Let AI handle file transfers with the file.kiwi MCP Server

MCP Server for file.kiwi has been released. Now, if you just say “Share this file” to an AI tool like Claude or Cursor, the AI ​​will upload it directly and even provide a download link.

What is MCP Server?

Model Context Protocol (MCP) is a standard created by Anthropic and is a connection method that allows AI to directly use external tools or services.

To put it simply, it is giving a “hand” to an AI assistant. Originally, AI could only talk, but through MCP, it can directly perform actual tasks such as reading files, searching, or accessing services.

When you install file.kiwi MCP Server, AI automatically uploads the specified file to file.kiwi and creates a sharing link.

Differences from other file sharing methods

Typical file sharing MCP servers provide a download link only when the upload is completely completed. If the file is several GB in size, you may have to wait a while.

file.kiwi MCP Server is different.

The moment you start entering files, a download link will be created immediately. Recipients can start downloading right away even while the upload is in progress. The larger the file, the bigger the difference.

  • No need to wait for upload completion
  • AI can deliver links directly
  • Recipients can also start downloading immediately

Installation method

1. Find the MCP settings JSON file

Open the MCP settings for the AI service you use and locate its JSON configuration file.

  • Claude Desktop — Add directly to the claude_desktop_config.json file
  • Cursor — Add it from Settings > MCP or edit ~/.cursor/mcp.json
  • windsurf — Add from Cascade panel > MCP icon or edit file ~/.codeium/windsurf/mcp_config.json
  • Cline — Add it in the VS Code extension settings or edit cline_mcp_settings.json
  • Claude Code — In terminal type: claude mcp add filekiwi -- npx -y @file-kiwi/filekiwi-mcp-server

2. Edit the MCP settings JSON file

Just add the code below to your MCP configuration file and you're ready to go. No separate installation or API key required.

{
  "mcpServers": {
    "filekiwi": {
      "command": "npx",
      "args": ["-y", "@file-kiwi/filekiwi-mcp-server"]
    }
  }
}

For Claude Desktop, add it to claude_desktop_config.json. For Cursor, add it on the MCP settings screen.

3. When file access is blocked

In some environments (e.g. Claude Desktop), local file system access is restricted by default. In this case, the AI ​​may not be able to read the file paths on your computer. To fix this, add filesystem MCP server together.

{
  "mcpServers": {
    "filekiwi": {
      "command": "npx",
      "args": ["-y", "@file-kiwi/filekiwi-mcp-server"]
    },
    "filesystem": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-filesystem", "C:/Users/username"]
    }
  }
}

Change C:/Users/username to the folder path that AI will allow access to.

Example usage

Once the MCP server is connected, all you have to do is make a request to the AI in natural language.

  • "Share this file: C:\Users\me\report.pdf"
  • "Upload /home/user/photo.png to file.kiwi"
  • "Create a download link for presentation.pptx"

AI automatically uploads and returns the sharing link below.

https://file.kiwi/abcdef12#hashashahshashhashhash

Anyone who receives the link can download it right away without registering.

  • Can be used with just a web browser
  • Uploaded files are encrypted (E2E, 128-bit AES-GCM) and stored.
