Financial market intelligence — real-time stock quotes (Twelve Data), market indices (S&P 500, VIX, NASDAQ, gold, oil via FRED), and SEC 13F institutional holdings. First traditional market data API on x402.
Scored across 3 tools
Each tool targets a completely distinct data domain: institutional holdings, market indices, and stock quotes. There is no overlap or ambiguity in their purposes.
All tool names follow a consistent 'get_' prefix followed by a descriptive noun phrase (institutional_holdings, market_indices, stock_quotes). The pattern is uniform and predictable.
With only 3 tools, the server is tightly scoped and each tool provides a distinct, valuable capability for market data retrieval. This is well within the typical 3-15 range and feels appropriate for a focused utility.
The tool surface covers key market data needs, but lacks historical price data or company fundamentals, which are common adjacent use cases. These are minor gaps that agents can work around by combining the existing tools or using external data.
