go_forward · InSite MCP: Risk & Policy

WHAT IT DOES

What go_forward does on InSite

AI agents invoke go_forward to trigger actions in InSite. 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.

WHY IT NEEDS A POLICY

Why go_forward needs a policy

This tool triggers a browser navigation action (moving forward in history), which is an external browser operation. It doesn't read data passively, write/create data, or destroy anything, but it does execute a browser action that changes the browser's state. Severity is low as the blast radius of navigating forward in history is minimal.

Verdict

go_forward Rate-limited

go_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.
