WHAT IT DOES

What measurement.add does on Visionmcp

AI agents use measurement.add 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 measurement.add is rated Medium

The tool creates/writes a new measurement record with associated metadata. It has no indication of irreversibility or destructive action, and doesn't execute code or move money. It is a data write operation (recording/creating a measurement entry).

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs measurement.add 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 measurement.add, this is the rule to start with:

measurement.add Rate-limited

measurement.add 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.
