Implementation Reference

• index.js:647-681 (handler)

  The pulseVibe method implements the core logic of the pulse_vibe tool. It retrieves the specified vibe, creates a pulse record with amplitude, duration, and rhythm step, appends it to the vibe's pulses, and returns a formatted response with visualization.
  pulseVibe(args) { const { vibe_name, amplitude = 0.5, duration = 1 } = args; const vibe = this.vibes.get(vibe_name); if (!vibe) { return { content: [ { type: 'text', text: `❌ Vibe "${vibe_name}" not found.`, }, ], }; } const rhythm = this.rhythms.get(`vibe_${vibe_name}`); const pulse = { timestamp: new Date().toISOString(), amplitude, duration, frequency: vibe.frequency, rhythmStep: rhythm ? rhythm.next() : 1, }; vibe.pulses.push(pulse); return { content: [ { type: 'text', text: `✨ Pulsing vibe "${vibe_name}"\n\nEnergy: ${vibe.energy}\nAmplitude: ${(amplitude * 100).toFixed(0)}%\nDuration: ${duration} beats\n\n${this.visualizePulse(amplitude, vibe.frequency)}\n\nRhythm: ${vibe.rhythm} @ ${pulse.rhythmStep}`, }, ], }; }
• index.js:197-220 (schema)

  The input schema for the pulse_vibe tool defines the expected arguments: vibe_name (required string), optional amplitude (number 0-1), and optional duration (number). This is provided in the ListTools response.
  { name: 'pulse_vibe', description: 'Send a pulse through a vibe', inputSchema: { type: 'object', properties: { vibe_name: { type: 'string', description: 'Name of the vibe', }, amplitude: { type: 'number', minimum: 0, maximum: 1, description: 'Pulse amplitude (0-1)', }, duration: { type: 'number', description: 'Pulse duration in beats', }, }, required: ['vibe_name'], }, },
• index.js:343-344 (registration)

  The switch case in the CallToolRequestSchema handler that routes calls to the pulse_vibe tool to the pulseVibe method.
  case 'pulse_vibe': return this.pulseVibe(args);
