Parse Prefetch files on a Windows host to identify previously executed programs.
AI agents call windows_execution_prefetch to retrieve information from Velociraptor MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a forensic analysis tool that retrieves and interprets historical execution data from Windows Prefetch artifacts. It has no capability to execute code, modify system state, delete data, or affect financial transactions. The tool purely reads and analyzes existing forensic artifacts, making it a Read category risk.
From the tool's definition Tool parses and reads Prefetch files to identify previously executed programs. Prefetch files are forensic artifacts—read-only analysis of historical execution data.
Attacks that exploit this kind of access
Parse Prefetch files on a Windows host to identify previously executed programs. It is categorised as a Read tool in the Velociraptor MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Velociraptor MCP Server MCP server in PolicyLayer and add a rule for windows_execution_prefetch: 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 Velociraptor MCP Server. Nothing to install.
windows_execution_prefetch 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 windows_execution_prefetch 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 windows_execution_prefetch. 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.
windows_execution_prefetch is provided by the Velociraptor MCP Server MCP server (snoe-findley/mcp-velociraptor). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
