Take a full-screen screenshot. Auto-copies to clipboard.
AI agents call cond_screenshot to retrieve information from TermPipe MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Taking a screenshot retrieves visual information from the display and copies it to clipboard, but does not create, modify, delete, or execute any operations. It is fundamentally a read operation with no side effects on system state.
From the tool's definition Tool description states 'Take a full-screen screenshot. Auto-copies to clipboard.' - this is a read operation that captures visual state without modifying any system state or data.
Attacks that exploit this kind of access
Take a full-screen screenshot. Auto-copies to clipboard. It is categorised as a Read tool in the TermPipe MCP MCP Server, which means it retrieves data without modifying state.
Register the TermPipe MCP server in PolicyLayer and add a rule for cond_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 TermPipe MCP. Nothing to install.
cond_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 cond_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 cond_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.
cond_screenshot is provided by the TermPipe MCP server (wbind-core/termpipe-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
