How to install Kubernetes Troubleshoot

Copy-paste configuration for popular MCP clients.

transport: stdio

Config generated by PluginBench — verify against the source before use.

Environment / auth

KUBECONFIG
required
Path to the kubeconfig inside the container. Must match the mount destination. There is no fallback to ~/.kube/config and no in-cluster config: a missing, unreadable or malformed file is a startup failure rather than a silent downgrade to an ambient credential.
ALLOWED_NAMESPACES
required
Comma-separated namespaces the server may read, e.g. staging,production. Wildcards (* and all) are rejected at startup, and kube-system and kube-public are stripped even if listed. This is defense-in-depth, not the security boundary — the boundary is the ServiceAccount's RBAC bindings.
LOG_LEVEL
DEBUG, INFO, WARNING or ERROR. All logging goes to stderr; stdout carries the JSON-RPC stream exclusively.
API_TIMEOUT_SECONDS
Kubernetes API request timeout. Must be a positive integer.
MAX_LOG_LINES
Maximum log lines any single get_pod_logs call may return. Must be a positive integer; clamped to a hard ceiling of 1000 with a warning.
