# Pagus

> Pagus is an open-source, modular PPTX web renderer. It parses PowerPoint (.pptx) files and renders them in the browser or Node.js as SVG — with no server-side conversion and no Microsoft Office or LibreOffice dependencies. Pagus ships a framework-agnostic core, a React component library, a deck authoring API, and a Model Context Protocol (MCP) server for inline preview inside Claude Desktop and other AI clients.

Pagus is released under the MIT license and published on npm under the `@pagus-kit` scope. Source code lives at https://github.com/pagus-kit/pagus.

## What makes Pagus different

- **Pure client-side**: no server, no Office install, no headless conversion step.
- **SVG + DOM hybrid**: shapes as SVG paths, text and tables wrapped in `<foreignObject>` so they remain selectable, copyable, and searchable.
- **Framework-agnostic core**: the renderer is a pure function returning SVG strings, usable in any framework or in headless Node.js pipelines.
- **Agent-ready**: the MCP server makes Pagus a first-class tool for Claude and other MCP clients; the builder API lets agents produce decks programmatically.
