Verified data only -- every citation is validated against official sources (peraturan.bpk.go.id, jdih.kemenkumham.go.id). Zero LLM-generated content.

Why This Works

Verbatim Source Text (No LLM Processing):

• All statute text is ingested from peraturan.go.id and jdih.kemenkumham.go.id official sources using a census-first full corpus approach (BPK RI + JDIH Nasional)
• Provisions are returned unchanged from SQLite FTS5 database rows
• Zero LLM summarization or paraphrasing -- the database contains law text, not AI interpretations

Smart Context Management:

• Search returns ranked provisions with BM25 scoring (safe for context)
• Provision retrieval gives exact text by law number + pasal (article)
• Cross-references help navigate without loading everything at once

Technical Architecture:

JDIH BPK / peraturan.go.id --> Parse --> SQLite --> FTS5 snippet() --> MCP response
                                  ^                        ^
                           Provision parser         Verbatim database query

Traditional Research vs. This MCP

Pendekatan Tradisional	Server MCP ini
Cari di peraturan.go.id berdasarkan nomor UU	Cari dalam Bahasa Indonesia: "pelindungan data pribadi"
Navigasi manual UU multi-pasal	Dapatkan ketentuan yang tepat dengan konteks
Referensi silang manual antar UU	build_legal_stance mengagregasi dari berbagai sumber
"Apakah UU ini masih berlaku?" -- periksa manual	Alat check_currency -- jawaban dalam hitungan detik
Temukan kerangka ASEAN -- cari manual	get_eu_basis -- kerangka internasional terkait langsung
Tanpa API, tanpa integrasi	Protokol MCP -- native AI

Tradisional: Cari di JDIH --> Unduh PDF --> Ctrl+F dalam Bahasa Indonesia --> Referensi silang UU lain --> Periksa kerangka ASEAN secara terpisah --> Ulangi

MCP ini: "Apa kewajiban pemrosesan data berdasarkan UU PDP No. 27/2022 dan bagaimana selarasnya dengan standar internasional?" --> Selesai.

International Law Alignment

Indonesia is not an EU member state. Indonesian law aligns with international frameworks through:

• ASEAN framework -- Indonesia is a founding ASEAN member and the largest economy; digital economy and data protection laws (UU PDP) align with ASEAN frameworks
• G20 -- Indonesia holds G20 membership; financial regulation and data governance align with G20 commitments
• WTO -- Trade, intellectual property, and e-commerce law follows WTO commitments
• UNCITRAL -- Electronic transactions framework follows UNCITRAL model law principles
• Perhimpunan Advokat Indonesia (PERADI) / Kongres Advokat Indonesia (KAI) -- Professional legal practice regulated by PERADI and KAI

The international bridge tools allow you to explore these alignment relationships -- checking which Indonesian provisions correspond to ASEAN or G20 requirements, and vice versa.

Note: International cross-references reflect alignment and treaty obligation relationships. Indonesia adopts its own legislative approach, and the tools help identify where Indonesian and international law address the same domains.

Important Disclaimers

Legal Advice

THIS TOOL IS NOT LEGAL ADVICE

Statute text is sourced from JDIH BPK RI and peraturan.go.id official databases. However:

• This is a research tool, not a substitute for professional legal counsel
• Court case coverage is not included -- do not rely solely on this for jurisprudence research
• Verify critical citations against primary sources (peraturan.go.id) for official proceedings
• International cross-references reflect alignment relationships, not formal transposition
• Regional/local regulations (Perda) are not included -- this covers national Undang-Undang only
• For professional legal advice in Indonesia, consult a member of PERADI (Perhimpunan Advokat Indonesia) or KAI (Kongres Advokat Indonesia)
