  async function performGetSubtitle(tiktok_url: string, language_code: string) { const url = new URL('https://tikneuron.com/api/mcp/get-subtitles'); url.searchParams.set('tiktok_url', tiktok_url); if (language_code){ url.searchParams.set('language_code', language_code); } const response = await fetch(url, { headers: { 'Accept': 'application/json', 'Accept-Encoding': 'gzip', 'MCP-API-KEY': TIKNEURON_MCP_API_KEY, } }); if (!response.ok) { throw new Error(`TikNeuron API error: ${response.status} ${response.statusText}\n${await response.text()}`); } const data = await response.json() as Subtitle; return data.subtitle_content || 'No subtitle available'; }
• index.ts:331-342 (handler)

  Tool dispatch handler in CallToolRequestSchema: validates arguments using isGetSubtitleArgs and calls performGetSubtitle.
  case "tiktok_get_subtitle": { if (!isGetSubtitleArgs(args)) { throw new Error("Invalid arguments for tiktok_get_subtitle"); } const { tiktok_url, language_code } = args; const results = await performGetSubtitle(tiktok_url, language_code); return { content: [{ type: "text", text: results }], isError: false, }; }
• index.ts:12-34 (schema)

  Tool schema definition: name, description, inputSchema with tiktok_url (required) and optional language_code.
  const GET_SUBTITLE: Tool = { name: "tiktok_get_subtitle", description: "Get the subtitle (content) for a TikTok video url." + "This is used for getting the subtitle, content or context for a TikTok video." + "Supports TikTok video url (or video ID) as input and optionally language code from the tool post details" + "Returns the subtitle for the video in the requested language and format." + "If no language code is provided, the tool will return the subtitle of automatic speech recognition.", inputSchema: { type: "object", properties: { tiktok_url: { type: "string", description: "TikTok video URL, e.g., https://www.tiktok.com/@username/video/1234567890 or https://vm.tiktok.com/1234567890, or just the video ID like 7409731702890827041", }, language_code: { type: "string", description: "Language code for the subtitle, e.g., en for English, es for Spanish, fr for French, etc.", }, }, required: ["tiktok_url"] } };

  Registration of tools list handler, including tiktok_get_subtitle (via GET_SUBTITLE).
  server.setRequestHandler(ListToolsRequestSchema, async () => ({ tools: [GET_SUBTITLE, GET_POST_DETAILS, SEARCH], }));
• index.ts:171-178 (helper)
