Server has 4 tools with basic schemas and descriptions, but significant quality gaps. All tools have descriptions (10-200 chars, within baseline range) and input schemas with typed parameters. However, naming lacks clarity (ingest_realtime_webhook vs ingest_batch_api_poll are similar; process_lambda_pipeline is vague). No output schemas documented. Error handling is minimal, responses are JSON strings without structured error guidance. Parameters lack enums for constrained values (e.g., target_warehouse should be enum, not free string). No tool annotations (readOnlyHint/destructiveHint). Security concern: WEBHOOK_SECRET_KEY hardcoded in source. Missing pagination for export_to_data_warehouse. Per-tool average: 42/100.

• Document output schemas for all tools. Specify returned fields, types, and whether results are paginated. Example: ingest_realtime_webhook returns {status: string, timestamp: string, current_queue_size: integer}.
• Move WEBHOOK_SECRET_KEY to environment variable (e.g., os.getenv('WEBHOOK_SECRET_KEY')). Never hardcode secrets in source.
• Rename process_lambda_pipeline to migrate_hot_to_cold or process_hot_tier_migration to clarify the action.
• Add enum constraint to target_warehouse parameter: enum=['SNOWFLAKE', 'CLICKHOUSE', 'BIGQUERY']. Update description to list valid options.
• Implement structured error responses with error_code, message, and recovery_hint fields. Example: {error_code: 'BACKPRESSURE_LIMIT_EXCEEDED', message: '...', recovery_hint: 'Retry in 30 seconds or reduce batch size.'}.
