Each tool targets a distinct action on a distinct concern: creating a new draft, replacing an existing draft, uploading a standalone image, setting an eyecatch, and listing drafts. The only mild overlap is upload_image being auto-invoked by create_draft, but the description explicitly clarifies when to use it, eliminating confusion.

All five tools follow a strict verb_noun snake_case pattern (create_draft, update_draft, upload_image, set_eyecatch, list_drafts). The convention is uniform and predictable throughout.

Five tools is well-scoped for a note draft management server, with each tool earning its place around a clear draft lifecycle. No bloat or redundancy beyond the intentional upload_image helper.

The surface covers create, update, list, image upload, and eyecatch setting, but lacks a delete_draft operation and a get-single-draft fetch (list only returns summary fields). Publishing being manual is a deliberate design choice, so the gap is minor and workable around.
