WHAT IT DOES

What page_forward does on Jshookmcp

AI agents invoke page_forward to trigger actions in Jshookmcp. 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 page_forward is rated High

Triggers browser navigation action, changing state of an external browser session.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs page_forward safely

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

page_forward Rate-limited

page_forward 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 Jshookmcp, apply this rule, and every page_forward call is checked against it from then on.
