For local development you don't need a dedicated MCP server for CockroachDB, Prometheus, or Jaeger. Just exec into the container and run commands directly. SQL in cockroach, wget the Prometheus HTTP API, same for Jaeger. 😏

curl isn't available, but wget is. kubectl exec -n observability prometheus-k8s-0 -- wget -qO 'localhost:9090/api/v1/query?query=up{job="api"}'

All of this runs through the colima MCP server in Claude Code. claude mcp add-json colima '{"command":"npx","args":["-y","kubernetes-mcp-server@latest"],"env":{"KUBECONFIG":"'${HOME}'/.kube/config"}}' I've allow listed `mcp__colima__*`. Local VM, fully isolated. 🤌
