More Details Connect to Claude

The Roman Numeral Converter MCP allows musicians and theorists to bridge the gap between note-based progressions and functional harmonic notation. Using tools like parse_progression_string, resolve_harmonic_function, transpose_progression, and get_chord_metadata, you can instantly transform a sequence of chords (e.g., C-Am-F-G) into its Roman numeral equivalent (I-vi-IV-V). The server also supports automatic transposition, allowing you to shift any progression to a new target key while preserving the underlying harmonic functions and scale degrees.
