Quickstart - LightOn Developers

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.

Bearer token
Query parameter

Pass the key in the Authorization header. Recommended for clients that support custom headers.

Authorization: Bearer $LIGHTON_API_KEY

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
