Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

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

Run this in your terminal

claude mcp add fitfilesize -- npx -y fitfilesize-mcp

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "fitfilesize": {
      "command": "npx",
      "args": [
        "-y",
        "fitfilesize-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": {
    "fitfilesize": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "fitfilesize-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.

Common questions

Is FitFileSize 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 (0.2.1) reached the registry 20 days 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?

FitFileSize MCP server

Let your AI assistant make a PDF or image fit an upload limit, or a form's exact rules, with FitFileSize.

"Make ~/Downloads/signature.jpg fit the IBPS signature rules"

Saved ~/Downloads/signature.fit.jpg for IBPS signature (JPEG, 140 × 60 pixels, 10 KB to 20 KB): 10,240 bytes (10.0 KB), under the 20,000 bytes limit.

Any limit: "get this scan under 300 KB", "this photo under 50 KB".
Form presets: US visa photo (DS-160), Indian e-Visa passport page and photo, IBPS, SBI, RRB, SSC, NEET, JEE Main, CUET and GATE uploads, IRCC documents, and Discord emoji, profile banners and message uploads. The preset sets the size limit, the minimum size and the exact pixels. Ask for list_forms to see them all.
Several files at once: "fit these five documents under 2 MB each".
Keeps as much quality as the limit allows, and saves the result next to the original as .fit. . Every file keeps its format (a PNG stays a PNG) unless you say a JPEG is fine; iPhone HEIC photos come back as JPEG.
Free, no account, no API key. Files up to 50 MB.

Setup

Needs Node.js 20.10 or newer. Step-by-step setup with copy buttons: fitfilesize.com/claude.html.

Claude Code

claude mcp add fitfilesize -- npx -y fitfilesize-mcp

Claude Desktop, Cursor, Windsurf and other clients that use an mcpServers config file:

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

(Claude Desktop: Settings → Developer → Edit Config. Cursor: ~/.cursor/mcp.json.)

VS Code (.vscode/mcp.json):

"servers": { "fitfilesize": { "command": "npx", "args": ["-y", "fitfilesize-mcp"] } } }

Tools

`fit_file`

Argument
`path`	Full path to the file (`~/` works). PDF, JPEG, PNG, WebP, TIFF, BMP or HEIC (returned as JPEG), up to 50 MB.
`paths`	Instead of `path`: up to 10 files that share the same limit. Each is saved beside its original; one that fails is reported without stopping the rest.
`limit`	The upload limit, like `"200KB"` or `"1.5MB"`. KB and MB are 1000-based, so the result passes a check done either way.
`form`	Instead of `limit`: a form preset from `list_forms`, like `"ibps-photo"`.
`width`, `height`	Optional exact pixel size, images only.
`fit`	`"crop"` (default) or `"pad"` with white, when the pixel size changes the shape.
`minimum`	Optional smallest size, like `"10KB"`. A small JPEG is padded up to it; the picture is unchanged.
`jpeg_ok`	Optional. `true` lets a PNG, WebP, TIFF or BMP come back as a JPEG when that is what fits. Off by default; when it would have helped, the result says so.
`output`	Optional path for the result, with `path` only.

`list_forms`

The form presets, each with its rules and the official source they come from. The list is read from fitfilesize.com/forms.json, so new forms appear without an update; a copy is bundled for when the site cannot be reached.

Privacy

The file is sent to FitFileSize's server over HTTPS, compressed there, and deleted as soon as the result is saved on your computer. Requests name the package and its version (fitfilesize-mcp/0.2.1), nothing about you. Nothing else leaves your machine. See the privacy page. Uploads count against the site's free limit of 30 an hour.

Development

npm install

npm test # the tools through an MCP client, against a stand-in API npm run build # bundles the form presets from the website's data

FITFILESIZE_API points the server at another API, such as a local one (http://127.0.0.1:8000).

Licence

MIT, see LICENSE. This covers the MCP server in this folder; the rest of the FitFileSize repository is not open source.
