Implementation Reference
- index.ts:256-289 (handler)The handler logic for executing the 'generate_pdf_from_text' tool. It uses PDFKit to generate a PDF from text content, applies formatting options, validates and saves to the output path, and returns a success message.
case "generate_pdf_from_text": { const { text_content, output_filename, output_dir = DEFAULT_OUTPUT_DIR, options = {} } = args as any; const outputPath = validateOutputPath(path.join(output_dir, output_filename)); await fs.mkdir(path.dirname(outputPath), { recursive: true }); const doc = new PDFDocument({ margins: options.margins || { top: 50, left: 50, right: 50, bottom: 50 } }); const stream = createWriteStream(outputPath); doc.pipe(stream); doc.font(options.font || 'Helvetica') .fontSize(options.fontSize || 12); doc.text(text_content); doc.end(); return new Promise((resolve) => { stream.on('finish', () => { resolve({ content: [ { type: "text", text: `PDF successfully generated from text: ${outputPath}` } ] }); }); }); } - index.ts:95-134 (schema)The tool definition including name, description, and detailed inputSchema with properties, defaults, and required fields for the generate_pdf_from_text tool.
{ name: "generate_pdf_from_text", description: "Generate a PDF from plain text using PDFKit", inputSchema: { type: "object", properties: { text_content: { type: "string", description: "Text content to convert to PDF" }, output_filename: { type: "string", description: "Name of the output PDF file (without path)" }, output_dir: { type: "string", description: "Output directory (optional, defaults to Downloads)", default: DEFAULT_OUTPUT_DIR }, options: { type: "object", description: "PDF formatting options", properties: { fontSize: { type: "number", default: 12 }, font: { type: "string", default: "Helvetica" }, margins: { type: "object", properties: { top: { type: "number", default: 50 }, left: { type: "number", default: 50 }, right: { type: "number", default: 50 }, bottom: { type: "number", default: 50 } } } } } }, required: ["text_content", "output_filename"] } }, - index.ts:175-177 (registration)Registration of the ListToolsRequestSchema handler, which returns the list of available tools including 'generate_pdf_from_text'.
server.setRequestHandler(ListToolsRequestSchema, async () => { return { tools }; }); - index.ts:30-41 (helper)Helper function used by the tool handler to validate that the output path is within allowed user directories for security.
function validateOutputPath(outputPath: string): string { const resolvedPath = path.resolve(outputPath); const isAllowed = ALLOWED_DIRS.some(allowedDir => resolvedPath.startsWith(path.resolve(allowedDir)) ); if (!isAllowed) { throw new Error(`Output path must be within allowed directories: ${ALLOWED_DIRS.join(", ")}`); } return resolvedPath; }
