What port_bounce does on Hpe Networking
AI agents invoke port_bounce to trigger actions in Hpe Networking. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why port_bounce is rated High
Bouncing a port forces a link reset on network infrastructure, temporarily taking down connected devices/sessions. This is an external operation with real network impact (service disruption) but is generally recoverable, placing it in Execute rather than Destructive. However, misuse could affect many downstream users if applied to uplinks or critical ports, warranting high severity.
From the tool's definition 'Link-reset (bounce) switch/gateway ports' — triggers an external network operation that disrupts active port connectivity
Attacks that exploit this kind of access
The rule that runs port_bounce 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 port_bounce, this is the rule to start with:
port_bounce stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. 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 port_bounce call is checked against it from then on.
Questions about port_bounce
Link-reset (bounce) switch/gateway ports (async, polls ~60s). It is categorised as a Execute tool in the Hpe Networking MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Hpe Networking MCP server in PolicyLayer and add a rule for port_bounce: 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.
port_bounce is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the port_bounce 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 port_bounce. 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.
port_bounce 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.
