Get status of known cluster nodes on the network.
AI agents call get_cluster_nodes 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 queries and returns the status of existing cluster nodes without any side effects. It is a read-only operation that retrieves network infrastructure data. The 'get_' prefix and passive voice 'Get status' confirm no actions are performed on the infrastructure itself.
From the tool's definition Tool name 'get_cluster_nodes' and description 'Get status of known cluster nodes on the network' indicate pure information retrieval with no modification, creation, or execution capability.
Attacks that exploit this kind of access
Get status of known cluster nodes on the network. 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_cluster_nodes: 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_cluster_nodes 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_cluster_nodes 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_cluster_nodes. 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_cluster_nodes 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.
