Each tool targets a distinct resource and action: notebook management, source operations, research tasks, artifact creation, query, and auth. Despite many artifact creation tools, each clearly specifies its output type (audio, video, infographic, etc.), so no two tools appear to do the same thing.

Most tools follow a resource_action pattern (e.g., notebook_create, source_delete, report_create), which is consistent. A few outliers like save_auth_tokens and refresh_auth use action_resource order, and research_status and studio_status are noun_noun compounds, but these are minor deviations within a largely coherent scheme.

At 27 tools, the server exceeds the 25-tool threshold for 'too many'. The count is inflated by 8 separate artifact creation tools that could be unified into a single tool with a type parameter, and the three add-source tools similarly could be consolidated. While the server covers a broad domain, the tool surface is heavier than necessary.

The tool set covers the full lifecycle for notebooks (create, read, list, rename, delete), sources (add three types, delete, describe, get content, sync), research (start, status, import), and artifacts (create and check status). Minor gaps exist such as no explicit list_sources tool (though notebook_get provides sources) and no update_source, but these are manageable workarounds.
