Render music notation from a JSON score to inline SVG (Verovio + Bravura), round-trippable MusicXML, and base64 MIDI in one call. Includes pre-flight validation with concrete fix suggestions and a curated music-theory knowledge search. Free, open, no auth, sponsored by Gradus School of Music Composition.
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.
MCP server that lets AI agents compose real music through a persistent server-side score, supporting planning, voice writing, verification, and MIDI export.
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 minimal MCP server that composes MIDI, loads Logic Pro factory patches (including Alchemy), and drives transport, turning Logic Pro into an AI-playable instrument.
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.
