office-oxide-mcp

Rust-native MCP server for Office document processing (Excel, Word, PowerPoint, PDF).
Sub-millisecond, local-first, open source — the "open source Aspose."

PDFs are a pain. We live in bureaucratic countries where every form asks for your name, address, and date of birth — over and over. Bank applications, tax forms, insurance claims, government permits, rental agreements. Same fields, different PDFs, endless typing.
Stop filling forms by hand. Let office-oxide-mcp do it in milliseconds — whether it's a simple AcroForm, a complex XFA form, or a flat scanned PDF where you need coordinates. Your LLM reads the form, you approve, it fills. Done.
