# MCP server

> Connect AI tools like Claude Desktop and Cursor to the Inbox API

The Inbox MCP server gives AI tools direct access to the full [REST API](/api-reference/introduction) — threads, messages, prospects, tags, and more.

## Authentication

The MCP server uses the same API token as the REST API. Pass it in the `Authorization` header.

<Note>
  Need an API token? See [Authentication](/configuration/authentication).

## Server URL

```
https://mcp.inboxapp.com/mcp
```

## Client setup

### Claude Desktop

Add to your config file:

* **macOS:** `~/Library/Application Support/Claude/claude_desktop_config.json`
* **Windows:** `%APPDATA%\Claude\claude_desktop_config.json`

```json claude_desktop_config.json theme={null}
{
  "mcpServers": {
    "inbox": {
      "url": "https://mcp.inboxapp.com/mcp",
      "headers": {
        "Authorization": "Bearer <INBOX_API_TOKEN>"
      }
    }
  }
}
```

### Cursor

Add to `.cursor/mcp.json` in your project root:

```json .cursor/mcp.json theme={null}
{
  "mcpServers": {
    "inbox": {
      "url": "https://mcp.inboxapp.com/mcp",
      "headers": {
        "Authorization": "Bearer <INBOX_API_TOKEN>"
      }
    }
  }
}
```

Replace `<INBOX_API_TOKEN>` with your API token.
