C2.5/5.0

Scored 2026-04-18 10:00 across 53 tools

Disambiguation4/5

Most tools have distinct purposes targeting specific asset classes (e.g., stocks, crypto, futures) or data types (e.g., aggregates, snapshots, lists), with clear boundaries. However, some overlap exists between similar 'list' and 'get' functions (e.g., list_aggs vs get_aggs) that could cause minor confusion, though descriptions help differentiate them.

Naming Consistency5/5

Tool names follow a highly consistent verb_noun pattern throughout, using 'get_' for single-item retrieval and 'list_' for collections, with clear and descriptive nouns (e.g., get_ticker_details, list_futures_contracts). There are no deviations in naming conventions, making the set predictable and readable.

Tool Count2/5

With 53 tools, the count is excessive for a single server, making it overwhelming and difficult for agents to navigate efficiently. While the domain (financial data) is broad, this many tools suggests poor scoping and could lead to usability issues, as typical well-scoped servers have 3-15 tools.

Completeness5/5

The tool surface provides comprehensive coverage for financial data retrieval, including stocks, crypto, forex, futures, and market metadata, with full CRUD-like operations (mostly read/list functions) and no apparent gaps. It supports diverse workflows from real-time quotes to historical analysis and auxiliary data like news or holidays.
