Move an Ansible role's scope (Ludus 2.0 only). Args: role_name: Name of the role to move scope: New scope for the role Returns: Move result

How to control move_ansible_role_scope ↓

AI agents use move_ansible_role_scope 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.

Medium Risk

The tool modifies existing Ansible role configuration (scope attribute) rather than reading, executing arbitrary code, or destructively deleting. Moving a scope is a Write operation—it changes state reversibly.

From the tool's definition Tool name 'move_ansible_role_scope' indicates modification of an Ansible role's scope parameter. Description states 'Move an Ansible role's scope', which is a reversible configuration change to an infrastructure automation component.

Documented attack patterns abuse exactly the kind of access move_ansible_role_scope 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 move_ansible_role_scope:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "move_ansible_role_scope": {
      "limits": [
        {
          "counter": "move_ansible_role_scope_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

move_ansible_role_scope 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.

  1. Create a free account and register Ludus FastMCP — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Move an Ansible role's scope (Ludus 2.0 only). Args: role_name: Name of the role to move scope: New scope for the role Returns: Move 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.

How do I enforce a policy on move_ansible_role_scope? +

Register the Ludus Fast MCP server in PolicyLayer and add a rule for move_ansible_role_scope: 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.

What risk level is move_ansible_role_scope? +

move_ansible_role_scope is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit move_ansible_role_scope? +

Yes. Add a rate_limit block to the move_ansible_role_scope 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.

How do I block move_ansible_role_scope completely? +

Set action: deny in the PolicyLayer policy for move_ansible_role_scope. 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.

What MCP server provides move_ansible_role_scope? +

move_ansible_role_scope 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.

Enforce policy on every Ludus FastMCP tool call.
