windows_shadow_copies
AI agents call windows_shadow_copies 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.
Shadow copies are forensic data sources used to recover deleted files or previous system states. Accessing them retrieves historical data without modifying or deleting it, making this a Read operation. Severity is medium because unauthorized access to shadow copies could expose sensitive historical data across the system, though the tool itself performs no destructive or side-effect operations.
From the tool's definition Tool name 'windows_shadow_copies' and server context indicate retrieval of Volume Shadow Copy data for forensic analysis. No description provided, but sibling tools like 'collect_artifact' and 'collect_file' are Read operations, establishing the pattern.
Attacks that exploit this kind of access
windows_shadow_copies. 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_shadow_copies: 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_shadow_copies 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_shadow_copies 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_shadow_copies. 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_shadow_copies 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.
