Complete Singapore law database — 523 Acts, 28K+ provisions from Singapore Statutes Online (sso.agc.gov.sg) with full-text search, definitions, and citation support

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.

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Retrieve specific provision by statute + chapter/section | | check_currency | Check if statute is in force, amended, or repealed | | validate_citation | Validate citation against database (zero-hallucination check) | | build_legal_stance | Aggregate citations from statutes for a legal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 | | about | Server info, capabilities, and coverage summary |

EU/International Law Integration Tools (5)

| Tool | Description | |------|-------------| | 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

This project uses multiple layers of automated security scanning:

| Scanner | What It Does | Schedule | |---------|-------------|----------| | CodeQL | Static analysis for security vulnerabilities | Weekly + PRs | | 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.
