WHAT IT DOES

What statistics_calc does on UnClick

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

Parameter	Type	Required	Description
`numbers`	string	Yes	Comma-separated numbers or array.

Parameters from the server's own tool schema.

RISK

Why statistics_calc is rated Medium

An AI agent can call statistics_calc faster than any human can review: one bad instruction and it creates or modifies resources in UnClick by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs statistics_calc safely

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

statistics_calc Rate-limited

statistics_calc 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 UnClick, apply this rule, and every statistics_calc call is checked against it from then on.
