What replication_create does on Nasbridge
AI agents use replication_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 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.

Attacks that exploit this kind of access
The rule that runs replication_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 replication_create, this is the rule to start with:
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 Nasbridge, apply this rule, and every replication_create call is checked against it from then on.
Questions about replication_create
Create a new replication task. 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 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 Nasbridge. Nothing to install.
replication_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 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.
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.
replication_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.
