Singapore Law MCP Server

The SSO alternative for the AI age.

Query 523 Singapore Acts -- from the Personal Data Protection Act and Cybersecurity Act to the Companies Act, Computer Misuse Act, and more -- directly from Claude, Cursor, or any MCP-compatible client.

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

Built by Ansvar Systems -- Stockholm, Sweden

Why This Exists

Singapore legal research is scattered across Singapore Statutes Online (SSO), the Attorney-General's Chambers, and LawNet. Whether you're:

• A lawyer validating citations in a brief or contract under Singapore law
• A compliance officer checking PDPA obligations for data processing in Singapore
• A legal tech developer building tools on Singapore legislation
• A researcher tracing legislative amendments across the revised edition

...you shouldn't need dozens of browser tabs and manual PDF cross-referencing. Ask Claude. Get the exact provision. With context.

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

Estimated database size: ~80-150 MB (full corpus of Singapore federal legislation)

Available Tools (13)

Core Legal Research Tools (8)

Tool	Description
search_legislation	FTS5 full-text search across all provisions with BM25 ranking
get_provision	Retrieve specific provision by statute + chapter/section
check_currency	Check if statute is in force, amended, or repealed
validate_citation	Validate citation against database (zero-hallucination check)
build_legal_stance	Aggregate citations from statutes for a legal topic
format_citation	Format citations per Singapore conventions (full/short/pinpoint)
list_sources	List all available statutes with metadata

get_eu_basis	Get EU directives/regulations for Singapore statute
get_singapore_implementations	Find Singapore laws implementing EU act
search_eu_implementations	Search EU documents with Singapore implementation counts
get_provision_eu_basis	Get EU law references for specific provision
validate_eu_compliance	Check implementation status of EU directives

Why This Works

Verbatim Source Text (No LLM Processing):

• All statute text is ingested from official Singapore government 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 statute identifier + chapter/section
• Cross-references help navigate without loading everything at once

Technical Architecture:

Official Sources --> Parse --> SQLite --> FTS5 snippet() --> MCP response
                     ^                       ^
              Provision parser         Verbatim database query

Traditional Research vs. This MCP

Traditional Approach	This MCP Server
Search official databases by statute number	Search by plain language
Navigate multi-chapter statutes manually	Get the exact provision with context
Manual cross-referencing between laws	build_legal_stance aggregates across sources
"Is this statute still in force?" --> check manually	check_currency tool --> answer in seconds
Find EU basis --> dig through EUR-Lex	get_eu_basis --> linked EU directives instantly
No API, no integration	MCP protocol --> AI-native

Data Sources & Freshness

All content is sourced from authoritative Singapore legal databases:

• Singapore Statutes Online -- Official Singapore government legal database

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

Security

Semgrep	SAST scanning (OWASP top 10, secrets, TypeScript)	Every push
Gitleaks	Secret detection across git history	Every push
Trivy	CVE scanning on filesystem and npm dependencies	Daily
Socket.dev	Supply chain attack detection	PRs
Dependabot	Automated dependency updates	Weekly

Important Disclaimers

Legal Advice

THIS TOOL IS NOT LEGAL ADVICE

Statute text is sourced from official Singapore government publications. However:

• This is a research tool, not a substitute for professional legal counsel
• Court case coverage is limited -- do not rely solely on this for case law research
• Verify critical citations against primary sources for court filings
• EU cross-references are extracted from statute text, not EUR-Lex full text

Before using professionally, read: DISCLAIMER.md | SECURITY.md

Client Confidentiality

Queries go through the Claude API. For privileged or confidential matters, use on-premise deployment.
