MCP server

SEO data inside Claude, ChatGPT and any MCP client

SearcherLite is a remote MCP server (Model Context Protocol) with 27 tools for Google keyword, domain, backlink and AI-visibility data. Connect it once and ask in plain language. The assistant picks the right lookups, combines the results and writes the summary. Every call is paid in credits from your SearcherLite balance, and there is no subscription.

Spending safety

Built so a session cannot run away with your credits

  • Every tool description states its cost, and every answer ends with what it cost, what you have used today and your balance.
  • Calls of 10 credits or more return a price first and only run when you confirm.
  • A daily spending cap you set yourself (default 200 credits, up to 5000), so an automated session can never run away with your credits.
  • At most 20 calls per minute, and credits are deducted atomically on the server.

Connect

Set it up in your client

Claude and ChatGPT need no installation and no keys: paste the address, log in with your SearcherLite account and click Allow. Other clients use a SearcherLite API key, created under MCP in your profile.

Claude (claude.ai, desktop app, Cowork and Claude Code)

One setup covers chat and Cowork in the desktop app and on claude.ai, and Claude Code in the terminal, in VS Code and in the desktop app's Code tab, as long as Claude Code is logged in with the same claude.ai account.

  1. In the Claude desktop app or Cowork, open Customize; on claude.ai, open Settings and then Connectors. Choose Add custom connector.
  2. Name it SearcherLite and paste this address:
    https://searcherlite.com/api/mcp
  3. Leave everything else as Claude detects it (authentication Always required, OAuth client register one automatically, no extra headers) and click Add.
  4. A SearcherLite login page opens. Log in, or sign up if you are new, and click Allow. Done.
ChatGPT
  1. In ChatGPT, open Settings and then Connectors, and create a custom connector (ChatGPT calls this Developer mode).
  2. Paste the same address:
    https://searcherlite.com/api/mcp
  3. Log in with your SearcherLite account when asked and click Allow.
Claude Code without a claude.ai login

If Claude Code is logged in with your claude.ai account, the connector from the Claude section already works there. Otherwise (for example when Claude Code runs on an API key), register the server yourself. This applies to the terminal, the VS Code extension and the desktop app's Code tab alike, since they share one configuration. Run this and log in in the browser window that opens:

claude mcp add --transport http searcherlite https://searcherlite.com/api/mcp

Or use a SearcherLite API key instead of the browser login:

claude mcp add --transport http searcherlite https://searcherlite.com/api/mcp --header "Authorization: Bearer sl_YOUR_API_KEY"
Cursor and other MCP clients

Add this to the client's MCP configuration with a SearcherLite API key:

{
  "mcpServers": {
    "searcherlite": {
      "url": "https://searcherlite.com/api/mcp",
      "headers": {
        "Authorization": "Bearer sl_YOUR_API_KEY"
      }
    }
  }
}
Gemini CLI

Add this to ~/.gemini/settings.json with a SearcherLite API key:

{
  "mcpServers": {
    "searcherlite": {
      "httpUrl": "https://searcherlite.com/api/mcp",
      "headers": {
        "Authorization": "Bearer sl_YOUR_API_KEY"
      }
    }
  }
}

Any client that supports remote MCP servers over HTTP works: use the address with OAuth login, or an API key in the Authorization header. The server publishes OAuth metadata at /.well-known/oauth-protected-resource, so clients discover the login flow on their own.

FAQ

Questions

Do I need a SearcherLite account?

Yes. Sign up with an email address and you get 20 free credits, no credit card. When you add the server to Claude or ChatGPT, a SearcherLite login page opens; log in (or sign up there) and click Allow.

What does it cost?

Every tool is paid in SearcherLite credits from the same balance as the web app, most lookups cost 1 to 4 credits, and there is no subscription. The cost of every tool is stated in its description, and each answer ends with what it cost, what you have used today and your balance.

Can an AI session run away with my credits?

No. Calls of 10 credits or more return a price first and only run when you confirm. A daily spending cap (default 200 credits, up to 5000) stops everything else, and the server allows at most 20 calls per minute. Credits are deducted atomically, so parallel calls cannot overdraw a balance.

Which clients are supported?

Any client that supports remote MCP servers over Streamable HTTP. Claude (claude.ai, the desktop app, Cowork and Claude Code) and ChatGPT connect with browser login (OAuth 2.1). Cursor, Gemini CLI, scripts and other clients connect with a SearcherLite API key in the Authorization header.

Is there a REST API as well?

No. The MCP server is the programmatic interface, and API keys exist for MCP clients only.

Where does the data come from?

From DataForSEO: Google Ads data, live Google results, a backlink index and an index of AI answers. Results from MCP calls are also saved to History in the web app.
