MCP server for [SwissTransfer](https://www.swisstransfer.com) file sharing. Upload files up to 50 GB, get shareable download links, check transfer status — all from Claude Code, Cursor, or any MCP client.

## Features

- **Upload files** — Send any file via SwissTransfer and get a download link
- **Transfer info** — Check status, files, and expiration of existing transfers

## Setup

### 1. Get an Infomaniak API Token

1. Go to [Infomaniak Token Manager](https://manager.infomaniak.com/v3/ng/profile/user/token/list)
2. Create a new API token (free Infomaniak account required)
3. Copy the token — it's shown only once

### 2. Install

#### Claude Code

```bash
claude mcp add swisstransfer -- npx swisstransfer-mcp
```

Then set the token in your environment:

```bash
export SWISSTRANSFER_TOKEN=your_token_here
```

Or add it to your Claude Code MCP config:

      }
    }
  }
}
```

#### From source

```bash
git clone https://github.com/altovate/swisstransfer-mcp.git
cd swisstransfer-mcp
npm install
npm run build
```

Then add to your MCP config:

```json
