Implementation Reference
- src/server.ts:48-71 (handler)Switch case handler for 'youtube-to-markdown' tool (shared with other URL-based tools). Validates URL, checks protocol and private IP, then delegates to Markdownify.toMarkdown for conversion.switch (name) { case tools.YouTubeToMarkdownTool.name: case tools.BingSearchResultToMarkdownTool.name: case tools.WebpageToMarkdownTool.name: if (!validatedArgs.url) { throw new Error("URL is required for this tool"); } const parsedUrl = new URL(validatedArgs.url); if (!["http:", "https:"].includes(parsedUrl.protocol)) { throw new Error("Only http: and https: schemes are allowed."); } if (is_ip_private(parsedUrl.hostname)) { throw new Error(`Fetching ${validatedArgs.url} is potentially dangerous, aborting.`); } result = await Markdownify.toMarkdown({ url: validatedArgs.url, projectRoot: validatedArgs.projectRoot, uvPath: validatedArgs.uvPath || process.env.UV_PATH, }); break;
- src/tools.ts:3-17 (schema)Tool schema defining name, description, and input schema (requires 'url') for youtube-to-markdown.export const YouTubeToMarkdownTool = ToolSchema.parse({ name: "youtube-to-markdown", description: "Convert a YouTube video to markdown, including transcript if available", inputSchema: { type: "object", properties: { url: { type: "string", description: "URL of the YouTube video", }, }, required: ["url"], }, });
- src/server.ts:33-37 (registration)Registration of all tools (including youtube-to-markdown) via ListToolsRequestSchema handler, exporting Object.values(tools).server.setRequestHandler(ListToolsRequestSchema, async () => { return { tools: Object.values(tools), }; });
- src/Markdownify.ts:74-124 (helper)Core helper method that fetches URL (for youtube-to-markdown), saves to temp file, executes 'markitdown' via 'uv run', and returns markdown result.static async toMarkdown({ filePath, url, projectRoot = path.resolve(__dirname, ".."), uvPath = "~/.local/bin/uv", }: { filePath?: string; url?: string; projectRoot?: string; uvPath?: string; }): Promise<MarkdownResult> { try { let inputPath: string; let isTemporary = false; if (url) { const response = await fetch(url); let extension = null; if (url.endsWith(".pdf")) { extension = "pdf"; } const arrayBuffer = await response.arrayBuffer(); const content = Buffer.from(arrayBuffer); inputPath = await this.saveToTempFile(content, extension); isTemporary = true; } else if (filePath) { inputPath = filePath; } else { throw new Error("Either filePath or url must be provided"); } const text = await this._markitdown(inputPath, projectRoot, uvPath); const outputPath = await this.saveToTempFile(text); if (isTemporary) { fs.unlinkSync(inputPath); } return { path: outputPath, text }; } catch (e: unknown) { if (e instanceof Error) { throw new Error(`Error processing to Markdown: ${e.message}`); } else { throw new Error("Error processing to Markdown: Unknown error occurred"); } } }
