Overview

Description from the maker (original English)

Compress, merge, convert, OCR, redact and sign PDFs, generate new ones, and read them with AI.

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: Computer or cloud
  • Transport: stdio, Streamable HTTP
  • Category: Other
  • You need to fill in: FYNEPDF_API_KEY, Authorization

Install

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

Before you install

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • Runs in the cloudNothing to install; it connects over the internet
  • 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 …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Or run it on your computer

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

{
  "mcpServers": {
    "fynepdf": {
      "command": "npx",
      "args": [
        "-y",

      ],
      "env": {
        "FYNEPDF_API_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add --transport http fynepdf https://api.fynepdf.com/mcp --header 'Authorization: your-value'

Or run it on your computer

claude mcp add fynepdf --env FYNEPDF_API_KEY=your-value -- npx -y @fynepdf/mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

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

    A FynePDF API key (fyne_live_… or fyne_test_…) from https://fynepdf.com/developers/dashboard
  • Authorization secret HTTP header
    Optional. Bearer and a FynePDF API key, instead of signing in with OAuth.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

  • search_docs

    Search the FynePDF API and MCP documentation: actions, parameters, pricing, files, jobs and errors.

  • list_actions

    Every action FynePDF can run on a file (the REST API's job steps), with what it takes, what it makes and its price in API credits.

  • app_ready

    FynePDF's in-chat cards say once which host bridge they run in, for diagnosis. Not for conversation.

  • preview_file

    The first pages of a PDF as images, for FynePDF's result viewer. Not needed in conversation: use get_file for a link.

  • upload_file

    Bring a file into FynePDF. Shows a drop zone where the app supports it (Claude, ChatGPT, VS Code); it takes several files at once, e.g. for a merge, and reports their file_ids in order. With file_name and size_bytes it also returns a signed upload_url and a ready curl command, fo

  • import_file_from_url

    Fetch a PDF, Office file, image or EPUB from a public link into FynePDF and get its file_id.

  • get_file

    A file's details and a fresh download link (valid 1 hour).

  • list_library_files

    Files saved in the person's FynePDF Library, newest first (pinned on top). Pass an id as library_file_id to any tool.

  • list_files

    Files on FynePDF from the last 24 hours, newest first: what the person dropped in the upload box, other uploads and imports, and results. Use it to find the file_id of a file the person says they uploaded, by its name.

  • save_to_library

    Keep a result in the person's FynePDF Library (fynepdf.com/library), so it isn't deleted after 24 hours.

  • merge_pdfs

    Join PDFs into one, in the order given (file_ids, then files, then file_urls). Each part gets a bookmark with its name.

  • split_pdf

    Split a PDF into parts by page ranges ("1-3", "4", "5-9") or into parts no bigger than max_part_mb. Returns a ZIP of the parts.

  • edit_pages

    Change a PDF's pages (counted from 1): delete pages, keep only some pages, put pages in a new order (pages left out are dropped), or rotate all pages or a range.

  • stamp_pdf

    Number the pages, stamp a text watermark on every page, or both in one go. Page number format uses %d twice, e.g. "Page %d of %d".

  • compress_pdf

    Make a PDF smaller: at a level (low, medium, high) or under a target size in MB. The result says whether the target was met.

  • protect_pdf

    lock: add a password needed to open it. unlock: remove a password you know. flatten: burn form fields and annotations into the page so they can't be changed.

  • redact_pdf

    Remove text for real, not just cover it: name the exact text to remove, or describe it ("all names, emails and account numbers") and FynePDF finds it. The result is checked: if any of the text can still be found, nothing is returned. The original file is kept.

  • convert_from_pdf

    Turn a PDF into Word (.docx), Excel or CSV (tables found on the page), images (PNG/JPEG in a ZIP), Markdown, EPUB, PDF/A (archival), LaTeX, or a grayscale PDF. For tables read by AI (scans, bank statements), use extract_data.

  • convert_to_pdf

    Make a PDF from Word, Excel or PowerPoint files, images (one page each, in order), an EPUB, or a public web page (url). For content you write yourself, use create_pdf.

  • ocr_pdf

    Add a text layer to scanned pages, so the text can be searched, copied and read by AI. Takes a scanned PDF or an image (a photo or scan as PNG, JPEG, TIFF, GIF, WebP or HEIC), which comes back as a searchable PDF. Reads 90 languages and finds the language itself; pass language on

  • create_pdf

    Turn Markdown or HTML you write into a well-set PDF: a report, invoice, letter, resume or plain document. Tables, headings, lists, images by URL and page breaks work; header, footer and page numbers are optional. For an invoice, resume or letter, prefer data (the fields, with tem

  • sign_pdf

    Stamp a signature image (PNG or JPEG) on a page: at a named spot (bottom-right by default) or at x and y in points from the top-left corner.

