indexnow-mcp

Submit URLs to search engines instantly from any AI agent.

An MCP server for the IndexNow protocol. Connect it to Claude Code, Claude Desktop, Cursor or any MCP-aware client, and your AI agent can push new or updated URLs to Bing, Yandex, Seznam and Naver the moment content changes — no waiting for a recrawl, no dashboard clicking.

Ship a blog post, ask your agent to submit it, get crawled within minutes.

Why

• Search engines take days or weeks to recrawl small sites. IndexNow flips that: you tell them.
• Agents already publish and edit content. Indexing should be part of the same automated loop.
• Zero dependencies beyond the MCP SDK. No accounts, no API keys from search engines — IndexNow is free and open.

Tools

Tool	What it does
generate_key()	Creates a fresh 32-char IndexNow key + setup instructions
verify_key(host, key)	Confirms your key file is reachable at https://host/<key>.txt
submit_urls(host, key, urls)	Submits up to 10,000 URLs to all IndexNow engines in one call
submit_sitemap(host, key, sitemap_url)	Fetches a sitemap.xml and submits every URL in it

Quick start

pip install mcp
git clone https://github.com/cyber-kani/indexnow-mcp

Claude Code:

claude mcp add indexnow -- python3 /path/to/indexnow-mcp/server.py

Claude Desktop / Cursor (mcpServers config):

{
  "mcpServers": {
    "indexnow": {
      "command": "python3",
      "args": ["/path/to/indexnow-mcp/server.py"]
    }
  }
}

Then just talk to your agent:

"Generate an IndexNow key for example.com" → host the key file it gives you

"Submit https://example.com/blog/new-post to search engines"

"Submit everything in https://example.com/sitemap.xml"

One-time site setup

1. generate_key() → you get e.g. 8d7e...bf5c
2. Put a file at https://your-site.com/8d7e...bf5c.txt containing exactly that key
3. verify_key("your-site.com", "8d7e...bf5c") → ok: true
4. Submit away. The key stays valid forever.

FAQ

Does Google support IndexNow? No — Google uses its own systems. IndexNow covers Bing, Yandex, Seznam and Naver, and Bing shares the signal with partners. For Google, keep your sitemap fresh in Search Console.

Rate limits? IndexNow accepts up to 10,000 URLs per request. Submit when content actually changes; spamming unchanged URLs can get a key ignored.

Is this safe to expose to an agent? The server can only announce URLs on hosts where you control the key file. It cannot modify your site or submit URLs for domains you don't own.
