Critical failures across all dimensions. No input schemas visible in source code, cannot verify parameter types, constraints, or structure. Tool descriptions are present but extremely generic (10-40 chars), providing minimal LLM guidance. No output schemas documented. No error handling patterns. No parameter descriptions. Tools appear to be inferred from runner.py configuration rather than explicitly registered with full definitions. This server would require complete schema and documentation overhaul before production use.

• Create explicit MCP tool registration with full JSON Schema for all 19 tools. Include type definitions (string, number, boolean, object, array) and constraints (enum, minLength, maxLength, minimum, maximum, pattern) for every parameter.
• Expand tool descriptions to 50-200 characters. For each tool, answer: What does it do? When should the LLM call it instead of similar tools? What does it return? Example: 'Retrieve current portfolio holdings and positions. Use this to check open trades, entry prices, and current P&L before making trading decisions. Returns list of positions with symbol, side, size, entry price, and current value.'
• Document output schemas for all tools. Specify returned fields, their types, and whether results are paginated. Example for get_portfolio: '{positions: [{symbol: string, side: string, size: number, entry_price: number, current_price: number, pnl: number}], total_equity: number, available_margin: number}'
• Add parameter descriptions for all inputs. For execute_order, document: symbol (trading pair, e.g. 'BTC/USD'), side (enum: 'buy'|'sell'), size (positive number, units of base asset), order_type (enum: 'market'|'limit'), price (required if limit order, omit for market).
• Implement error handling with recovery guidance. For execute_order failures, return: '{error: 'Insufficient margin', required_margin: 1500, available_margin: 1200, suggestion: 'Reduce order size or close a position to free margin'}' instead of a bare error code.
