docx_to_pdf

Instructions

Implementation Reference

• src/tools/docxTools.ts:112-137 (handler)

  The main handler function that converts DOCX to PDF using libreoffice-convert. Reads the DOCX file, converts it via LibreOffice, and writes the PDF output.

  export async function convertDocxToPdf(inputPath: string, outputPath: string) {
    try {
      const ext = path.extname(inputPath).toLowerCase();
      if (ext !== ".docx") {
        throw new Error("Input file must be a .docx file");
      }
  
      if (path.extname(outputPath).toLowerCase() !== ".pdf") {
        throw new Error("Output file must have .pdf extension");
      }
  
      const docxBuffer = await fs.readFile(inputPath);
      const pdfBuffer = await convertAsyncPromise(docxBuffer, ".pdf", undefined);
      await fs.writeFile(outputPath, pdfBuffer);
  
      return {
        success: true,
        data: `Successfully converted ${inputPath} to ${outputPath}`,
      };
    } catch (error) {
      return {
        success: false,
        error: error instanceof Error ? error.message : "Unknown error",
      };
    }
  }

• src/tools/docxTools.ts:35-56 (schema)

  Tool definition with name 'docx_to_pdf', description, and inputSchema requiring inputPath and outputPath strings.

  export const DOCX_TO_PDF_TOOL: Tool = {
    name: "docx_to_pdf",
    description: "Convert DOCX files to PDF format",
    inputSchema: {
      type: "object",
      properties: {
        inputPath: {
          type: "string",
          description: "Path to the input DOCX file",
        },
        outputPath: {
          type: "string",
          description: "Path where the output PDF file should be saved",
        },
      },
      required: ["inputPath", "outputPath"],
    },
  };
  export interface DocxToPdfArgs {
    inputPath: string;
    outputPath: string;
  }

• src/tools/docxTools.ts:53-56 (schema)

  TypeScript interface DocxToPdfArgs defining inputPath and outputPath fields.

  export interface DocxToPdfArgs {
    inputPath: string;
    outputPath: string;
  }

• src/tools/docxTools.ts:101-110 (helper)

  Type guard function isDocxToPdfArgs that validates runtime arguments for the docx_to_pdf tool.

  export function isDocxToPdfArgs(args: unknown): args is DocxToPdfArgs {
    return (
      typeof args === "object" &&
      args !== null &&
      "inputPath" in args &&
      "outputPath" in args &&
      typeof (args as DocxToPdfArgs).inputPath === "string" &&
      typeof (args as DocxToPdfArgs).outputPath === "string"
    );
  }

• src/index.ts:77-82 (registration)

  Server-side handler registration that dispatches 'docx_to_pdf' tool calls to the convertDocxToPdf function.

  if (name === "docx_to_pdf") {
    if (!isDocxToPdfArgs(args)) {
      throw new Error("Invalid arguments for docx_to_pdf");
    }
  
    const result = await convertDocxToPdf(args.inputPath, args.outputPath);
