Malaysian Law MCP Server

The Laws of Malaysia alternative for the AI age.

Query 589 Malaysian federal statutes -- from the Computer Crimes Act and Anti-Money Laundering Act to the Employment Act, Income Tax Act, and more -- directly from Claude, Cursor, or any MCP-compatible client.

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

Built by Ansvar Systems -- Stockholm, Sweden

Why This Exists

Malaysian legal research is scattered across the AGC portal (lom.agc.gov.my), CommonLII, and various government gazettes. Whether you're:

• A lawyer validating citations in a brief or contract
• A compliance officer checking data protection or AML obligations
• A legal tech developer building tools on Malaysian law
• A researcher tracing legislative provisions

...you shouldn't need to navigate multiple sources and PDFs manually. Ask Claude. Get the exact provision. With context.

This MCP server makes Malaysian law searchable, cross-referenceable, and AI-readable.

Example Queries

Once connected, just ask naturally:

• "What does the Computer Crimes Act 1997 say about unauthorised access?"
• "Find provisions about money laundering in Malaysian law"
• "What are the penalties under the Anti-Money Laundering Act 2001?"
• "Show me Section 2 of the Employment Act 1955 -- the definitions"
• "What does the Communications and Multimedia Act say about licensing?"
• "Find provisions about evidence and computer documents"
• "What are the offences under the Arms Act?"

What's Included

Verified data only -- every provision is ingested from CommonLII (AustLII), which hosts the official English text of Malaysian consolidated statutes. Zero LLM-generated content.

Note: The CommonLII Malaysian legislation database was last updated in March 2010. Acts enacted after that date (e.g., PDPA 2010, Companies Act 2016) are not yet available from this source. A future update will supplement from AGC (lom.agc.gov.my) for post-2010 legislation.

Why This Works

Verbatim Source Text (No LLM Processing):

• All statute text is ingested from CommonLII official sources
• Provisions are returned unchanged from SQLite FTS5 database rows
• Zero LLM summarization or paraphrasing -- the database contains regulation text, not AI interpretations

Smart Context Management:

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

Technical Architecture:

CommonLII Index --> Census --> Ingest --> Parse --> SQLite --> FTS5 snippet() --> MCP response

Malaysian Legal System Context

• Legal system: Mixed -- common law (British heritage), Islamic law (Syariah), and customary law (adat)
• Language: Malay is official; the Malay text prevails in case of conflict (National Language Act 1963/67). However, legislation is available in both Malay and English.
• Act numbering: Federal legislation uses "Act NNN" identifiers (e.g., Act 709 = PDPA 2010)
• Structure: Sections (not Articles) -- common law tradition (s1, s2, s3...)
• Key regulators: PDP Commissioner, MCMC, Bank Negara Malaysia, Securities Commission
• ASEAN member: Participates in ASEAN Framework on Personal Data Protection

Data Sources & Freshness

All content is sourced from authoritative legal databases:

• CommonLII -- AustLII's free legal information institute, hosting consolidated Malaysian statutes
• AGC Malaysia -- Official Attorney General's Chambers portal (planned for post-2010 supplement)

Census-Driven Ingestion

The ingestion pipeline uses a census-first approach:

Legal Advice

THIS TOOL IS NOT LEGAL ADVICE

Statute text is sourced from CommonLII's consolidated collection. However:

• This is a research tool, not a substitute for professional legal counsel
• Coverage is limited to pre-2010 legislation -- PDPA 2010 and later Acts are not yet included
• Verify critical citations against primary sources (lom.agc.gov.my) for court filings
• The Malay text prevails in case of conflict between English and Malay versions
