AI agents call browser_scan to retrieve information from Cdp Bridge without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs information retrieval from the active browser tab. It extracts and presents existing page content in a simplified format optimized for LLM consumption, with no capability to modify, delete, or execute operations on the page. The switch_tab_id parameter navigates context but does not alter data.
From the tool's definition Tool description states 'Get simplified HTML content' and 'return tab list without page content' — it retrieves and queries page content without modifying it. The args (tabs_only, text_only) are formatting filters, not side-effect operations.
Documented attack patterns abuse exactly the kind of access browser_scan gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Cdp Bridge, and nothing reaches the server without passing your rules. This is the rule we recommend for browser_scan:
{
"version": "1",
"default": "deny",
"tools": {
"browser_scan": {}
}
}browser_scan is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get simplified HTML content of the active tab plus tab list. The HTML is optimized for LLM consumption (stripped of scripts, styles, invisible elements). Args: tabs_only: Only return tab list without page content (saves tokens). switch_tab_id: Switch to this tab before scanning. text_only: Return plain text instead of simplified HTML. It is categorised as a Read tool in the Cdp Bridge MCP Server, which means it retrieves data without modifying state.
Register the Cdp Bridge MCP server in PolicyLayer and add a rule for browser_scan: 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 Cdp Bridge. Nothing to install.
browser_scan is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the browser_scan 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_scan. 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_scan is provided by the Cdp Bridge MCP server (unagi-cq/cdp-bridge-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
