network_commit_changes
Commit pending network interface changes. Network changes are staged and must be committed to take effect. Use checkin_timeout to set a rollback timer — if you do not check in (network_checkin) within that time, changes are automatically rolled back.

What network_commit_changes does on Truenas
AI agents invoke network_commit_changes to trigger actions in Truenas. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why network_commit_changes is rated High
This tool applies staged network configuration changes to the live system. It triggers an external operation (network reconfiguration) that could disrupt connectivity, affect all network-dependent services, and potentially isolate the system if misconfigured.

Attacks that exploit this kind of access
The rule that runs network_commit_changes 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 network_commit_changes, this is the rule to start with:
network_commit_changes stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. 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 network_commit_changes call is checked against it from then on.
Questions about network_commit_changes
Commit pending network interface changes. Network changes are staged and must be committed to take effect. Use checkin_timeout to set a rollback timer — if you do not check in (network_checkin) within that time, changes are automatically rolled back. It is categorised as a Execute tool in the Truenas MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Truenas MCP server in PolicyLayer and add a rule for network_commit_changes: 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.
network_commit_changes is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the network_commit_changes 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 network_commit_changes. 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.
network_commit_changes 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.
