navigate_forward · Selenium MCP: Risk & Policy

WHAT IT DOES

What navigate_forward does on Selenium

AI agents invoke navigate_forward to trigger actions in Selenium. 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 navigate_forward needs a policy

While navigation itself is not inherently destructive, it executes a browser command whose consequences depend on the state of browser history and the content of pages being navigated to. Combined with sibling tools like click, execute_js, and alert, this is part of a browser automation suite capable of triggering side effects.

From the tool's definition Tool performs browser navigation action ('Go forward in browser history') via Selenium automation. Navigation is an active operation that triggers page loads and external effects.

Verdict

navigate_forward Rate-limited

navigate_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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Selenium, so you can run agents against it safely.

FAQ

Questions about navigate_forward

What does the navigate_forward tool do? +

Go forward in browser history. It is categorised as a Execute tool in the Selenium MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on navigate_forward? +

Register the Selenium MCP server in PolicyLayer and add a rule for navigate_forward: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Selenium. Nothing to install.

What risk level is navigate_forward? +

navigate_forward is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit navigate_forward? +

Yes. Add a rate_limit block to the navigate_forward rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block navigate_forward completely? +

Set action: deny in the PolicyLayer policy for navigate_forward. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides navigate_forward? +

navigate_forward is provided by the Selenium MCP server (scv-consultants/selenium-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
