WHAT IT DOES

What replication_create does on Truenas

AI agents use replication_create to create or update resources in Truenas, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Truenas environment.

RISK

Why replication_create is rated Medium

This tool creates a new replication task, which is a Write operation. However, it carries high severity because replication tasks can move/copy large amounts of data across systems, potentially overwriting destination data, misconfiguring data flows, or consuming significant resources if misused by an AI agent.

RECOMMENDED RULE

The rule that runs replication_create 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 replication_create, this is the rule to start with:

replication_create Rate-limited

replication_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 Truenas, apply this rule, and every replication_create call is checked against it from then on.

FAQ

Questions about replication_create

What does the replication_create tool do? +

Create a new replication task. It is categorised as a Write tool in the Truenas MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on replication_create? +

Register the Truenas MCP server in PolicyLayer and add a rule for replication_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 Truenas. Nothing to install.

What risk level is replication_create? +

replication_create is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit replication_create? +

Yes. Add a rate_limit block to the replication_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.

How do I block replication_create completely? +

Set action: deny in the PolicyLayer policy for replication_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.

What MCP server provides replication_create? +

replication_create 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.
