agents_set_dpdk · CyPerf MCP Server MCP: Risk & Policy

WHAT IT DOES

What agents_set_dpdk does on CyPerf MCP Server

AI agents invoke agents_set_dpdk to trigger actions in CyPerf MCP Server. 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 IT NEEDS A POLICY

Why agents_set_dpdk needs a policy

Setting DPDK mode reconfigures the network stack of test agents at a low level, switching between kernel and userspace networking. This is an Execute-class action because it triggers an external operational change on agent hardware/software. The blast radius is high because misconfiguration can disrupt network testing infrastructure across multiple agents, potentially taking them offline or making them unreachable.

From the tool's definition 'Set DPDK mode on agents' — changes the Data Plane Development Kit (DPDK) network driver mode on agents, triggering an operational state change that affects network performance behavior

Verdict

agents_set_dpdk Rate-limited

agents_set_dpdk 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches CyPerf MCP Server, so you can run agents against it safely.

FAQ

Questions about agents_set_dpdk

What does the agents_set_dpdk tool do? +

[Agents] Set DPDK mode on agents. It is categorised as a Execute tool in the CyPerf MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on agents_set_dpdk? +

Register the CyPerf MCP Server MCP server in PolicyLayer and add a rule for agents_set_dpdk: 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 CyPerf MCP Server. Nothing to install.

What risk level is agents_set_dpdk? +

agents_set_dpdk is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit agents_set_dpdk? +

Yes. Add a rate_limit block to the agents_set_dpdk 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.

How do I block agents_set_dpdk completely? +

Set action: deny in the PolicyLayer policy for agents_set_dpdk. 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.

What MCP server provides agents_set_dpdk? +

agents_set_dpdk is provided by the CyPerf MCP Server MCP server (keysight/cyperf-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
