PaperPilot – Zero-Cloud, Pure-Rust PDF Engine with WASM and MCP

Open your browser's Network tab while you work — you'll see no file uploads. 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. 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 Private by default. Everything runs locally or in your browser tab. MCP support is first-class, not an afterthought. CLI, MCP, REST, WASM, and desktop share the same Rust core, so behavior is consistent. Pure Rust, built on lopdf, pdf_oxide, rten, and friends. Run cargo bench --workspace to reproduce. Methodology and results: SYSTEM_BENCHMARK_REPORT. md.

Issues and PRs are welcome. Good first contributions: bug reports with a sample 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.
