## The Problem
280 million Indonesians have no practical way to read their own laws. The official legal database (peraturan.go.id) offers only PDF downloads: no search, no structure, no API. When you ask AI about Indonesian law, you get hallucinated articles and wrong citations because no grounded data source exists.
## Try It Now
Connect Claude to real Indonesian legal data in one command:
bash
claude mcp add --transport http pasal-id https://pasal-mcp-server-production.up.railway.app/mcp
Then ask:
> "Apa saja hak pekerja kontrak menurut UU Ketenagakerjaan?" (What are contract worker rights under the Labor Law?)
> "Jelaskan pasal tentang perlindungan data pribadi" (Explain articles on personal data protection)
> "Apakah UU Perkawinan 1974 masih berlaku?" (Is the 1974 Marriage Law still in force?)
Claude searches 40,000+ regulations and 937,000+ structured articles, cites specific Pasal (articles), and gives grounded answers. No hallucination.
Or browse the web app at pasal.id.

## How Opus 4.6 Powers the Platform
The entire codebase, from the Next.js frontend to the MCP server to the data pipeline, was built with Claude Opus 4.6 via Claude Code during the hackathon period. But Opus 4.6 isn't just the development tool. It's embedded in the product itself, running a self-improving correction flywheel that makes the platform more accurate over time:
