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

PaperPilot is a pure-Rust PDF and document toolkit that runs locally without cloud dependencies, offering zero-installation processing directly in browsers via WASM and integrating with AI tools through MCP servers, CLI, desktop apps, and local REST APIs. The engine enables users to merge, split, OCR, and compress PDFs while ensuring files never leave their machines. It can be used with Claude Desktop, Cursor, or other MCP clients, as well as through command-line workflows and a browser-based interface.
