AI agents call windows_execution_activitiesCache 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 performs forensic artifact retrieval—it queries and returns historical timeline data from Windows activitiesCache.db without modifying, deleting, or executing any operations. It is a read-only forensic query tool. The blast radius is low since misuse would only expose forensic telemetry data already on the endpoint, not trigger new system actions or compromise data integrity.
From the tool's definition Tool retrieves 'Evidence of execution from activitiesCache.db (windows timeline)' and 'Returns: Timeline artifact results as a string'.
Documented attack patterns abuse exactly the kind of access windows_execution_activitiesCache 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_execution_activitiesCache:
{
"version": "1",
"default": "deny",
"tools": {
"windows_execution_activitiesCache": {}
}
} windows_execution_activitiesCache is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Evidence of execution from activitiesCache.db (windows timeline) of system activity on a Windows host. Args: client_id: Velociraptor client ID. org_id: Optional Velociraptor org ID for multi-tenant deployments. Fields: Comma-separated list of fields to return. Returns: Timeline artifact results as a 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_execution_activitiesCache: 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_execution_activitiesCache 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_activitiesCache 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_activitiesCache. 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_activitiesCache 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.
