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

Run this in your terminal

claude mcp add stayput -- npx -y stayput-mcp

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "stayput": {
      "command": "npx",
      "args": [
        "-y",
        "stayput-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": {
    "stayput": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "stayput-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 StayPut 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 (0.1.0) reached the registry 41 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?

Stayput MCP server

Local PDF and photo tools for Claude, Cursor, VS Code and any other app that speaks the Model Context Protocol. Ask your assistant to merge PDFs, pull out pages, or remove the GPS location from a photo, and it does the work on your own machine.

It runs the same code as stayput.dev, the browser version. Your files are read from disk and written back to disk; nothing is uploaded, and the server makes no network requests. It is free and open source (MIT), with no account and no API key.

Tools

ToolWhat it does
merge_pdfsCombine PDFs into one, in the order given
extract_pdf_pagesKeep only some pages, reorder them ("3,1,2") or drop pages
split_pdfSplit into one file per page, or every N pages
rotate_pdfRotate all pages or chosen pages by 90, 180 or 270 degrees
number_pdf_pagesStamp page numbers, e.g. "Page {n} of {total}"
pdf_infoPage count, page sizes and title
images_to_pdfJPG and PNG images into one PDF, one per page, no re-compression
inspect_image_metadataShow GPS location, camera, capture time and other hidden metadata in a photo
strip_image_metadataWrite a copy of a JPG, PNG or WebP with EXIF, GPS, XMP and comments removed, without re-encoding

Every tool writes a new file and returns its path. Input files are never modified, and an existing file is never overwritten (you get file-1.pdf instead). Encrypted PDFs (bank statements, forms with printing restrictions) are decrypted locally with qpdf; for PDFs that need a password to open, the assistant passes it in the password argument.

Install

Requires Node.js 20 or newer.

Claude Code

claude mcp add stayput -- npx -y stayput-mcp

Claude Desktop, Cursor, Windsurf and other JSON configs (claude_desktop_config.json, .cursor/mcp.json, ...)

{

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

VS Code

code --add-mcp '{"name":"stayput","command":"npx","args":["-y","stayput-mcp"]}'

Then ask things like:

  • "Merge invoice-march.pdf and invoice-april.pdf in ~/Downloads"
  • "Take pages 2 to 5 out of contract.pdf"
  • "Does IMG_2041.jpg have a location in it? If so, make a copy without it"
  • "Number the pages of thesis.pdf, starting on page 3"

Relative paths are resolved from the folder the server was started in, so absolute paths or ~/... are the safest thing to give it.

Not covered here

HEIC, WebP and AVIF conversion, compression, PDF to image and PDF signing need a browser engine. They are on stayput.dev, which works the same way: in your browser, nothing uploaded.

Development

cd mcp

npm install npm test # builds dist/index.js and runs the end-to-end tests

The tests use the site's fixtures; generate them first from the repository root with python3 tests/fixtures/make-fixtures.py && node tests/fixtures/make-pdf.mjs (needs Pillow and pillow-heif).

The server imports the PDF and metadata code from ../src/lib and bundles it with esbuild (build.mjs). Two browser-only modules are swapped at build time: src/unlock.ts loads qpdf from node_modules instead of a tag, and src/no-canvas.ts stands in for the canvas helpers that only PDF compression uses.
