    Scored across 3 tools

    Disambiguation5/5

    Each tool serves a clear, distinct purpose: searching for packages, fetching details of a specific package, and comparing alternatives. No overlap in functionality.

    Naming Consistency5/5

    All tool names follow a consistent verb_noun pattern: search_packages, get_package, compare_packages. The pattern is uniform and predictable.

    Tool Count4/5

    With only 3 tools, the server is well-scoped for its purpose. Each tool is essential and non-redundant, though the count is on the lower end of the ideal range.

    Completeness4/5

    The tool set covers the core workflow of discovering and evaluating npm packages. Minor gaps include lack of package version history or no ability to get all versions, but the primary workflow is complete.
