What truenas does on Nasbridge
AI agents use truenas to create or update resources in Nasbridge, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Nasbridge environment.
Why truenas is rated Medium
An AI agent can call truenas faster than any human can review: one bad instruction and it creates or modifies resources in Nasbridge by the hundred, each call as confident as the last.
Attacks that exploit this kind of access
The rule that runs truenas safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Nasbridge, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For truenas, this is the rule to start with:
truenas stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Nasbridge, apply this rule, and every truenas call is checked against it from then on.
