What ssh_config does on Truenas
AI agents call ssh_config to retrieve information from Truenas without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why ssh_config is rated Low
This tool retrieves and returns existing SSH configuration data without modifying, deleting, or executing any operations. It is a straightforward information retrieval action with no blast radius if misused by an AI agent, as it cannot alter system state or trigger external operations.
From the tool's definition Tool name 'ssh_config' combined with description 'Get the current SSH service configuration' indicates a retrieval operation with no side effects. The verb 'Get' explicitly denotes a read-only query.
Attacks that exploit this kind of access
The rule that runs ssh_config safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Truenas, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For ssh_config, this is the rule to start with:
ssh_config is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Truenas, apply this rule, and every ssh_config call is checked against it from then on.
Questions about ssh_config
Get the current SSH service configuration. 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 ssh_config: 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.
ssh_config 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 ssh_config 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 ssh_config. 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.
ssh_config 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.
