List recent system jobs with status, progress, and errors.
AI agents call list_jobs to retrieve information from Truenas Ws without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays information about system jobs. It performs a query operation that does not create, modify, delete, execute commands, or trigger external operations. The read-only nature and absence of any state-changing effects clearly place it in the Read category with low severity, as misuse would only surface information that an AI agent might already have access to or that would not cause harm.
From the tool's definition Tool name 'list_jobs' and description 'List recent system jobs with status, progress, and errors' indicate a retrieval operation with no side effects. The verb 'list' is a canonical Read operation that queries existing data without modification.
Attacks that exploit this kind of access
List recent system jobs with status, progress, and errors. It is categorised as a Read tool in the Truenas Ws MCP Server, which means it retrieves data without modifying state.
Register the Truenas Ws MCP server in PolicyLayer and add a rule for list_jobs: 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 Ws. Nothing to install.
list_jobs 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 list_jobs 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 list_jobs. 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.
list_jobs is provided by the Truenas Ws MCP server (thoriphes/truenas-ws-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
