IURA Plugins for Claude

Open-source plugins that turn Claude into a legal specialist for legal professionals. Works best with Claude Cowork, also compatible with Claude Code.

The plugins work standalone — contract review, NDA triage, NDA generation, and bulk document review are fully functional without any external services. Each skill encodes deep domain expertise in Polish (and soon Dutch) law: negotiation playbooks, risk classification, citation standards, and professional output formats.

Why IURA MCP?

AI models hallucinate legal citations. They invent case law signatures, cite outdated statutes, and fabricate court rulings that don't exist. For casual use this is tolerable, but for legal work it's a dealbreaker.

IURA MCP solves this by connecting Claude to 1.5M+ verified Polish legal documents in real time. With IURA MCP connected, your analysis includes:

• Real case law citations — verified signatures from Supreme Court, common courts, administrative courts, Constitutional Tribunal, and KIO
• Current legislation — actual text of statutes as in force today, not from training data
• Divergent case law lines — present both sides of a legal debate with real citations
• Tax interpretations — official positions from tax authorities with full signatures

The plugins are great standalone. With IURA MCP, they're complete.

How Plugins Work

plugin-name/
├── .claude-plugin/plugin.json   # Manifest
├── .mcp.json                    # Tool connections (IURA MCP)
├── commands/                    # Slash commands you invoke explicitly
└── skills/                      # Domain knowledge Claude draws on automatically

• Skills encode domain expertise and workflows Claude draws on automatically.
• Commands are explicit actions you trigger (e.g., /review-contract).
• Connectors wire Claude to external tools via MCP servers.
