# MCP

The **MCP** settings page lets external AI applications connect to your documentation through a hosted Model Context Protocol (MCP) server. Every Doccupine site exposes an MCP endpoint at `/api/mcp` that AI tools can query to search and read your content.

## Connect your site with AI apps

The **Connect your site with AI apps** card gives you a ready-to-paste MCP configuration for popular AI tools. Pick a tab, copy the snippet, and add it to that tool's MCP config:

- **Claude** - add the configuration to Claude Desktop's `claude_desktop_config.json`, or add the server URL as a connector from Claude's settings.
- **Cursor** - add the configuration to Cursor's `~/.cursor/mcp.json`, or connect it from Cursor's MCP settings.
- **Others** - a generic `mcpServers` block for any MCP-compatible application.

Every snippet points to your site's own MCP endpoint, for example:

```json
{
  "mcpServers": {
    "Your Project": { "url": "https://your-site.com/api/mcp" }
  }
}
```

<Callout type="note">
  The connection snippet appears once your site has been deployed. If you haven't published yet, deploy your site first to get its MCP server URL.

## MCP server authentication

On a public site, the MCP endpoint is publicly accessible by default. When the site is [password protected](/platform/authentication), MCP requires the same session unless you configure its dedicated API key:

1. Enable **Require API key for MCP access**.
2. Enter an API key.
3. Save.

Once enabled, clients must include the key as a Bearer token in the `Authorization` header of every request to `/api/mcp`.

<Callout type="warning">
  The API key is stored as an environment variable (`DOCS_API_KEY`) on your deployment, not in a JSON file. After saving, a redeploy is triggered automatically to apply the change.
