api_key_create
Create a new API key for programmatic access to the TrueNAS API. The key value is redacted from the response and TrueNAS never shows it again, so create a key you need to copy in the TrueNAS UI instead.

What api_key_create does on Nasbridge
AI agents use api_key_create 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 api_key_create is rated Medium
Creates persistent credentials enabling programmatic system access; misuse grants attacker lasting authenticated access to TrueNAS infrastructure.
From the tool's definition Create new API key for programmatic access to TrueNAS API.
Attacks that exploit this kind of access
The rule that runs api_key_create 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 api_key_create, this is the rule to start with:
api_key_create 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 api_key_create call is checked against it from then on.

Create a new API key for programmatic access to the TrueNAS API. The key value is redacted from the response and TrueNAS never shows it again, so create a key you need to copy in the TrueNAS UI instead. It is categorised as a Write tool in the Nasbridge MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Nasbridge MCP server in PolicyLayer and add a rule for api_key_create: 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 Nasbridge. Nothing to install.
api_key_create is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the api_key_create 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 api_key_create. 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.
api_key_create is provided by the Nasbridge MCP server (maverick0628/nasbridge). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
