Take a screenshot of the current page. savePath is the directory to save to (default: ~/Downloads). Returns the screenshot image.
AI agents call screenshot to retrieve information from TgeBrowser MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Screenshots are read-only operations that retrieve visual information from the current browser state. While the tool saves output to disk (savePath parameter), this is a benign artifact of the retrieval operation, not a write operation that modifies application state or data. No reversible modifications, code execution, destructive actions, or financial operations are involved.
From the tool's definition Tool name 'screenshot' and description 'Take a screenshot of the current page' indicate data retrieval with no side effects.
Attacks that exploit this kind of access
Take a screenshot of the current page. savePath is the directory to save to (default: ~/Downloads). Returns the screenshot image. It is categorised as a Read tool in the TgeBrowser MCP Server MCP Server, which means it retrieves data without modifying state.
Register the TgeBrowser MCP Server MCP server in PolicyLayer and add a rule for 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 TgeBrowser MCP Server. Nothing to install.
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 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 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.
screenshot is provided by the TgeBrowser MCP Server MCP server (tuguang2025/tgebrowser-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
