Part of the Browser Automation MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents invoke stagehand_navigate to trigger processes or run actions in Browser Automation. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
stagehand_navigate can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. Intercept enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

Navigate to a URL in the browser. Only use this tool with URLs you're confident will work and be up to date. Otherwise, use https://google.com as the starting point. Supports localhost URLs when using cloud browser - automatically tunnels via ngrok.. It is categorised as a Execute tool in the Browser Automation MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Add a rule in your Intercept YAML policy under the tools section for stagehand_navigate. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Browser Automation MCP server.
stagehand_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 stagehand_navigate rule in your Intercept 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 Intercept policy for stagehand_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.
stagehand_navigate is provided by the Browser Automation MCP server (@popoverai/browser-automation). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
