Aktar for Cline

Upload files to your own bucket from Cline

Add Aktar to Cline and it can upload screenshots and files to your own S3, Cloudflare R2 or Backblaze B2 bucket, choose the right destination and find what you uploaded before. It runs next to the Aktar app on your computer, so your storage keys never leave Aktar.

Set it upgetaktar/cliv0.6.0

Upload screenshots/bug-412.png and add it to the issue text.

Called Aktarupload_file{ "path": "screenshots/bug-412.png" }

Uploaded. Here's the Markdown for the issue:

https://files.example.com/2026/11/bug-412.png

What you can ask

  • Screenshots for an issue

    “Upload the screenshots in screenshots/ and write the issue with them.”

    Cline uploads each image and writes the Markdown. Aktar converts and cleans images as the destination says.

    Tools: upload_file

  • Choose a destination

    “Upload the release zip to my Builds destination.”

    It lists your Aktar destinations and uploads to the one you name. Otherwise Aktar picks one by file type.

    Tools: list_destinations, upload_file

  • Find an image

    “Find the dashboard screenshot I uploaded this month.”

    It searches Aktar's history by name and date, and can look at thumbnails to tell images apart.

    Tools: get_thumbnail, search_uploads

Set it up

  1. Install Aktar for Mac or Windows and add a destination (your bucket). In Aktar, open Settings > Integrations, turn on Allow local connections and copy the token, then paste it into this command. It needs Node.js 18 or later.

    npx @getaktar/cli login

  2. In Cline, open the MCP Servers view and choose Configure MCP Servers. Add Aktar to the file that opens, with the folder your work is in after --root.

    In cline_mcp_settings.json
    {
  "mcpServers": {
    "aktar": {
      "command": "npx",
      "args": ["-y", "@getaktar/cli", "mcp", "--root", "/Users/you/Projects"]
    }
  }
}

  3. Save the file. Cline starts the server, and aktar appears in the list of installed servers with its tools.

You can also ask Cline to do it: “Set up the MCP server from https://github.com/getaktar/cli”. It reads the setup steps there and writes this file for you.

Replace /Users/you/Projects with your own folder (on Windows, like C:\\Users\\you\\Projects), and repeat --root and a folder to allow more. Because folders are given with --root, uploading straight from the clipboard is left out. Add --allow-replace or --allow-delete to the arguments to let Cline replace or delete uploads.

What it can touch

Files come only from the folders the server may use, and secrets such as SSH keys, .env files and cloud credentials are never uploaded. Replacing and deleting uploads are off unless you turn them on. Your storage keys stay in Aktar: the agent gets file names and links back, and nothing goes to us. An upload is public to anyone with its link, so ask only for what you want to share.

Details are in the privacy policy. Every tool and option is on the MCP server page.

Questions

Does Cline get my storage keys?

No. Your keys stay in the Aktar app. The server only uses the local token that npx @getaktar/cli login saves in a file only you can read, and it talks to Aktar on 127.0.0.1.

Does Cline ask before uploading?

Yes, unless you've turned on auto-approve for that tool. Searching and listing only look; uploading changes your bucket.

Which bucket does it upload to?

The same as a drop on Aktar's menu bar: the destination whose Use For matches the file type, or the selected one. Name a destination in your request and Cline uses that one.

Does it work on Windows?

Yes, with Aktar for Windows 0.11.0 or later. On a Mac you need Aktar for Mac 0.18.0 or later.
