Get the full network topology including cluster nodes, known devices, and unknown devices.
AI agents call get_network_topology to retrieve information from Network Scanner MCP 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 network infrastructure data without modifying or executing actions on that data. It fits the Read category (retrieves or queries data; no side effects). However, severity is high rather than low because network topology information is sensitive infrastructure data that could be leveraged by a compromised AI agent for reconnaissance, lateral movement planning, or targeted attacks.
From the tool's definition Tool is described as 'Get the full network topology' which retrieves network structure and device information. The action verb 'Get' and lack of any modification/creation/deletion language indicates read-only behavior.
Attacks that exploit this kind of access
Get the full network topology including cluster nodes, known devices, and unknown devices. It is categorised as a Read tool in the Network Scanner MCP MCP Server, which means it retrieves data without modifying state.
Register the Network Scanner MCP server in PolicyLayer and add a rule for get_network_topology: 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 Network Scanner MCP. Nothing to install.
get_network_topology 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 get_network_topology 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 get_network_topology. 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.
get_network_topology is provided by the Network Scanner MCP server (marc-shade/network-scanner-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
