Copy a blueprint. Args: blueprint_id: ID of the blueprint to copy Returns: Copied blueprint details
AI agents use copy_blueprint to create or update resources in Ludus FastMCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ludus FastMCP environment.
Copying a blueprint creates a new, reversible resource without deleting or modifying the original. This is a Write operation (create/modify data reversibly). Severity is medium because blueprints in a cyber range environment likely define infrastructure configurations; an unintended copy could consume resources or create confusion in range management, but the action is easily reversible by deleting the copy.
From the tool's definition Tool name 'copy_blueprint' and description 'Copy a blueprint' indicates creation of a new resource by duplicating an existing one. Returns 'Copied blueprint details' confirming a new entity is created.
Documented attack patterns abuse exactly the kind of access copy_blueprint gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Ludus FastMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for copy_blueprint:
{
"version": "1",
"default": "deny",
"tools": {
"copy_blueprint": {
"limits": [
{
"counter": "copy_blueprint_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}copy_blueprint 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.

Copy a blueprint. Args: blueprint_id: ID of the blueprint to copy Returns: Copied blueprint details. It is categorised as a Write tool in the Ludus FastMCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Ludus Fast MCP server in PolicyLayer and add a rule for copy_blueprint: 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 Ludus FastMCP. Nothing to install.
copy_blueprint 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 copy_blueprint 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 copy_blueprint. 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.
copy_blueprint is provided by the Ludus Fast MCP server (tjnull/ludus-fastmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
