Prerequisites

​
Configuration

Cursor configures MCP servers via a JSON file. Add the following to ~/.cursor/mcp.json: 
{
  "mcpServers": {
    "lighton": {
      "url": "https://api.lighton.ai/mcp",
      "headers": {
        "Authorization": "Bearer ${env:CONSOLE_API_KEY}"
      }
    }
  }
}
${env:CONSOLE_API_KEY} is Cursor’s syntax for reading an environment variable at runtime. The key is never stored in the config file. Make sure CONSOLE_API_KEY is set in your shell environment, you can grab your key from the LightOn Console. To scope the server to a single project instead, place the same snippet in .cursor/mcp.json at the root of your project.

​
Verification

  1. Open Settings → Features → Model Context Protocol and confirm lighton appears in the list.
  2. Check the connection logs via Output panel (Cmd+Shift+U) and select MCP Logs from the dropdown.
  3. Test the connection with a prompt like: 
    Search my LightOn workspaces for documents about [topic]
You’re all set. From any Cursor session you can now ask it to search or ingest documents in your LightOn workspaces directly.
