PDF tools for your AI agent — and for you. Pure Rust. Runs locally. Files never leave your machine. Try it in your browser → · Download · Roadmap PaperPilot is a PDF and document toolkit written in Rust. The same engine runs as: Surface Use it for MCP server Give Claude Desktop, Cursor, or any MCP client the ability to merge, split, OCR, and compress PDFs CLI Batch and scripted workflows Browser (WASM) Zero-install tools; files are processed in browser memory, nothing is uploaded Desktop app Tauri + Svelte GUI with viewer, markup, and diff Local REST API Call it from Python, Node, or n8n at localhost:7823 No Chromium, no C++ runtime, no cloud calls. Quick start 1. Use it with Claude / Cursor (MCP) Download paperpilot-mcp from Releases, then 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."

Use the CLI # 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 3.

Build from source git clone https://github.com/KrushnaVardhanReddy/PaperPilot.git cd PaperPilot cargo build --release -p paperpilot-cli -p paperpilot-mcp -p paperpilot-gateway Desktop app: cd apps/desktop && pnpm install && pnpm tauri dev Requires Rust 1.75+, Node.js, and pnpm. What it can do today (v0.6) 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, remove signatures, PII scan, deep 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 Why another PDF tool? Private by default. Everything runs locally or in your browser tab. Agent-ready. MCP support is first-class, not an afterthought. One engine, many surfaces. CLI, MCP, REST, WASM, and desktop share the same Rust core, so behavior is consistent. Small and dependency-light. Pure Rust, built on lopdf, pdf_oxide, rten, and friends. Benchmarks Run cargo bench --workspace to reproduce. Methodology and results: SYSTEM_BENCHMARK_REPORT.md.

Contributing Issues and PRs are welcome. Good first contributions: bug reports with a sample PDF, new tool requests, and docs fixes. License 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.
