Implementation Reference
- Handler executes the generate_scale tool: validates root note and scale name, calls MusicTheory.generateScale, formats and returns the scale notes.
case 'generate_scale': InputValidator.validateRootNote(args.root); InputValidator.validateScaleName(args.scale); const scaleNotes = this.theory.generateScale(args.root, args.scale); return `${args.root} ${args.scale} scale: ${scaleNotes.join(', ')}`; - src/server/EnhancedMCPServerFixed.ts:444-455 (registration)Tool registration in getTools(): defines name, description, and input schema for generate_scale.
