What it does

The MCP package works with PDFs on your computer: it downloads a file from a link, shows it in an interactive viewer, fills forms, merges and splits documents, reorders pages and extracts structured data. Tools such as `fill_pdf`, `read_pdf_fields` and `bulk_fill_from_csv` fill forms, including in bulk from CSV, and saved profiles speed up repeated forms. Sign mode finds signature, initials, name and date zones, places a drawn or saved signature and prepares a handoff receipt. Optional sending to Lumin e-signing happens only after the exact confirmation of the user. Claude Desktop installs through a `.mcpb` file, Cursor and other hosts use an entry with a `node` command and there is a plugin for ChatGPT and Codex.

Who it is for. People who regularly fill, sign and assemble PDFs and want to do it locally through an assistant.

Good fit when

  • W-9 or application forms are filled from a saved profile in seconds.
  • Many PDFs must be filled from a CSV table and required fields validated.
  • Several files are merged, pages reordered and a new copy saved.
  • A document with signature zones is prepared for e-signing.

Not a fit when

  • You need a remote connector for Claude Cowork or the web version: none exists yet.
  • Documents must not be shown to the host and model: text and images go back to the host.
  • You need fully configured e-signing with no maintainer involvement.

Example request

Fill this PDF from my saved profile, place a signature and date in the detected zones and save a new copy.

Limitations

The package works locally but text, images and metadata it returns are processed by your host and model provider, so there is no zero upload. By default `~/Documents`, `~/Downloads` and `~/Desktop` are allowed and other folders are added in the Allowed PDF Directories setting. Lumin signing is configured by the installation maintainer and a personal Lumin account alone is not enough. For a host with broad filesystem access the permission boundary stays with the host.

How to disable. Remove the extension in Claude Desktop settings or the `pdf-tools` entry from the host config; profiles and signatures live in the extension private store.

FAQ

How do I install it in Claude Desktop?

Download the `.mcpb` from the latest release and double-click the file. The extension is also in the Claude extensions directory.

How do I connect it to Cursor?

Add a `pdf-tools` server with the `node` command and the path `/full/path/to/PDF-Tools/server/index.js` to `mcpServers`.

Which folders are accessible?

By default `~/Documents`, `~/Downloads` and `~/Desktop`. In Claude Desktop other folders go into the Allowed PDF Directories field.

Do documents go to a third-party service?

No, files are processed on the computer. Only a Lumin tool call sends the prepared PDF and addresses after your exact confirmation.

Can I fill many forms at once?

Yes, `bulk_fill_from_csv` fills a batch of PDFs from a CSV table and validates required fields before submission.
