List Kubernetes persistent volume claims in a namespace
AI agents call list-pvc to retrieve information from Kubernetes MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and retrieves information about persistent volume claims (PVCs) in a Kubernetes namespace. It has no side effects, does not modify or delete data, and does not execute arbitrary operations.
From the tool's definition The tool name is 'list-pvc' and the description states it 'List[s] Kubernetes persistent volume claims in a namespace'. The verb 'list' is a read operation that retrieves information without modifying state.
Attacks that exploit this kind of access
List Kubernetes persistent volume claims in a namespace. It is categorised as a Read tool in the Kubernetes MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Kubernetes MCP Server MCP server in PolicyLayer and add a rule for list-pvc: 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 MCP Server. Nothing to install.
list-pvc 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 list-pvc 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 list-pvc. 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.
list-pvc is provided by the Kubernetes MCP Server MCP server (thekaranpargaie/kube-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
