AI agents invoke batch_power_on_hosts to trigger actions in Ludus FastMCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
Powering on hosts triggers external infrastructure operations affecting potentially many VMs simultaneously. It fits the Execute category (triggering external operations). The batch nature and cyber range context give it high severity, as misuse could spin up unintended infrastructure at scale. Description is empty so confidence is reduced.
From the tool's definition Tool name 'batch_power_on_hosts' suggests powering on multiple hosts in a cyber range environment. Description is empty, lowering confidence.

Documented attack patterns abuse exactly the kind of access batch_power_on_hosts 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 batch_power_on_hosts:
{
"version": "1",
"default": "deny",
"tools": {
"batch_power_on_hosts": {
"limits": [
{
"counter": "batch_power_on_hosts_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}batch_power_on_hosts stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

batch_power_on_hosts. It is categorised as a Execute tool in the Ludus FastMCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Ludus Fast MCP server in PolicyLayer and add a rule for batch_power_on_hosts: 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.
batch_power_on_hosts is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the batch_power_on_hosts 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 batch_power_on_hosts. 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.
batch_power_on_hosts 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.