  • ask_pdf

    Answer a question from the document only, citing pages. Every quote is checked against the page text (verified: false marks one that couldn't be found).

  • summarize_pdf

    A plain summary and key points, each with the pages it comes from.

  • extract_data

    Read structured data with AI and check it in code: invoice (fields, lines and totals, added up), statement (bank transactions, balances compared), tables (every table, cell by cell), or schema (your own JSON Schema). Output json returns the data here; excel or csv also makes a sp

  • smart_edit

    Describe the change ("remove the blank pages, number the rest and make it PDF/A"): FynePDF plans the steps from its actions, checks the plan, and runs it. With run false it only returns the plan.

  • get_job

    Check a job that was still running, and get its files when it's done. Waits up to 50 seconds by default.

Common questions

Is FynePDF safe?

It passed 3 of 3 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?

You need to fill in: FYNEPDF_API_KEY, Authorization

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 6 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, Winecellarbuilders

FynePDF MCP server

Real PDF tools for Claude, ChatGPT, Cursor, VS Code and any other MCP client:

compress, merge, split, convert, OCR, redact, sign, create PDFs, and read them with AI.

https://api.fynepdf.com/mcp

FynePDF is a remote MCP server (Streamable HTTP). Add the URL to an assistant once, sign in with your FynePDF account, and it can work on PDFs itself: "compress this to under 5 MB", "redact every phone number", "turn these invoices into a spreadsheet".

This repository holds the server's registry entry, the local bridge (npx @fynepdf/mcp) and a Claude skill. The server itself runs at FynePDF; docs are at fynepdf.com/developers/docs/mcp.

Connect it

AssistantHow
Claude (web, desktop, mobile)Settings, Connectors, Add custom connector, paste the URL. Guide
ChatGPTTurn on Developer mode in Settings, Apps, then create an app with the URL. Guide
CursorAdd to Cursor
VS CodeAdd to VS Code
Claude Codeclaude mcp add --transport http fynepdf https://api.fynepdf.com/mcp
Gemini CLIgemini extensions install https://github.com/fynepdf/fynepdf-mcp

Any client that speaks remote MCP works the same way: give it the URL, and it signs in with OAuth the first time a tool needs your account. Work then counts against your fynepdf.com plan, as on the website. Agents of your own can send an API key as the bearer token instead; that spends API credits.

Local files: npx @fynepdf/mcp

A remote server can't see files on your computer. The bridge runs on your machine over stdio, passes everything through to the remote server with your API key, and adds two tools of its own:

  • upload_local_file: sends a file on this computer to FynePDF and returns its file_id.
  • download_file: saves a result to your Downloads folder (or a path you name). It never replaces an existing file unless told to.

Name the file by its path ("compress ~/Downloads/report.pdf"). A file attached to the chat goes to the assistant's own sandbox, not your computer, so the bridge can't read it.

"mcpServers": { "fynepdf": { "command": "npx", "args": ["-y", "@fynepdf/mcp"], "env": { "FYNEPDF_API_KEY": "fyne_live_..." } } } }

Get a key in the developer dashboard: test keys are free (results are watermarked), live keys get 250 free credits a month. More in packages/mcp.

Tools

ToolWhat it does
upload_fileBring a file in: a drop zone in Claude, ChatGPT and VS Code, or a signed upload link
import_file_from_urlFetch a PDF, Office file, image or EPUB from a public link
get_fileA file's details and a fresh download link
list_filesRecent files (last 24 hours), to find one the person just uploaded by name
list_library_files, save_to_libraryUse and keep files in your FynePDF Library
merge_pdfs, split_pdf, edit_pagesJoin, split, delete, keep, reorder and rotate pages
stamp_pdfPage numbers, a watermark, or both

protect_pdfLock with a password, unlock, or flatten
redact_pdfRemove text for real: exact text, or described ("all names and emails")
convert_from_pdfTo Word, Excel or CSV, images, Markdown, EPUB, PDF/A, LaTeX or grayscale
convert_to_pdfFrom Word, Excel, PowerPoint, images, EPUB or a web page
ocr_pdfMake a scan searchable
create_pdfA report, invoice, letter or resume from Markdown, HTML or data, with the figures checked
sign_pdfStamp a signature image on a page
ask_pdf, summarize_pdfAnswers and summaries citing pages, with quotes checked against the text
extract_dataInvoices, statements and tables as data, added up in code
smart_editDescribe the change; FynePDF plans the steps and runs them
get_job, search_docs, list_actionsLong jobs, the docs, and every action with its price

Every tool returns a file_id, so the next tool works on the result without downloading and uploading again. In Claude and ChatGPT a result also shows as a card with a preview, Download and Save to Library.

Files and privacy

Files live on FynePDF only while they're worked on: they're deleted after 24 hours unless you save them to your Library, and download links last 1 hour. Disconnect an assistant any time in the dashboard; it stops working at once. See the privacy policy.
