Markdownify is an MCP server that provides AI agents with tools to convert various file types and web content into Markdown format. It uses markitdown (with Python dependencies and virtual environment) to process PDFs, images, audio files with transcription, DOCX/XLSX/PPTX documents, and web content including YouTube transcripts. The server exposes these conversion capabilities as MCP tools that can be invoked by AI coding assistants like Claude Desktop.
