Get time-series reporting data for one or more graphs (CPU, memory, disk, network, etc.). Use reporting_graphs first to discover available graph names and identifiers.
AI agents call reporting_get_data to retrieve information from Truenas without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves historical system performance metrics and monitoring data. It is a read-only query operation that does not modify, execute, delete, or commit any financial transactions. The data retrieved is informational and used for analysis/monitoring purposes only. The blast radius of misuse is minimal—an attacker could gather system performance information but cannot affect system state or operations.
From the tool's definition Tool description states 'Get time-series reporting data' which is a retrieval operation for metrics (CPU, memory, disk, network usage). The verb 'Get' and the context of querying existing graph data indicates no modifications, deletions, or side effects.
Documented attack patterns abuse exactly the kind of access reporting_get_data gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Truenas, and nothing reaches the server without passing your rules. This is the rule we recommend for reporting_get_data:
{
"version": "1",
"default": "deny",
"tools": {
"reporting_get_data": {}
}
}reporting_get_data is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get time-series reporting data for one or more graphs (CPU, memory, disk, network, etc.). Use reporting_graphs first to discover available graph names and identifiers. It is categorised as a Read tool in the Truenas MCP Server, which means it retrieves data without modifying state.
Register the Truenas MCP server in PolicyLayer and add a rule for reporting_get_data: 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 Truenas. Nothing to install.
reporting_get_data 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 reporting_get_data 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 reporting_get_data. 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.
reporting_get_data is provided by the Truenas MCP server (spranab/truenas-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Truenas, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
