How to Set Up and Use Kagi Search
Kagi Session2API MCP Server provides free access to Kagi's privacy-focused web search and URL summarizer through browser session tokens, bypassing the need for a paid Kagi API subscription. The server exposes two tools: kagi_search_fetch for full web search supporting advanced Kagi operators such as site filters, file type restrictions, language preferences, and date ranges, and kagi_summarizer for generating concise summaries of any URL with multiple engine options. Compatible with Claude Desktop, Cursor, Windsurf, Hermes, and any MCP-standard client.
Prerequisites
- Python 3.10 or later with uv or pip package manager installed
- An active Kagi account (free tier available at kagi.com)
- A Kagi session token from Settings → Account → Session Link on kagi.com
- An MCP-compatible client such as Claude Desktop, Cursor, or Windsurf
Install the package via pip or uvx
Install kagi-session2api-mcp from PyPI, or use uvx to run it without a permanent install.
pip install kagi-session2api-mcp
# or without installing:
uvx kagi-session2api-mcpRetrieve your Kagi session token
Log into kagi.com, go to Settings → Account → Session Link, and copy the token value from the URL. This token is used instead of a paid API key.
Configure environment variables
Set your session token. You can provide a single token or multiple comma-separated tokens for higher throughput. Optionally specify a config file path.
export KAGI_SESSION_TOKEN="your_session_token_here"
# For multiple tokens:
export KAGI_SESSION_TOKENS="token1,token2"Add the server to your MCP client configuration
Open claude_desktop_config.json and add the kagi-session2api-mcp server entry with the session token in the env block.

}Restart your MCP client and verify
Restart Claude Desktop or your chosen client. Test with a simple search query to confirm the server is connected and the session token is valid.

Requests fail with 401 or session token expired errors
Session tokens expire when your Kagi session ends. Return to kagi.com → Settings → Account → Session Link and copy a fresh token, then update KAGI_SESSION_TOKEN in your MCP config and restart the client.
Rate limit errors appear when making rapid searches
The server limits each token to 5 requests per second via a token bucket algorithm. Add multiple valid session tokens as a comma-separated list in KAGI_SESSION_TOKENS to spread load across tokens.
The kagi_summarizer tool returns an error for some URLs
Some URLs are blocked by paywalls or robots.txt restrictions that prevent the Kagi summarizer from accessing the content. Try a different summarizer engine by specifying the engine parameter, or use kagi_search_fetch to find a cached or alternative version of the content.
