PaperPilot is a PDF and document toolkit written in pure Rust. The same engine provides five forms: an MCP server, a CLI, a browser WASM build, a desktop app, and a local REST API. Files are processed entirely locally and are never uploaded to the cloud. The current v0.6 supports merging, splitting, rotating, compressing, OCR (based on pure-Rust PaddleOCR via rten), watermarking, signature verification, PII scanning, and Excel-to-JSON/CSV conversion. The MCP server can be connected directly to Claude Desktop or Cursor, enabling AI agents to perform PDF operations; the community edition is open source under Apache 2.0, while the enterprise edition (SSO, RBAC, audit logs, DLP) is developed separately.
