Open-Source-Legal/OpenContracts
Humans and AI agents, building knowledge bases together. Self-hosted document annotation, version control, semantic search, and MCP.
Combines configurable AI agents with structured human annotations through version-controlled document corpuses, enabling agents to reason over curated knowledge rather than generate unsupported claims. Built on PydanticAI for agent orchestration, vector embeddings for semantic search, and PAWLS for precise PDF coordinate mapping, with MCP server integration to expose knowledge bases to Claude, Cursor, and compatible tools. Supports threaded discussions, custom label schemas, multi-page span annotations, and public corpus forking for collaborative knowledge building across teams.
