Aktar

[Aktar]

Aktar CLI

Upload files to your own S3, Cloudflare R2 or Backblaze B2 bucket from the terminal, and get the link.

[npm version] [CI] [MIT license]

[aktar upload in a terminal: links, Markdown and JSON output]

The aktar command talks to the Aktar app on your Mac or Windows PC, so it uses the destinations, keys, path templates and link settings you already set up there. Your storage keys never leave the app.

Install

npm install -g @getaktar/cli# orbrew install getaktar/tap/aktar-cli

Or run it without installing: npx @getaktar/cli upload file.png.

Requires Node.js 18 or later and Aktar for Mac 0.4.0 or later, or Aktar for Windows.

Connect to Aktar

1. In Aktar, open Settings > Integrations and turn on Allow local connections.
2. Copy the token shown there.
3. Run:

aktar login

and paste the token when asked. It's checked against Aktar and saved to ~/.config/aktar/cli.json (%APPDATA%\aktar\cli.json on Windows), readable only by you. You can also pipe it in (pbpaste | aktar login) or set AKTAR_TOKEN (and AKTAR_PORT if you changed the port) instead.

Without -d, files go to the destination selected in Aktar's menu bar. Uploads show up in Aktar's history like any other.

--format chooses what's printed: url (default), markdown, html, or custom (your template from Aktar). --expires takes 1, 7, 14 or 30 days and needs Aktar's auto-delete rules on that destination; without it, files are kept.

--name uploads a single file under another name: it's what {filename} and {ext} in the destination's path template become, and what Aktar's history shows. If the name has no extension, the file's own is added (--name cover uploads IMG_4021.jpg as cover.jpg); if it has one, it's used as given. With --folder, it's the name inside the folder.

If the same file (same contents, destination and expiry) is already in the bucket, Aktar doesn't upload it again and gives you the existing link. aktar prints the link as usual and notes it on stderr (aktar: photo.jpg: already uploaded, reused the existing link), so scripts reading stdout still get one link per file. This needs Aktar for Mac 0.10.0 or Windows 0.3.0.

QR codes

aktar upload --qr prints a QR code under each link, so you can open it on your phone. The QR code is always of the link itself, whatever --format prints. It's drawn black on white in the terminal, whatever its theme; when the output isn't a terminal, or NO_COLOR is set, it's drawn without colors (light modules as blocks), which phone cameras read on a light or dark background. --qr can't be combined with --json.

aktar qr <text> shows the QR code of any link or text; quote text with spaces. Given an upload ID from aktar history --json, it shows that upload's link and its QR code. --png <file> saves the QR code as a PNG instead:

aktar qr https://files.example.com/2026/09/7f3c2a91.png --png link.png

What Aktar does for you

The app does the work per destination, so the CLI needs nothing extra for it:

• Converting images to WebP or AVIF, if the destination is set to
• {md5} and {sha256} in path templates, to name files by their contents
• Big files: past 5 GB, Aktar uploads in parts and resumes after a dropped connection. aktar streams the file to the app, so its size doesn't matter

The link aktar prints is the one for the file as stored, after any conversion.

JSON output

aktar upload --json prints an array with one entry per uploaded file:

[  {    "id": "0B6C…",    "filename": "photo.jpg",    "objectKey": "2026/09/7f3c2a91.jpg",    "url": "https://files.example.com/2026/09/7f3c2a91.jpg",    "destinationId": "5D1A…",    "destinationName": "Screenshots",    "mimeType": "image/jpeg",    "size": 482113,    "createdAt": "2026-09-30T12:00:00Z",    "expiresAt": null,    "formats": { "url": "…", "markdown": "…", "html": "…", "custom": "…" },    "reused": false  }]

reused is true when nothing was uploaded because the file was already there; older versions of Aktar leave it out.

Exit codes

AI agents (MCP and skill)

MCP server

aktar mcp runs a Model Context Protocol server, so Claude, Cursor, VS Code, Codex and other agents can upload through Aktar, find past uploads and make links. Connect Aktar first (aktar login), then add it to your agent:

claude mcp add aktar -- aktar mcp            # Claude Codecodex mcp add aktar -- aktar mcp             # Codex

For Claude Desktop, Cursor, VS Code and others that take a JSON config:

{  "mcpServers": {    "aktar": { "command": "aktar", "args": ["mcp"] }  }}

Without a global install, use "command": "npx", "args": ["-y", "@getaktar/cli", "mcp"].

Uploading publishes a file, so keep an eye on what your agent sends. Your agent asks before calling a tool unless you allow it, and these options narrow what the server can do:

• --root <folder>: only upload files from this folder (repeat for more). Paths are resolved, symlinks included, before they're checked.
• --read-only: only the tools that change nothing (search, list, links, thumbnails).
• --allow-delete: also offer delete_upload, which is left out by default.

claude mcp add aktar -- aktar mcp --root ~/Projects --root ~/Desktop

The server speaks both the current per-request protocol (2026-07-28) and the earlier initialize versions (2024-11-05 to 2025-11-25).

Agent skill

Agents that use skills but not MCP can use the CLI directly. aktar skill prints a SKILL.md that teaches them how:

mkdir -p ~/.claude/skills/aktar && aktar skill > ~/.claude/skills/aktar/SKILL.md

Typora

In Typora, open Settings > Image > Image Upload, choose Custom Command and enter:

aktar upload

Typora passes the image paths and reads one link per line. Click Test Uploader to check it.
