Take a screenshot of the current page
AI agents call browser_screen_capture to retrieve information from Playwright MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only reads and returns the current visual state of the page as an image. It has no side effects, does not modify any data, and cannot be used to trigger operations. Screenshots are purely observational, making this a Read-category tool with low severity.
From the tool's definition 'Take a screenshot of the current page' — purely captures/reads the current visual state of the browser
Attacks that exploit this kind of access
Take a screenshot of the current page. It is categorised as a Read tool in the Playwright MCP MCP Server, which means it retrieves data without modifying state.
Register the Playwright MCP server in PolicyLayer and add a rule for browser_screen_capture: 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 Playwright MCP. Nothing to install.
browser_screen_capture 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_screen_capture 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_screen_capture. 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_screen_capture is provided by the Playwright MCP server (manishamishraacc/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
