Implementation Reference

• index.js:120-139 (handler)

  The handler function for the 'compress' tool, which processes input data using chosen compression algorithms and returns statistics.

  handleCompress(args) {
    const { data, algorithm = 'auto' } = args;
    if (!data) return { error: 'Missing "data" parameter' };
  
    const result = this.compressData(data, algorithm);
    this.stats.total_compressed++;
    this.stats.total_saved_bytes += result.originalSize - result.compressedSize;
    this.stats.operations++;
  
    return {
      compressed_base64: result.compressed.toString('base64'),
      algorithm: result.algorithm,
      original_size: result.originalSize,
      compressed_size: result.compressedSize,
      ratio: `${result.ratio.toFixed(1)}x`,
      saved_bytes: result.originalSize - result.compressedSize,
      saved_percent: `${((1 - result.compressedSize / result.originalSize) * 100).toFixed(1)}%`,
      ...(result.allResults ? { all_algorithms: result.allResults } : {})
    };
  }

• index.js:309-320 (schema)

  The tool registration schema for 'compress', defining its input parameters and functionality description.

  {
    name: 'compress',
    description: 'Compress text/JSON/CSV data. Returns base64-encoded compressed data with compression ratio. Use algorithm="auto" to pick the best compression.',
    inputSchema: {
      type: 'object',
      properties: {
        data: { type: 'string', description: 'The data to compress (text, JSON, CSV, etc.)' },
        algorithm: { type: 'string', enum: ['auto', 'gzip', 'brotli', 'deflate'], description: 'Compression algorithm. Default: auto (picks best)' }
      },
      required: ['data']
    }
  },
