How to Install OpenContracts on Ubuntu 24.04

OpenContracts is an MIT-licensed, self-hosted document analytics and knowledge management platform. It ingests PDF, DOCX, and text documents into corpuses with folder hierarchies, permissions, and full version history. Teams can annotate documents, extract structured data with custom schemas, deploy AI agents powered by PydanticAI to search and analyze content, and expose everything through an MCP server to AI tools like Claude and Cursor. Features include: a pluggable parser/pipeline system, custom metadata schemas, human annotation interfaces, AI agents for document search and analysis, MCP server integration, data extraction across hundreds of documents, forum-style discussions, corpus automation triggers, and badge-based reputation systems. The platform is Docker-based with an MIT license, has 1400+ GitHub stars, and serves as a complete Document Management System (DMS) for the agentic world.
