List Helm releases
AI agents call helm-list 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 lists/retrieves Helm release information with no side effects. It is a simple informational query (helm list) that does not create, modify, delete, or execute any operations. The blast radius of misuse is minimal — an attacker could only discover what Helm releases are deployed, which is low-sensitivity metadata in most Kubernetes environments.
From the tool's definition Tool name and description indicate 'List Helm releases' — a read-only query operation that retrieves information about deployed Helm charts without modifying any cluster state.
Attacks that exploit this kind of access
List Helm releases. 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 helm-list: 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.
helm-list 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 helm-list 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 helm-list. 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.
helm-list 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.
