Parse Windows Prefetch files to determine program execution history, run counts, and last execution times. Can parse a single .pf file or an entire Prefetch directory. Supports pagination.
AI agents call disk_parse_prefetch to retrieve information from Windows Forensics MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads and parses existing Prefetch files on disk to extract forensic data about program execution history. It performs no writes, deletions, or external operations — purely retrieval and analysis. Severity is medium because it accesses potentially sensitive execution history data that could reveal user activity patterns, though it causes no side effects.

Documented attack patterns abuse exactly the kind of access disk_parse_prefetch gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Windows Forensics MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for disk_parse_prefetch:
{
"version": "1",
"default": "deny",
"tools": {
"disk_parse_prefetch": {}
}
}disk_parse_prefetch is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Parse Windows Prefetch files to determine program execution history, run counts, and last execution times. Can parse a single .pf file or an entire Prefetch directory. Supports pagination. It is categorised as a Read tool in the Windows Forensics MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Windows Forensics MCP Server MCP server in PolicyLayer and add a rule for disk_parse_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 Windows Forensics MCP Server. Nothing to install.
disk_parse_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 disk_parse_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 disk_parse_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.
disk_parse_prefetch is provided by the Windows Forensics MCP Server MCP server (x746b/winforensics-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Windows Forensics MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
