# API reference

> MCP tools for publishing and retrieving Unfurl documents from Claude, Cursor, and other MCP clients.

# API reference

Unfurl exposes **four MCP tools** on the remote server. Your AI client calls them the same way it calls any other MCP tool — no REST boilerplate in the chat.

<Info>
  **Endpoint:** `https://mcp.unfurl.pub/mcp` — add this URL in Claude or Cursor. Follow **Before you start** to generate an API key and complete OAuth on the Unfurl authorize page.

## REST API

The same operations are available over HTTP if you prefer scripts or custom integrations. See [REST API (v1)](/api-reference/rest-api).

## Before you start

1. **Unfurl account** — Sign in at [unfurl.pub](https://unfurl.pub).
2. **API key** — Open **[Dashboard → API keys](https://unfurl.pub/dashboard/api-keys)**. Create a key with a label (e.g. `MCP`), then **copy the full `oodoc_…` secret** — it is displayed only once. You will paste it on the Unfurl authorize page when your AI client connects to MCP.
3. **MCP connection** — Add the endpoint `https://mcp.unfurl.pub/mcp` in Claude or Cursor and complete OAuth in the browser.
