AI agents call windows_ntfs_mft to retrieve information from Velociraptor MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves file metadata from the Windows Master File Table (MFT) using regex filtering on filenames, paths, and timestamps. It is purely informational and read-only, with no side effects or state changes on the target system.
From the tool's definition Tool performs 'Search MFT for filename or path' and 'returns many rows' — a forensic query operation with no modification, deletion, or execution capability. The description explicitly frames it as a 'forensic collection' for artifact retrieval.
Documented attack patterns abuse exactly the kind of access windows_ntfs_mft gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Velociraptor MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for windows_ntfs_mft:
{
"version": "1",
"default": "deny",
"tools": {
"windows_ntfs_mft": {}
}
}windows_ntfs_mft is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search MFT for filename or path on a Windows machine. This is a forensic collection and may return many rows. If failure retry with collect_artifact(). Args: client_id: The Velociraptor client ID. org_id: Optional Velociraptor org ID for multi-tenant deployments. MFTDrive: Target drive letter (default is C:). FileRegex: Regex to match filenames or folders. PathRegex: Regex to match file paths (more costly). DateAfter: Filter for files modified/created after this timestamp. DateBefore: Filter for files modified/created before this timestamp. Fields: Comma-separated string of fields to return. Returns: A result string or error message. It is categorised as a Read tool in the Velociraptor MCP MCP Server, which means it retrieves data without modifying state.
Register the Velociraptor MCP server in PolicyLayer and add a rule for windows_ntfs_mft: 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. Nothing to install.
windows_ntfs_mft 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_ntfs_mft 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_ntfs_mft. 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_ntfs_mft is provided by the Velociraptor MCP server (mgreen27/mcp-velociraptor). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Velociraptor MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
