Take a PNG screenshot of the current page. By default captures the visible viewport; with fullPage=true, uses CDP Page.getLayoutMetrics and Page.captureScreenshot to capture the full page.
AI agents call take_screenshot to retrieve information from BrowserPilot MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Screenshots are passive observations of page state with no side effects. The tool retrieves visual information about the current browser state without creating, modifying, deleting, or executing any operations on the page or external systems. This is a classic Read operation.
From the tool's definition take_screenshot captures a PNG screenshot of the current page with no modification to the page state or data.
Attacks that exploit this kind of access
Take a PNG screenshot of the current page. By default captures the visible viewport; with fullPage=true, uses CDP Page.getLayoutMetrics and Page.captureScreenshot to capture the full page. It is categorised as a Read tool in the BrowserPilot MCP MCP Server, which means it retrieves data without modifying state.
Register the BrowserPilot MCP server in PolicyLayer and add a rule for take_screenshot: 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 BrowserPilot MCP. Nothing to install.
take_screenshot 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 take_screenshot 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 take_screenshot. 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.
take_screenshot is provided by the BrowserPilot MCP server (sept-7-qi/browserpilot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
