[Sessions] List network segments with their IP range settings.
AI agents call sessions_get_network_segments to retrieve information from CyPerf MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists configuration data (network segments and IP range settings) without creating, modifying, deleting, or executing operations. It is a straightforward query operation with minimal risk if misused by an AI agent.
From the tool's definition Tool name contains 'get' and description states 'List network segments' — both indicate data retrieval with no modification or side effects.
Attacks that exploit this kind of access
[Sessions] List network segments with their IP range settings. It is categorised as a Read tool in the CyPerf MCP Server MCP Server, which means it retrieves data without modifying state.
Register the CyPerf MCP Server MCP server in PolicyLayer and add a rule for sessions_get_network_segments: 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.
sessions_get_network_segments 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 sessions_get_network_segments 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 sessions_get_network_segments. 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.
sessions_get_network_segments 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.
sessions_get_network_segments is one line of CyPerf MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
