List all device groups (scopeId, scopeName, description).
AI agents call list_device_groups to retrieve information from API-Central without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries existing device group information without creating, modifying, or deleting any data. It is a straightforward read operation that poses minimal risk if called by an AI agent, as it only exposes existing configuration metadata.
From the tool's definition Tool name is 'list_device_groups' and description states it 'List all device groups' with metadata fields (scopeId, scopeName, description). The verb 'list' indicates data retrieval with no side effects.
Attacks that exploit this kind of access
List all device groups (scopeId, scopeName, description). It is categorised as a Read tool in the API-Central MCP Server, which means it retrieves data without modifying state.
Register the API-Central MCP server in PolicyLayer and add a rule for list_device_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 API-Central. Nothing to install.
list_device_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_device_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_device_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_device_groups is provided by the API-Central MCP server (secure-ssid/centralmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
