Indonesian Law MCP Server

The JDIH BPK (Jaringan Dokumentasi dan Informasi Hukum) alternative for the AI age.

Cari 1.924 Undang-Undang (UU) Indonesia -- dari UU Pelindungan Data Pribadi (UU PDP No. 27/2022) dan Kitab Undang-Undang Hukum Pidana (KUHP) hingga UU Ketenagakerjaan, UU ITE, dan lebih banyak lagi -- langsung dari Claude, Cursor, atau klien MCP apa pun.

If you're building legal tech, compliance tools, or doing Indonesian legal research, this is your verified reference database.

Built by Ansvar Systems -- Stockholm, Sweden

Mengapa alat ini ada

Penelitian hukum Indonesia tersebar di peraturan.go.id, jdih.kemenkumham.go.id, BPK RI, dan portal JDIH kementerian yang berbeda-beda. Baik Anda:

• Seorang pengacara memvalidasi kutipan dalam dokumen hukum atau kontrak
• Seorang profesional kepatuhan memeriksa kewajiban UU PDP atau peraturan OJK
• Seorang pengembang legaltech membangun alat berdasarkan hukum Indonesia
• Seorang peneliti melacak peraturan perundang-undangan Indonesia di 1.924 UU

...Anda seharusnya tidak memerlukan puluhan tab browser dan pencarian PDF manual. Tanyakan kepada Claude. Dapatkan ketentuan yang tepat. Dengan konteks.

Server MCP ini membuat hukum Indonesia dapat dicari, dapat direferensikan, dan dapat dibaca oleh AI.

• "Apa isi Pasal 30 KUHP tentang pidana denda?"
• "Temukan ketentuan tentang pemutusan hubungan kerja dalam UU Ketenagakerjaan"
• "Apakah UU ITE No. 11/2008 masih berlaku?"
• "Cari kewajiban keamanan data dalam UU PDP"
• "Apa persyaratan persetujuan dalam UU Perlindungan Konsumen?"

What's Included

Key Laws Included

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

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.

Core Legal Research Tools (8)

International Law Integration Tools (5)

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.

Data Sources & Freshness

All content is sourced from authoritative Indonesian legal databases:

• peraturan.go.id -- Official Indonesian government regulation portal
• JDIH BPK RI (peraturan.bpk.go.id) -- Badan Pemeriksa Keuangan legal information network (primary source)
• JDIH Kemenkumham -- Ministry of Law and Human Rights legal information network

Data Provenance

Automated Freshness Checks

A GitHub Actions workflow monitors all data sources:

Verified data only -- every citation is validated against official sources. Zero LLM-generated content.

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)
