go_forward · Selenium MCP: Risk & Policy

WHAT IT DOES

What go_forward does on SeleniumMCP

AI agents invoke go_forward to trigger actions in SeleniumMCP. 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, which constitutes an external operation that changes the browser state. Navigating forward can cause page loads, form submissions, or other side effects depending on the browser history context, making it an Execute-level action rather than a simple Read.

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.
