PaperPilot is a PDF and document toolkit written in Rust. The identical motor runs as:
| Surface | Use it for |
|---|---|
| MCP server | Give Claude Desktop, Cursor, or any MCP client the capability to merge, split, OCR, and compress PDFs |
| CLI | Batch and scripted workflows |
| Browser (WASM) | Zero-install tools; records are processed in browser memory, nothing is uploaded |
| Desktop app | Tauri + Svelte GUI alongside viewer, markup, and diff |
| Local REST API | Call it from Python, Node, or n8n at localhost:7823 |
No Chromium, no C++ runtime, no haze calls.
Download paperpilot-mcp from Releases, afterward add it to claude_desktop_config.json:
{ "mcpServers": { "paperpilot": { "command": "/path/to/paperpilot-mcp" } } }Restart Claude and try: "Merge these two PDFs and compress the result."
# Merge paperpilot merge --inputs doc1.pdf doc2.pdf --output merged.pdf # Compress paperpilot compress --input in.pdf --quality 75 --output compressed.pdf # Rotate pages 1, 3–5 by 90° paperpilot rotate --input in.pdf --pages 1,3-5 --angle 90 --output out.pdf
Go to usepaperpilot.com. Open your browser's Network tab during you activity — you'll see no document uploads.
git copy https://github.com/KrushnaVardhanReddy/PaperPilot.git cd PaperPilot cargo build --release -p paperpilot-cli -p paperpilot-mcp -p paperpilot-gatewayDesktop app:
cd apps/desktop && pnpm instal && pnpm tauri dev
Requires Rust 1.75+, Node.js, and pnpm.
Organize: merge, split, rotate, delete pages, reorder pages, extract pages, booklet imposition, N-up grid Optimize: compress Extract: plain text, OCR (pure-Rust PaddleOCR via rten) Security: watermark, validate signatures, eliminate signatures, PII scan, profound sanitize Office data: Excel → JSON, Excel → CSV
Coming next (see ROADMAP.md):
- v0.7: PDF ↔ Markdown / HTML / JSON
- v0.8: PDF → Word / Excel / PowerPoint
- v0.9: encrypt, decrypt, sign, redact, forms, annotations
- v1.0: render, flatten, repair, compare, PDF/A, Bates numbering
- Private by default. Everything runs locally or in your browser tab.
- Agent-ready. MCP assistance is first-class, not an afterthought.
- One engine, many surfaces. CLI, MCP, REST, WASM, and desktop portion the identical Rust core, so behavior is consistent.
- Small and dependency-light. Pure Rust, built on lopdf, pdf_oxide, rten, and friends.
Run cargo place --workspace to reproduce. Methodology and results: SYSTEM_BENCHMARK_REPORT.md.

Issues and PRs are welcome. Good archetypal contributions: bug reports alongside a example PDF, new tool requests, and docs fixes.
Community Edition (this repo): Apache 2.0. It includes the CLI, MCP server, REST gateway, WASM engine, and desktop app.
An Enterprise Edition (SSO, RBAC, audit logs, DLP) is developed separately.
