Chords, scales, transposition, capo and tempo maths, with links to free interactive music tools.
Scored across 6 tools
Each tool has a clearly distinct purpose: bpm_to_ms handles tempo conversions, capo_finder suggests capo positions, chord_info provides chord details, open_music_tool opens interactive tools, scale_info describes scales, and transpose_chords transposes progressions. There is no overlap in functionality, making it easy for an agent to select the right tool.
All tools use a consistent snake_case verb_noun or noun_verb pattern (e.g., bpm_to_ms, capo_finder, chord_info, open_music_tool, scale_info, transpose_chords). The naming is predictable and follows a single convention throughout.
With 6 tools, the set is well-scoped for a music utilities server. Each tool covers a distinct and useful music-related task without redundancy, and the count is neither too thin nor too heavy.
The tool surface covers core music tasks like tempo conversion, chord/scale info, transposition, and capo suggestions, but lacks tools for related operations such as chord progression analysis, instrument tuning specifics beyond links, or integration with other music theory concepts. Minor gaps exist, but the essentials are present.
