List endpoint groups in an application profile
AI agents call list_endpoint_groups to retrieve information from ACI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about existing endpoint groups (EPGs) in a network fabric without modifying, deleting, or executing any operations. It is a pure read operation that retrieves configuration data from the Cisco ACI APIC REST API. Low severity because misuse by an AI agent would only expose existing network configuration data, not cause infrastructure changes or data loss.
From the tool's definition Tool name 'list_endpoint_groups' and description 'List endpoint groups in an application profile' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
List endpoint groups in an application profile. It is categorised as a Read tool in the ACI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ACI MCP Server MCP server in PolicyLayer and add a rule for list_endpoint_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 ACI MCP Server. Nothing to install.
list_endpoint_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_endpoint_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_endpoint_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_endpoint_groups is provided by the ACI MCP Server MCP server (jim-coyne/aci_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
