Implementation Reference

• src/server/EnhancedMCPServerFixed.ts:900-905 (handler)

  Handler function for the 'stretch' tool. Validates the factor, retrieves the current pattern, appends .slow(factor) to stretch it temporally, writes the modified pattern, and returns a confirmation message.

  case 'stretch':
    InputValidator.validateGain(args.factor); // Positive number, use gain validator for simplicity
    const toStretch = await this.getCurrentPatternSafe();
    const stretched = toStretch + `.slow(${args.factor})`;
    await this.writePatternSafe(stretched);
    return `Stretched by factor of ${args.factor}`;

• src/server/EnhancedMCPServerFixed.ts:171-181 (registration)

  Tool registration in getTools() method, including name, description, and input schema requiring a numeric 'factor' parameter.

  {
    name: 'stretch',
    description: 'Time stretch pattern',
    inputSchema: {
      type: 'object',
      properties: {
        factor: { type: 'number', description: 'Stretch factor' }
      },
      required: ['factor']
    }
  },

• src/server/EnhancedMCPServerFixed.ts:171-181 (schema)

  Input schema definition for the 'stretch' tool, specifying the required 'factor' as a number.

  {
    name: 'stretch',
    description: 'Time stretch pattern',
    inputSchema: {
      type: 'object',
      properties: {
        factor: { type: 'number', description: 'Stretch factor' }
      },
      required: ['factor']
    }
  },
