AI agents may call browser_use_agent to permanently remove or destroy resources in Hyperbrowser. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. PolicyLayer blocks destructive tools by default and requires explicit human approval before enabling them.
Without a policy, an AI agent could call browser_use_agent in a loop, permanently destroying resources in Hyperbrowser. There is no undo for destructive operations. PolicyLayer blocks this tool by default and only allows it when a human explicitly approves the action.
Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.

This tool employs an open-source browser automation agent optimized specifically for fast, efficient, and cost-effective browser tasks using a cloud browser. It requires explicit, detailed instructions to perform highly specific interactions quickly. Optimal for tasks requiring: - Precise, explicitly defined interactions and actions - Speed and efficiency with clear, unambiguous instructions - Cost-effective automation at scale with straightforward workflows Best suited use cases include: - Explicitly defined registration and login processes - Clearly guided navigation through web apps - Structured, step-by-step web scraping with detailed guidance - Extracting data via explicitly specified browser interactions You must provide extremely detailed step-by-step instructions, including exact elements, actions, and explicit context. Clearly define the desired outcome for optimal results. Returns the completed result or an error message if issues arise. Note: This agent trades off flexibility for significantly faster performance and lower costs compared to Claude and OpenAI agents.. It is categorised as a Destructive tool in the Hyperbrowser MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Hyperbrowser MCP server in PolicyLayer and add a rule for browser_use_agent: 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 Hyperbrowser. Nothing to install.
browser_use_agent is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the browser_use_agent 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 browser_use_agent. 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.
browser_use_agent is provided by the Hyperbrowser MCP server (hyperbrowserai/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
