List all installed apps with their state.
AI agents call list_apps 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 performs a read-only operation that returns data about the current state of installed apps. It has no side effects, does not create, modify, or delete anything, and does not execute code or transfer funds. It is a straightforward information retrieval operation, making it the lowest severity risk category.
From the tool's definition Tool name 'list_apps' and description 'List all installed apps with their state' indicate a query operation that retrieves information about installed applications without modifying any state or triggering side effects.
Attacks that exploit this kind of access
List all installed apps with their state. 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_apps: 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_apps 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_apps 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_apps. 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_apps 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.
