WHAT IT DOES

What arvan_helm_install does on ArvanCloud MCP Server

AI agents invoke arvan_helm_install to trigger actions in ArvanCloud MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why arvan_helm_install is rated High

Installing or upgrading a Helm chart executes a deployment operation on a Kubernetes cluster, running workloads and modifying cluster state. This is an active execution of infrastructure changes with potentially broad blast radius—wrong chart versions, misconfigurations, or malicious charts could affect running services across the cluster.

RECOMMENDED RULE

The rule that runs arvan_helm_install safely

arvan_helm_install Rate-limited

arvan_helm_install stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
