OpenContracts is a self-hosted, MIT-licensed document intelligence platform that turns document repositories into a programmable citation graph with human annotation, structured extraction, and AI agents. It exposes the same corpus through a GraphQL/REST API, an MCP server for AI tools like Claude and Cursor, and a React UI.

Use cases

• build a searchable knowledge base from PDFs and DOCX files
• extract structured data fields across hundreds of documents with LLMs
• annotate documents by hand and with AI agents
• expose a document corpus to Claude or Cursor via MCP
• run agents that search and answer questions over a document corpus
• self-host a document management system with fine-grained permissions
• fork and version-control shared document corpuses

When to choose

• you need self-hosted document ingestion, annotation, and LLM-powered extraction in one platform
• you want to give AI agents structured access to a document corpus via MCP or API
• your team needs human-in-the-loop annotation alongside automated extraction
• you need multi-format (PDF/DOCX/text) parsing with a pluggable pipeline

When to avoid

• you only need simple full-text search without annotation or extraction
• you want a lightweight library to embed in your own app rather than a full platform
• you need a fully managed SaaS with no self-hosting overhead
• your documents are mostly spreadsheets or images rather than text documents
