What replication_list does on Nasbridge
AI agents call replication_list to retrieve information from Nasbridge without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why replication_list is rated Low
This tool retrieves and displays information about existing replication tasks without creating, modifying, deleting, or executing any operations. It is a straightforward informational read operation on TrueNAS SCALE configuration data, posing minimal security risk.
From the tool's definition Tool name is 'replication_list' and description states 'List all replication tasks' — a clear query/retrieval operation with no side effects.
Attacks that exploit this kind of access
The rule that runs replication_list 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 replication_list, this is the rule to start with:
replication_list 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 Nasbridge, apply this rule, and every replication_list call is checked against it from then on.
Questions about replication_list
List all replication tasks. It is categorised as a Read tool in the Nasbridge MCP Server, which means it retrieves data without modifying state.
Register the Nasbridge MCP server in PolicyLayer and add a rule for replication_list: 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.
replication_list 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 replication_list 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 replication_list. 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.
replication_list 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.
