Capture a screenshot of the active window.
AI agents call capture_screenshot to retrieve information from Zoho Timeline MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool reads/captures visual data from the active window without modifying any data. However, it can capture potentially sensitive information visible on screen (CRM data, credentials, etc.), which raises the severity to medium despite being a read-only operation.

Attacks that exploit this kind of access
Capture a screenshot of the active window. It is categorised as a Read tool in the Zoho Timeline MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Zoho Timeline MCP Server MCP server in PolicyLayer and add a rule for capture_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 Zoho Timeline MCP Server. Nothing to install.
capture_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 capture_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 capture_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.
capture_screenshot is provided by the Zoho Timeline MCP Server MCP server (johnelamont/zoho-timeline-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
