This server has 2 tools with severe definition quality issues. Both tools have minimal descriptions (under 20 characters for practical detail), no documented output schemas, and extremely basic parameter documentation. The descriptions are vague: 'Returns a full summary of processed Kafka messages' and 'Returns the count for a specific action like 'login'' lack actionable context for LLM selection. Neither tool documents what the response structure contains. The get_usage_metrics tool accepts empty input {} but lacks any parameter documentation. The count_action tool has a single string parameter with a description that relies on an example ('login') rather than explaining the valid domain of action names. No error handling guidance is documented. No tool declares permissions, idempotency guarantees, or recovery paths. The codebase shows basic FastMCP usage but does not meet production quality standards for agentic tool composition.

• Add explicit output schemas. Document that get_usage_metrics returns {total: int, breakdown: {[action_name: string]: int}} and count_action returns {action_name: string, count: int}.
• Expand descriptions to 50-150 characters. Example: get_usage_metrics: 'Retrieves aggregate and per-action message counts from the Kafka ingestor. Returns total messages processed and a breakdown by action type (enter, exit, think, play).' count_action: 'Returns the count of messages for a specific action. Valid actions: enter, exit, think, play. Returns 0 if the action has not been seen.'
• Document valid action names as an enum or explicit list in count_action parameter description. Add: 'action_name must be one of: enter, exit, think, play. Returns 0 if the action name is not recognized.'
• Add error handling: 'If no data has been ingested, get_usage_metrics returns total=0 and empty breakdown. If count_action receives an unrecognized action, it returns 0; use get_usage_metrics to discover valid action names.'
• Add tool annotations declaring these are read-only operations with no side effects. Add idempotentHint: true to both tools.
• Document dependencies: 'These tools require the Kafka-to-Redis ingestor to be running. If results are empty, verify the ingestor has started and messages have been published to the configured topic.'

Inferred effective spec: <=2025-11-25.

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