PDF Tools - Fill, Sign, Merge, Split, Extract

PDF Tools turns Claude Desktop into a complete local PDF workstation. Instead of just opening a PDF, Claude can fetch PDFs from URLs, inspect them visually, fill forms, manage pages, add signature/date zones, apply local signatures or text, extract structured data, and analyze document content without uploading files to a web app.

This package targets Claude Desktop and other local MCP hosts today. It does not yet include a remote Claude/Cowork connector.

Interactive PDF Viewer: • View PDFs with page navigation, zoom, search, text selection, and fullscreen • See form fields in a sidebar with fill status • Use visual page management to reorder, rotate, and remove pages before saving • Switch into Sign mode to work with signature/date zones on the PDF

Sign Mode & Local Signatures: • Detect signature, initials, and date zones with visible coordinates Claude can reason from • Draw or reuse saved local signatures • Place signatures, dates, or other text on detected or custom zones • Inspect a region, preview it, and turn it into a typed signing zone when the automatic detector is not enough • Keep edits local, with active-document tracking and automatic backup behavior for same-file mutations

URL-to-PDF Workflows: • Fetch PDFs from HTTP(S) URLs to the user’s local machine, including cases where Claude’s WebFetch is blocked • Open downloaded PDFs immediately in the viewer for fill, sign, page management, extraction, or analysis • Use page-bounded reads, text search, page renders, and region renders instead of one brittle all-document operation

Forms & Reusable Profiles: • Fill W-9s, 1099s, rental applications, waivers, and any fillable PDF • Save personal or business details as reusable profiles • List, load, and apply saved profiles so repeated forms take seconds instead of minutes • Bulk fill many PDFs from CSV data and validate required fields before submission

Page Organization Tools: • Merge multiple PDFs into one document • Split PDFs by exact page ranges or regular intervals • Rotate and reorder pages, or apply a full page plan in one pass • Keep the original intact by saving organized output as a new file

Extraction, Rendering & Analysis: • Read document text for summarization, question answering, and research workflows • Read specific page ranges and search PDF text with page-numbered snippets • Render full pages or bounded regions to PNG for visual reasoning on scanned or image-heavy documents • Extract structured data to CSV • Inspect page-level details like orientation, text presence, images, and likely blank pages • Review metadata such as page count, dimensions, form fields, and file size

Local-first and user-controlled: PDFs, saved profiles, and signatures stay on the user’s machine. Claude Desktop users choose which folders PDF Tools may read from or write to.

Works with many PDF types: Forms, contracts, research papers, technical manuals, invoices, financial statements, scanned documents, municipal packets, and encrypted PDFs.

Best for: People who need more than a viewer — operators processing forms, lawyers organizing contracts, accountants handling tax documents, researchers reviewing papers, and anyone who wants local PDF workflows without sending files to a web app.
