What list_roles does on Hpe Networking
AI agents call list_roles to retrieve information from Hpe Networking without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why list_roles is rated Low
This tool retrieves and queries existing wireless/gateway role data without side effects. It performs a read-only operation to enumerate roles in the system. The 'bounded by default' qualifier suggests it has appropriate access controls limiting scope. There is no capability to create, modify, delete, execute commands, or move money, making this a straightforward Read category tool with low severity.
From the tool's definition Tool name is 'list_roles' and description states 'List wireless/gateway roles (bounded by default)' - the verb 'list' and action of retrieving role information with no modification or deletion indicated.
Attacks that exploit this kind of access
The rule that runs list_roles safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Hpe Networking, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_roles, this is the rule to start with:
list_roles is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Hpe Networking, apply this rule, and every list_roles call is checked against it from then on.
Questions about list_roles
List wireless/gateway roles (bounded by default). It is categorised as a Read tool in the Hpe Networking MCP Server, which means it retrieves data without modifying state.
Register the Hpe Networking MCP server in PolicyLayer and add a rule for list_roles: 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 Hpe Networking. Nothing to install.
list_roles 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_roles 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_roles. 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_roles is provided by the Hpe Networking MCP server (secure-ssid/hpe-networking-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
