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.
Provides atomic music-theory and MIDI tools for composing, enabling LLMs to chain deterministic steps like scale/chord lookups, degree resolution, rhythm generation, and MIDI rendering.
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.
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.
Enables interactive exploration of guitar chord voicings through an MCP server that provides tools for showing, evaluating, and analyzing chord voicings, with a host-agnostic UI widget for inline fretboard rendering.
