AI agents use schedule_maintenance_window 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.
This tool creates or modifies a maintenance window configuration, which is reversible (windows can be rescheduled, cancelled, or modified). It does not delete data (Destructive), execute arbitrary operations (Execute), involve financial transactions (Financial), or have permanent side effects.
From the tool's definition Tool description specifies 'Schedule a maintenance window' and accepts parameters for start_time, duration_minutes, operations, and notify_users. This creates a scheduling record that modifies the operational state of the range environment.

Documented attack patterns abuse exactly the kind of access schedule_maintenance_window 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 schedule_maintenance_window:
{
"version": "1",
"default": "deny",
"tools": {
"schedule_maintenance_window": {
"limits": [
{
"counter": "schedule_maintenance_window_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}schedule_maintenance_window 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.

Schedule a maintenance window for the range. Args: start_time: Start time in ISO format duration_minutes: Duration in minutes operations: List of operations to perform during maintenance notify_users: Send notifications to users with access user_id: Optional user ID (admin only) Returns: Maintenance window scheduling result. 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 schedule_maintenance_window: 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.
schedule_maintenance_window 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 schedule_maintenance_window 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 schedule_maintenance_window. 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.
schedule_maintenance_window 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.
