List resources that might be orphaned (no owner references)
AI agents call orphaned_resources to retrieve information from Kubernetes Monitor 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 Kubernetes cluster information to identify orphaned resources. It has no side effects, does not modify state, and does not execute code or commands. The action is purely informational—listing diagnostic data about the cluster.
From the tool's definition Tool name 'orphaned_resources' performs listing/querying; description states 'List resources that might be orphaned' indicating retrieval of cluster state.
Documented attack patterns abuse exactly the kind of access orphaned_resources gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Kubernetes Monitor, and nothing reaches the server without passing your rules. This is the rule we recommend for orphaned_resources:
{
"version": "1",
"default": "deny",
"tools": {
"orphaned_resources": {}
}
}orphaned_resources is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
List resources that might be orphaned (no owner references). It is categorised as a Read tool in the Kubernetes Monitor MCP Server, which means it retrieves data without modifying state.
Register the Kubernetes Monitor MCP server in PolicyLayer and add a rule for orphaned_resources: 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 Kubernetes Monitor. Nothing to install.
orphaned_resources 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 orphaned_resources 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 orphaned_resources. 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.
orphaned_resources is provided by the Kubernetes Monitor MCP server (vlttnv/k8s-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Kubernetes Monitor, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
