The server provides 6 well-named tools with consistent verb_noun naming (get_*) and structured JSON schemas. Descriptions are present for all tools and most parameters. However, there are notable gaps: output schemas are not documented, error handling guidance is missing, and some parameter descriptions lack format/constraint details. The tools are read-only and well-scoped, but the server would benefit from explicit output documentation and recovery guidance for common failure modes.

• Add explicit output schema documentation to all tools. Example for get_company_info: 'Returns: {symbol: string, company_name: string, sector: string, industry: string, market_cap: number, ceo: string}'. This enables LLMs to chain tools and extract fields confidently.
• Add recovery guidance to tool descriptions. Append to get_company_info: 'If company not found by symbol, try searching by partial company name. If API timeout occurs, retry with a shorter date range.'
• Clarify the 'query' parameter across all tools. Append: 'Accepts stock symbol (e.g., AAPL) or company name (e.g., Apple Inc.). Prefer symbol for fastest results. If symbol fails, retry with company name.'
• Document valid values for get_company_financials 'items' parameter as an enum or list. Example: 'Allowed items: revenue, net_income, operating_margin, debt_ratio, eps, dividend_yield. Omit to return all available metrics.'
• Add explicit 'limit' behavior to all tools that use it. Clarify: 'Returns up to this many records. If fewer available, returns what exists. No pagination cursor is provided, for more results, adjust start_date/end_date or item filters.'
• Consider adding status/error field to response schema. E.g., {status: 'success'|'not_found'|'error', error_message?: string, data?: {...}}. This lets clients and LLMs distinguish successful empty results from actual failures.
• Add date format examples to get_company_price_data description. E.g., 'start_date and end_date must be in YYYY-MM-DD format (e.g., 2024-01-15). Default: last 100 trading days.'
