AI agents call list_groups 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 and enumerates groups within an inventory without side effects. It is a read-only operation that queries existing data. The blast radius of misuse is minimal—an AI agent could only gain visibility into inventory group structures, not modify or delete them. Therefore it is classified as Read with low severity.
From the tool's definition Tool name 'list_groups' combined with description 'List all groups in a specific inventory' indicates a query/retrieval operation with no modification or deletion of data.
Documented attack patterns abuse exactly the kind of access list_groups 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 list_groups:
{
"version": "1",
"default": "deny",
"tools": {
"list_groups": {}
}
}list_groups is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all groups in a specific inventory. 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 list_groups: 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.
list_groups 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 list_groups 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 list_groups. 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.
list_groups 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.
