Implementation Reference

• src/index.ts:422-446 (handler)

  The tool `indexnow_list_engines` is defined and implemented within the `server.tool` call, handling the request by iterating over `INDEXNOW_ENDPOINTS` and providing a formatted text response.

  server.tool(
    "indexnow_list_engines",
    "List all supported IndexNow search engines and their API endpoints.",
    {},
    async () => {
      let output = `## Supported IndexNow Engines\n\n`;
      output += `| Engine | Endpoint |\n|--------|----------|\n`;
      for (const [name, url] of Object.entries(INDEXNOW_ENDPOINTS)) {
        output += `| ${name} | ${url} |\n`;
      }
  
      output += `\n### Google Indexing API\n`;
      output += `| Service | Endpoint |\n|---------|----------|\n`;
      output += `| Google Indexing API | ${GOOGLE_INDEXING_API_URL} |\n`;
      output += `| Google Batch API | ${GOOGLE_BATCH_URL} |\n`;
  
      output += `\n### Notes\n`;
      output += `- **IndexNow** is supported by Bing, Yandex, Naver, and Seznam\n`;
      output += `- **Google** has its own Indexing API (requires service account + OAuth2)\n`;
      output += `- IndexNow submissions are free and unlimited\n`;
      output += `- Google Indexing API has a daily quota (200 URLs/day by default)\n`;
  
      return { content: [{ type: "text" as const, text: output }] };
    }
  );
