Each tool has a clearly distinct purpose with no ambiguity: get_niivue_api fetches API method details, get_niivue_doc fetches doc page content, get_niivue_overview returns the overview, list_niivue_docs lists docs, search_niivue_api searches API methods, and search_niivue_docs searches documentation. The tools are well-differentiated by their target resource (API vs. docs) and action (get vs. list vs. search).

All tool names follow a consistent verb_noun pattern with 'niivue' as a prefix, using snake_case throughout. The verbs (get, list, search) are applied predictably to the nouns (api, doc, overview, docs), making the naming highly consistent and readable.

With 6 tools, the server is well-scoped for its purpose of accessing Niivue documentation and API information. Each tool earns its place by covering distinct aspects like fetching, listing, and searching, without being too sparse or bloated, which is ideal for a documentation-focused server.

The tool set provides comprehensive coverage for accessing and searching Niivue documentation and API details, with no obvious gaps for the stated purpose. Minor gaps might include lack of update or delete operations, but these are not expected in a read-only documentation context, so the surface is nearly complete.
