Image Converter MCP Server

Instructions

Implementation Reference

• src/index.ts:278-288 (handler)

  The MCP tool handler for 'list_supported_formats' that invokes the ImageConverter's getSupportedFormats() method and formats the response as text content listing input and output formats.

  case 'list_supported_formats': {
    const formats = this.converter.getSupportedFormats();
    return {
      content: [
        {
          type: 'text',
          text: `支持的图片格式：\n输入格式：${formats.input.join(', ')}\n输出格式：${formats.output.join(', ')}`
        }
      ]
    };
  }

• src/converter.ts:335-340 (helper)

  Core helper method that returns the object containing arrays of supported input and output image formats.

  getSupportedFormats() {
    return {
      input: this.supportedInputFormats,
      output: this.supportedOutputFormats
    };
  }

• src/converter.ts:58-66 (helper)

  Class properties defining the lists of supported input and output image formats used by getSupportedFormats().

  private supportedInputFormats = [
    'jpg', 'jpeg', 'png', 'gif', 'bmp', 'tiff', 'tif', 
    'webp', 'svg', 'ico', 'psd', 'heic', 'heif', 'avif'
  ];
  
  private supportedOutputFormats = [
    'jpg', 'jpeg', 'png', 'gif', 'bmp', 'tiff', 'webp', 
    'svg', 'ico', 'avif'
  ];

• src/index.ts:191-197 (registration)

  Tool registration in the ListTools response, including name, description, and empty input schema (no parameters required).

    name: 'list_supported_formats',
    description: '列出支持的图片格式',
    inputSchema: {
      type: 'object',
      properties: {}
    }
  }

• src/index.ts:193-196 (schema)

  Input schema definition for the tool: an empty object since no parameters are needed.

  inputSchema: {
    type: 'object',
    properties: {}
  }
