Add a new host to an inventory with optional variables.

How to control add_host_to_inventory ↓

AI agents use add_host_to_inventory to create or update resources in AAP Enterprise MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AAP Enterprise MCP Server environment.

Medium Risk

This tool creates or modifies inventory records by adding hosts, which is a reversible write operation. While it doesn't delete data (not Destructive) or execute arbitrary code (not Execute), it does alter the automation infrastructure configuration.

From the tool's definition Tool name 'add_host_to_inventory' and description 'Add a new host to an inventory with optional variables' indicate creation/modification of inventory data in Ansible Automation Platform.

Documented attack patterns abuse exactly the kind of access add_host_to_inventory gives an agent:

PolicyLayer is an MCP gateway — it sits between your AI agents and AAP Enterprise MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for add_host_to_inventory:

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

add_host_to_inventory 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 AAP Enterprise MCP Server — 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.
