docx_to_html

Instructions

Implementation Reference

• src/tools/docxTools.ts:59-98 (handler)

  The docxToHtml async function that handles the actual DOCX-to-HTML conversion using the 'mammoth' library. It reads the DOCX file, converts it to HTML, and saves it to the output directory with a unique ID.

  export async function docxToHtml(inputPath: string, outputDir: string) {
    try {
      console.error(`Starting DOCX to HTML conversion...`);
      console.error(`Input file: ${inputPath}`);
      console.error(`Output directory: ${outputDir}`);
  
      // 確保輸出目錄存在
      try {
        await fs.access(outputDir);
        console.error(`Output directory exists: ${outputDir}`);
      } catch {
        console.error(`Creating output directory: ${outputDir}`);
        await fs.mkdir(outputDir, { recursive: true });
        console.error(`Created output directory: ${outputDir}`);
      }
  
      const uniqueId = generateUniqueId();
      const buffer = await fs.readFile(inputPath);
  
      const result = await mammoth.convertToHtml({ buffer });
      console.error(
        `Conversion completed with ${result.messages.length} messages`
      );
  
      const outputPath = path.join(outputDir, `converted_${uniqueId}.html`);
      await fs.writeFile(outputPath, result.value);
      console.error(`Written HTML to ${outputPath}`);
  
      return {
        success: true,
        data: `Successfully converted DOCX to HTML: ${outputPath}`,
      };
    } catch (error) {
      console.error(`Error in docxToHtml:`, error);
      return {
        success: false,
        error: error instanceof Error ? error.message : "Unknown error",
      };
    }
  }

• src/tools/docxTools.ts:15-32 (schema)

  The DOCX_TO_HTML_TOOL constant defines the tool's name ('docx_to_html'), description, and input schema specifying required inputPath and outputDir string parameters.

  export const DOCX_TO_HTML_TOOL: Tool = {
    name: "docx_to_html",
    description: "Convert DOCX to HTML while preserving formatting",
    inputSchema: {
      type: "object",
      properties: {
        inputPath: {
          type: "string",
          description: "Path to the input DOCX file",
        },
        outputDir: {
          type: "string",
          description: "Directory where HTML should be saved",
        },
      },
      required: ["inputPath", "outputDir"],
    },
  };

• src/tools/_index.ts:9-9 (registration)

  The tool is registered in the 'tools' array exported from _index.ts, making it available to the MCP server.

  export const tools = [DOCUMENT_READER_TOOL, PDF_MERGE_TOOL, PDF_SPLIT_TOOL, DOCX_TO_PDF_TOOL, DOCX_TO_HTML_TOOL, HTML_CLEAN_TOOL, HTML_TO_TEXT_TOOL, HTML_TO_MARKDOWN_TOOL, HTML_EXTRACT_RESOURCES_TOOL, HTML_FORMAT_TOOL, TEXT_DIFF_TOOL, TEXT_SPLIT_TOOL, TEXT_FORMAT_TOOL, TEXT_ENCODING_CONVERT_TOOL, EXCEL_READ_TOOL, FORMAT_CONVERTER_TOOL];

• src/index.ts:132-148 (handler)

  The call handler in the MCP server that routes 'docx_to_html' requests to the docxToHtml function and returns the result.

  if (name === "docx_to_html") {
    const { inputPath, outputDir } = args as {
      inputPath: string;
      outputDir: string;
    };
    const result = await docxToHtml(inputPath, outputDir);
    if (!result.success) {
      return {
        content: [{ type: "text", text: `Error: ${result.error}` }],
        isError: true,
      };
    }
    return {
      content: [{ type: "text", text: fileOperationResponse(result.data) }],
      isError: false,
    };
  }

• src/tools/docxTools.ts:10-12 (helper)

  Helper function generateUniqueId used to create unique filenames for the converted HTML output.

  function generateUniqueId(): string {
    return randomBytes(9).toString("hex");
  }
