Capture screenshot of the entire screen.
AI agents call capture_full_screen to retrieve information from Auto-Snap MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads/captures the current visual state of the screen. It has no destructive or write side effects. However, it can expose sensitive information visible on screen (passwords, private data, confidential documents), making the severity medium despite being a read operation.

Capture screenshot of the entire screen. It is categorised as a Read tool in the Auto-Snap MCP MCP Server, which means it retrieves data without modifying state.
Register the Auto-Snap MCP server in PolicyLayer and add a rule for capture_full_screen: 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 Auto-Snap MCP. Nothing to install.
capture_full_screen 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_full_screen 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_full_screen. 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_full_screen is provided by the Auto-Snap MCP server (povedaaqui/auto-snap-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
