WHAT IT DOES

What eval_page does on 0click Insta

AI agents invoke eval_page to trigger actions in 0click Insta. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why eval_page is rated High

eval_page triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs eval_page safely

PolicyLayer is an MCP gateway: it sits between your AI agents and 0click Insta, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For eval_page, this is the rule to start with:

eval_page Rate-limited

eval_page stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect 0click Insta, apply this rule, and every eval_page call is checked against it from then on.
