Scored across 8 tools
Every tool has a clearly distinct purpose focused on different aspects of market data retrieval. Tools like get_aggregates (historical bars), get_daily_open_close (daily prices), get_latest_quote (real-time quote), and get_snapshot (current state) all serve unique functions without overlap, making it easy for an agent to select the right tool.
All tools follow a consistent verb_noun pattern with 'get_' or 'list_' prefixes, using snake_case throughout. This predictability (e.g., get_aggregates, list_tickers) makes the tool set easy to navigate and understand at a glance.
With 8 tools, this server is well-scoped for a financial market data domain, covering essential operations like real-time quotes, historical data, news, and ticker listings. Each tool earns its place without feeling excessive or insufficient for the purpose.
The tool set provides comprehensive coverage for market data retrieval, including real-time, historical, and informational aspects. A minor gap exists in lacking update/delete operations, but this is appropriate for a read-only data source, and agents can work around this limitation effectively.
