Each tool has a clearly distinct purpose with no overlap: get_ietf_doc retrieves specific documents, list_ietf_docs_number provides metadata about document count, and search_ietf_rfc_by_keyword enables keyword-based discovery. The descriptions clearly differentiate between retrieval, counting, and searching functions.

The tools follow a mostly consistent verb_noun pattern with get_, list_, and search_ prefixes, though 'list_ietf_docs_number' deviates slightly by including 'number' in the name rather than using a more conventional pattern like 'count_ietf_docs'. The snake_case convention is consistently applied throughout.

With only 3 tools, the server feels somewhat thin for an IETF/RFC document access service. While the tools cover basic retrieval and search, the count is borderline minimal for what could reasonably include operations like filtering by date, accessing drafts, or managing document collections.

The toolset covers fundamental document access (get, count, search) but has notable gaps for a complete IETF document service. Missing operations include filtering by date or status, accessing IETF drafts (not just RFCs), and more advanced search capabilities beyond simple keyword matching in titles.
