Navigate to a URL, or go forward/back in browser history. Use
AI agents invoke navigate to trigger actions in OpenChrome. 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.
This tool executes browser navigation commands whose effects depend on the provided URL or navigation direction. While it doesn't directly delete data or move money, it can trigger arbitrary page loads and state changes in a real browser environment, potentially visiting malicious sites, phishing pages, or sites that perform unwanted actions.
From the tool's definition Tool 'navigate' performs browser navigation actions (go to URL, forward/back in history) on a 'real Chrome browser' controlled by AI agents.
Documented attack patterns abuse exactly the kind of access navigate gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and OpenChrome, and nothing reaches the server without passing your rules. This is the rule we recommend for navigate:
{
"version": "1",
"default": "deny",
"tools": {
"navigate": {
"limits": [
{
"counter": "navigate_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}navigate 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.

Navigate to a URL, or go forward/back in browser history. Use. It is categorised as a Execute tool in the OpenChrome MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the OpenChrome MCP server in PolicyLayer and add a rule for navigate: 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 OpenChrome. Nothing to install.
navigate is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the navigate 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.
Set action: deny in the PolicyLayer policy for navigate. 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.
navigate is provided by the OpenChrome MCP server (shaun0927/openchrome). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
