This MCP server exhibits severe definition quality issues across all dimensions. While tools are registered with names and basic schemas, the parameter descriptions are frequently placeholder text ('Reference system prompt words'), output schemas are entirely undocumented, and error handling is absent. Tool names follow some verb_noun conventions but lack clarity in distinguishing similar operations (e.g., three tools for 'get...ohlc' with overlapping responsibilities). Parameter descriptions are critically deficient: tools 1-4 use placeholder text instead of actionable descriptions, making it impossible for LLMs to understand parameter semantics. No tool documents its return schema or output format. Security, composition, and error recovery patterns are entirely absent.

• Replace all placeholder parameter descriptions ('Reference system prompt words') with concrete, actionable text. For example, 'full_symbol' should read: 'Full symbol identifier in format STOCK:US:AAPL (exchange:country:ticker) or CRYPTO:GLOBAL:BTCUSD'.
• Document the exact return schema for each tool. Use a consistent format like 'Returns a list of OHLC objects: [{timestamp (ISO 8601), open (float), high (float), low (float), close (float), volume (integer)}]'.
• Convert discrete parameters to enums. For interval, declare: enum=['DAY', 'HOUR', 'M30', 'M15', 'M5', 'M1']. For impact_threshold: enum=['HIGH', 'MEDIUM', 'LOW']. For sentiment_type: enum=['BULLISH', 'BEARISH', 'NEUTRAL'].
• Expand tool descriptions (target 100-200 chars) to clarify differentiation. Example: 'get_live_streaming_ohlc: Retrieves real-time OHLC bars for a single symbol at a specified interval (day/hour/minute). Use this for live price monitoring; for multi-symbol or multi-timeframe analysis, call get_multi_symbol_multi_timeframe_live_streaming_ohlc instead.'
• Rename 'get_custom_abc' to a descriptive name reflecting its actual function (e.g., 'get_abc_indicator', 'get_abc_signal').
• Add error handling guidance to each tool description or create a separate error reference. Example: 'May return invalid_symbol error if the symbol does not exist in the database. Retry with get_custom_symbol_search to verify the symbol.'
• Implement and document pagination for tools that return multiple results. Add offset/limit or cursor parameters and return metadata (total_count, has_more).
