AI agents call get_host_facts to retrieve information from AAP Enterprise MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves pre-gathered system facts (like CPU, memory, OS details) from a host already managed by Ansible Automation Platform. It performs a read-only query without side effects, making it a Read category tool. Severity is low because exposing host facts has limited direct security impact—the facts themselves are informational about infrastructure already within the AAP ecosystem.
From the tool's definition Tool name 'get_host_facts' and description 'Get gathered facts for a specific host' indicate a retrieval operation with no modification or execution of commands.

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 get_host_facts:
{
"version": "1",
"default": "deny",
"tools": {
"get_host_facts": {}
}
}get_host_facts is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get gathered facts for a specific host. It is categorised as a Read tool in the AAP Enterprise MCP Server MCP Server, which means it retrieves data without modifying state.
Register the AAP Enterprise MCP Server MCP server in PolicyLayer and add a rule for get_host_facts: 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.
get_host_facts is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_host_facts 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 get_host_facts. 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.
get_host_facts 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.
