PaperPilot gives coding agents local PDF tools with no cloud uploads

PaperPilot is an open-source PDF toolkit written in Rust that runs as an MCP server for Claude Desktop, Cursor and other MCP clients, plus a CLI, a browser WASM build, a desktop app and a local REST API on localhost:7823. It merges, splits, rotates, compresses and OCRs PDFs on your machine; the project says files never leave the device, and the browser demo at usepaperpilot.com processes files in memory with no upload. Current v0.6 also covers watermarks, signature checks, PII scan, deep sanitize and Excel to JSON or CSV. It is pure Rust with no Chromium or C++ runtime.
