Return statistics: total captures, date range, disk usage.
AI agents call get_stats to retrieve information from Screen Memory without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and retrieves aggregated metadata about screen captures. It does not modify, delete, or execute any operations. The statistics returned are summaries of existing data with no side effects. This is a straightforward read operation with minimal security impact.
From the tool's definition Tool returns statistics (total captures, date range, disk usage) with no modification capability. The description uses read-only verbs: 'Return statistics.'
Attacks that exploit this kind of access
Return statistics: total captures, date range, disk usage. It is categorised as a Read tool in the Screen Memory MCP Server, which means it retrieves data without modifying state.
Register the Screen Memory MCP server in PolicyLayer and add a rule for get_stats: 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 Screen Memory. Nothing to install.
get_stats 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 get_stats 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 get_stats. 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.
get_stats is provided by the Screen Memory MCP server (yonglim2392/screen-memory-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
