Server provides 10 tools with reasonable naming and schema coverage, but falls short of production quality in several key areas. Tool names follow verb_noun convention (get_, place_, query_, list_), which is positive. However, descriptions are generic and lack depth needed for LLM decision-making. Parameter descriptions are present but minimal (10-30 chars typical). Output schemas are completely undocumented, no return type specifications visible in code. Error handling is absent from tool definitions. Security considerations around MongoDB credentials and API keys appear to be handled via environment variables (good pattern), but no permission gates or audit logging visible. The paper trading tools (place_buy_order, place_sell_order) lack idempotency and confirmation patterns despite being destructive operations.

• Document return schemas for every tool. Example: 'Returns {symbol: string, price: number, currency: string, timestamp: ISO8601, high_52w: number, low_52w: number}'. This enables LLMs to chain results to downstream tools and extract the right fields.
• Add confirmation patterns to destructive tools: 'place_buy_order: Returns a confirmation_id. Agent must call confirm_order(confirmation_id) within 30s to execute. This prevents accidental duplicate orders from retries.'
• Expand tool descriptions to 100-150 chars with WHEN context. Example: 'Get current stock price, daily change, and 52-week range. Use this when the user asks for real-time pricing or before placing a trade. Returns cached data updated every 15 minutes.'
• Replace example ticker symbols with format constraints in parameter descriptions. Example: 'symbol: uppercase ticker symbol, 1-5 chars, alphanumeric only (e.g., AAPL)' instead of just listing examples.
• Add validation constraints for numeric parameters: 'shares: integer >= 0.01, max 1,000,000. Fractional shares accepted only for fractional trading accounts.' This prevents invalid input and guides LLM reasoning.
• Document pagination for query_portfolio_holdings, query_price_history, query_risk_metrics: 'Results limited to `limit` parameter (max 500). If result count equals limit, additional records exist, call again with offset parameter to fetch next page.'
• Add error recovery guidance: 'If stock symbol not found, returns error_code: INVALID_SYMBOL with available_symbols: [AAPL, MSFT, ...]. Try search_symbols() first for partial matches.'

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