    B3.3/5.0

    Scored across 5 tools

    Disambiguation4/5

    Each tool targets a distinct task: conversational chat, general search, documentation lookup, API discovery, and deprecation checking. Search and get_documentation could potentially overlap, but their descriptions make the intended use clear enough.

    Naming Consistency4/5

    Most tools follow a verb_noun pattern (search, get_documentation, find_apis, check_deprecated_code), but 'chat_perplexity' is inconsistent as a compound name and 'search' is a bare verb. The pattern is largely coherent with minor deviations.

    Tool Count5/5

    Five tools is well-scoped for a Perplexity AI integration, covering the primary interaction modes without unnecessary bloat. Each tool serves a meaningful purpose.

    Completeness4/5

    The server covers core capabilities for Perplexity AI: conversational chat, general search, documentation, API discovery, and deprecation checks. A minor gap is the lack of model selection or account-related tools, but these are not essential for typical use.
