to accepted authority, so it is reversible and non-destructive. The candidate is editable, implying it can be modified or discarded. Medium severity because misuse could create spurious candidates or pollute the workspace, but no irreversible damage occurs.

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

vision.reconstruct is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the vision.reconstruct rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
