Local image tools: circle crop, crop, resize, compress, convert JPG/PNG/WebP/AVIF. By RoundCut.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Design, images & audio

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • The registry lists no key to fill in.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "roundcut": {
      "command": "npx",
      "args": [
        "-y",
        "roundcut-mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add roundcut -- npx -y roundcut-mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "roundcut": {
      "command": "npx",
      "args": [
        "-y",
        "roundcut-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "roundcut": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "roundcut-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

What it can do

Common questions

Is Roundcut MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.2) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

roundcut-mcp

Local image tools for AI agents, as an MCP server. Circle crop, crop, resize, compress and convert JPG, PNG, WebP and AVIF on your own machine with sharp. No network calls, no accounts, no upload: the files never leave the disk.

Made by RoundCut, the free image tools site (29 languages).

Install

Node 20 or newer.

npx roundcut-mcp
Claude Desktop / Claude Code
{

"mcpServers": { "roundcut": { "command": "npx", "args": ["-y", "roundcut-mcp"] } } }

Claude Code: claude mcp add roundcut -- npx -y roundcut-mcp

Cursor, Windsurf, VS Code

Same shape: a stdio server, command npx, args -y roundcut-mcp.

Smithery

smithery.ai/servers/araluma/roundcut-mcp installs a self-contained bundle for macOS (Apple Silicon) and Windows (x64). On Linux or an Intel Mac, use npx above.

Tools

ToolWhat it doesAn agent calls it when
image_infoFormat, dimensions, alpha, EXIF orientation.the user asks what an image is, or before picking crop/resize numbers
circle_cropRound profile picture: centered square plus a circular transparent mask. size, format (png default), background for jpeg.the user wants a round avatar for Discord, Slack, LinkedIn, WhatsApp or GitHub
crop_imagePixel box (left, top, width, height) or a centered aspect such as 1:1, 4:5, 16:9.the user wants part of an image or a fixed ratio (square post, 4:5 portrait, 16:9 banner)
resize_imageBy width, height or percent. Keeps the aspect ratio, never enlarges unless enlarge: true. Lanczos3.the user gives target pixel dimensions
compress_imageSmaller file, same format. quality for jpg/webp/avif (mozjpeg for jpg), lossless recompression for png.the file must be lighter (upload limit, faster page) at the same size and format
convert_imageTo jpeg, png, webp or avif. Input may also be GIF, TIFF or HEIC. Transparency kept, or flattened onto background for jpeg.the user needs another file type, e.g. iPhone HEIC to JPG, PNG to WebP
roundcut_web_toolsLinks to the browser tools this server does not run locally: background remover, AI upscaler, batch convert, JPG to PDF.the user asks for one of those, instead of declining

Every tool takes an input path and writes next to it by default (photo.jpg becomes photo-circle.png, photo-resized.jpg, photo.webp), or to output. Results carry a text summary, a resource_link to the file, structured JSON (output, format, width, height, bytes, inputBytes) and a small JPEG preview (preview: false to skip it).

Example, from a chat client with the server attached:

Make ~/Pictures/me.jpg a 512 px round avatar as WebP.

calls circle_crop with { "input": "~/Pictures/me.jpg", "size": 512, "format": "webp" } and answers with the file path, the dimensions and the byte count.

Limits

  • Inputs above 80 megapixels are refused, so a stray call cannot allocate gigabytes.
  • EXIF orientation is applied on read; the output is upright and carries no EXIF.
  • jpeg has no alpha: transparent areas are flattened onto background (white by default).

Develop

npm install

npm test # builds, then node --test

src/engine.ts is the pure image layer (tested directly). src/index.ts adapts it to MCP tools.

Smithery release: scripts/build-mcpb.sh builds build/roundcut-mcp- .mcpb from mcpb/manifest.json (25 MB cap, so only the macOS arm64 and Windows x64 sharp binaries go in), then scripts/publish-smithery.sh uploads it with the tool schemas read from the built server.
