MCP server for vibe coding with music, enabling format conversion (LilyPond, MusicXML, MIDI, ABC, etc.), audio-to-sheet transcription, and transposition with robust fallback outputs.
A composition-focused server built on music21 for generative music workflows, enabling melody generation, musical transformations, chord reharmonization, counterpoint creation, and MIDI export through constraint-based algorithmic composition tools.
Deterministic music-theory MCP server and API for AI agents — analyze chords, run Roman-numeral analysis, generate voicings, and reharmonize progressions. Computed from music theory, not hallucinated.
A comprehensive MCP server for querying the MusicBrainz database, providing tools to search for artists, releases, recordings, and browse music metadata.
MCP server that transcribes songs into multi-track General MIDI files, identifying instruments and structuring tracks. Accepts audio files and manages transcription jobs with queue and ETA.
An MCP server exposing @playbykey/theory as AI-callable music theory tools. Compute chords, scales, progressions, transpositions, and MIDI/frequency conversions instead of having your AI assistant guess at music theory from training data.
