Dura Lex is an open-source operating system for legal data.

It structures public legal data — legislation, case law, company registries, administrative guidance — into a jurisdiction-agnostic corpus, queryable by AI agents via MCP and by humans via a web portal.

A jurisdiction-agnostic kernel, jurisdiction plugins (France and EU today, designed for any country), a robust ingestion pipeline, and services on top. The schema follows the OpenStreetMap model — six universal structural kinds, JSONB tags, zero schema migration to add a jurisdiction.

Everything is published as Python libraries (MIT). The kernel, the corpus protocol, the jurisdiction drivers, the ingestion framework — all are composable packages that can be embedded in any application. Use the MCP server as-is, or import the libraries directly to build your own legal data product.
