kafka-sentinel-mcp defines 6 read-only tools with clear, domain-specific names (cluster_health, consumer_lag, topic_audit, partition_state, replay_readiness, list_topics). All tools have descriptions (avg ~100 chars) and input schemas with typed parameters. However, output schemas are not documented, LLMs cannot predict response structure. Parameter descriptions are minimal (e.g., 'Consumer group ID' lacks context on format/constraints). Error handling is present (TopicNotFoundError, _permission_denied) but not comprehensive, no guidance on retryability or recovery steps. Tools follow single-responsibility principle and are well-named with action verbs, but lack the depth of documentation and output specification expected for production-grade tools.

• Document output schemas for all tools. Include field names, types, and descriptions. E.g., cluster_health should specify: {broker_count: int, controller_id: int, under_replicated_partitions: int, offline_partitions: int}.
• Enhance parameter descriptions with format constraints. E.g., 'Consumer group ID (alphanumeric, 1-256 chars, no spaces)' and 'Topic name (alphanumeric + hyphens, 1-249 chars)'.
• Add pagination to list_topics: accept limit (1-100, default 20) and offset parameters; return total_count and next_offset in response.
• Expand error handling to cover timeout, broker unavailable, and partial ACL denial scenarios. Return structured errors with retryability classification and recovery hints.
• Add tool selection guidance in descriptions. E.g., 'Use topic_audit to check replication/durability config; use partition_state to inspect leader/ISR distribution.'

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
