Critical gaps across all dimensions. Tool naming violates verb-noun convention (add-two-numbers, buy-a-stock, sell-a-stock use hyphens and lack clarity). Two destructive tools (buy/sell) have zero input parameter descriptions, LLMs cannot understand what 'stock' and 'quantity' mean or their constraints. No output schemas documented. No error handling guidance. Schemas present but parameters lack descriptions entirely. This server exposes real financial operations without safeguards.

• Add non-empty descriptions to ALL parameters. For 'stock', specify format (e.g., 'NSE trading symbol, 1-20 uppercase letters'). For 'quantity', specify range (e.g., 'positive integer, 1-10000 shares').
• Document output schemas for all tools. E.g., buy-a-stock should return {order_id: string, status: string, timestamp: ISO8601, quantity: number}.
• Rename tools to verb_noun convention: add_numbers, buy_stock, sell_stock. Use underscores, not hyphens.
• Implement confirmation pattern for destructive tools. Add a 'confirm' parameter or a separate 'confirm_trade' tool that must be called before execution.
• Move API credentials to environment variables or a secure vault. Never hardcode or expose in parameters. Use server-side secret injection.
