Cluster operations

You have 9 cluster-level tools, mostly read-only.

Reachability and identity

• ping_cluster(cluster) — fast yes/no liveness check. Use this first when troubleshooting any other tool failure.
• get_cluster_info(cluster) — UUID + implementation version. Cheap; safe to call often.
• who_am_i(cluster) — what the cluster sees the current MCP user as (roles, domain). Useful when an AnalyticsAuthError shows up.
