The sandbox execution environment is well-implemented, using Node.js `vm` module with explicit whitelisting of global objects and `require()` calls to prevent arbitrary code execution outside of specified modules (`@kubernetes/client-node`, `prometheus-query`). Filesystem access for script caching and generated type definitions includes path sanitization to prevent directory traversal. Execution is bound by a configurable timeout. The primary risk lies in the agent's ability to perform actions on the Kubernetes cluster and query Prometheus, with permissions dictated by the `KUBECONFIG` and `PROMETHEUS_URL` provided to the MCP server. `process.env` is exposed inside the sandbox, which could be a vector for sensitive environment variable leakage if unexpected secrets are present.
