Quick start

1. Get a KALEI API key

kaleiai.com/get-started → sign up → Dashboard → API Keys

2. Configure your MCP client

Claude Code (~/.claude.json or settings):

{
  "mcpServers": {
    "kalei": {
      "command": "npx",
      "args": ["-y", "@kalei-labs/mcp-server"],
      "env": {
        "KALEI_API_KEY": "kalei_live_..."
      }
    }
  }
}

Cursor (.cursor/mcp.json):

{
  "mcpServers": {
    "kalei": {
      "command": "npx",
      "args": ["-y", "@kalei-labs/mcp-server"],
      "env": { "KALEI_API_KEY": "kalei_live_..." }
    }
  }
}

3. Use it

In Claude Code / Cursor chat:

Show me the KALEI leaderboard and compare Claude Sonnet vs GPT-5.

Profile gpt-4o for me using my OpenAI key sk-... — use standard depth.

Ask the Parliament: should AI systems have persistent memory?

The model will call the appropriate tools and return results.
