List all NFS exports.
AI agents call list_nfs_exports 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 enumerates NFS export configurations without creating, modifying, deleting, or executing actions. It is a pure read operation that gathers information about existing NFS shares. The blast radius of misuse is minimal—exposure of NFS export details could reveal infrastructure topology but poses no immediate operational risk.
From the tool's definition Tool name 'list_nfs_exports' and description 'List all NFS exports' indicate a query/retrieval operation with no data modification or system state changes.
Attacks that exploit this kind of access
List all NFS exports. 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_nfs_exports: 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_nfs_exports 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_nfs_exports 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_nfs_exports. 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_nfs_exports 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.
