update_host

Update host settings including variables, description, or enabled status.

How to control update_host ↓

AI agents use update_host 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 modifies host configuration within Ansible Automation Platform but does not execute commands, delete data irreversibly, or move money. The ability to update 'variables' and 'enabled status' could affect automation behavior if misused by an agent, making it Write rather than Read.

From the tool's definition Tool name 'update_host' with description stating it 'Update[s] host settings including variables, description, or enabled status' indicates modification of host configuration data.

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

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

update_host 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.

What does the update_host tool do? +

Update host settings including variables, description, or enabled status. It is categorised as a Write tool in the AAP Enterprise MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on update_host? +

Register the AAP Enterprise MCP Server MCP server in PolicyLayer and add a rule for update_host: 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 AAP Enterprise MCP Server. Nothing to install.

What risk level is update_host? +

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

Can I rate-limit update_host? +

Yes. Add a rate_limit block to the update_host 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 update_host completely? +

Set action: deny in the PolicyLayer policy for update_host. 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 update_host? +

update_host is provided by the AAP Enterprise MCP Server MCP server (sibilleb/aap-enterprise-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every AAP Enterprise MCP Server tool call.
