The asset-class prefixes (stocks_, crypto_, forex_, options_) help differentiate tools, but within each class there are overlapping functions like get_trades vs get_trades_v3 and multiple snapshot variants (stocks_get_snapshot vs stocks_get_snapshot_all). Descriptions clarify some differences, but agents could easily confuse similar endpoints.
Tool names follow a consistent asset_class_verb_noun pattern with underscores (e.g., stocks_get_ema, crypto_get_aggregate_bars). Minor deviations like options_build_symbol and forex_real_time_conversion don't break the pattern, and the v3 suffix is consistently used.
With 71 tools, this is far beyond a typical MCP server's scope. While the financial domain is broad, the repetitive per-asset-class duplication (e.g., get_rsi for four asset classes) makes the tool set feel bloated. It could be consolidated with a single parameterized endpoint.
The tool set covers core market data (quotes, trades, aggregates, indicators) and reference data for stocks, options, forex, and crypto. However, there are notable gaps: no level 2 order book for stocks/options/forex, no forex/options snapshots, and limited news coverage (only stocks). The presence of v3 variants suggests an inconsistent API surface.
