FynePDF

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

Assistant	How
Claude (web, desktop, mobile)	Settings, Connectors, Add custom connector, paste the URL. Guide
ChatGPT	Turn on Developer mode in Settings, Apps, then create an app with the URL. Guide
Cursor	Add to Cursor
VS Code	Add to VS Code
Claude Code	claude mcp add --transport http fynepdf https://api.fynepdf.com/mcp
Gemini CLI	gemini 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.

Tools

Tool	What it does
upload_file	Bring a file in: a drop zone in Claude, ChatGPT and VS Code, or a signed upload link
import_file_from_url	Fetch a PDF, Office file, image or EPUB from a public link
get_file	A file's details and a fresh download link
list_files	Recent files (last 24 hours), to find one the person just uploaded by name
list_library_files, save_to_library	Use and keep files in your FynePDF Library
merge_pdfs, split_pdf, edit_pages	Join, split, delete, keep, reorder and rotate pages
stamp_pdf	Page numbers, a watermark, or both
compress_pdf	Smaller at a level, or under a target size
protect_pdf	Lock with a password, unlock, or flatten
redact_pdf	Remove text for real: exact text, or described ("all names and emails")
convert_from_pdf	To Word, Excel or CSV, images, Markdown, EPUB, PDF/A, LaTeX or grayscale
convert_to_pdf	From Word, Excel, PowerPoint, images, EPUB or a web page
ocr_pdf	Make a scan searchable
create_pdf	A report, invoice, letter or resume from Markdown, HTML or data, with the figures checked
sign_pdf	Stamp a signature image on a page
ask_pdf, summarize_pdf	Answers and summaries citing pages, with quotes checked against the text
extract_data	Invoices, statements and tables as data, added up in code
smart_edit	Describe the change; FynePDF plans the steps and runs them
get_job, search_docs, list_actions	Long 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.
