# Quickstart

> Connect to the LightOn MCP server.

LightOn exposes a hosted MCP server that lets MCP-compatible clients (Claude Desktop, Claude Code, Cursor, etc.) search and ingest documents in your workspaces.

## Server URL

```
https://api.lighton.ai/mcp
```

## Authentication

The server accepts an API key in two forms. Pick whichever fits your client.

<Tabs>
  <Tab title="Bearer token">
    Pass the key in the `Authorization` header. Recommended for clients that support custom headers.

    ```
    Authorization: Bearer $LIGHTON_API_KEY
    ```
  </Tab>

  <Tab title="Query parameter">
    Append `?apiKey=$LIGHTON_API_KEY` to the server URL. Useful when the client only accepts a plain URL and no headers.

    ```
    https://api.lighton.ai/mcp?apiKey=$LIGHTON_API_KEY
    ```
