Nigerian Law MCP Server

The LawPavilion alternative for the AI age.

Query Nigerian legislation -- covering data protection, cybersecurity, corporate law, and more -- directly from Claude, Cursor, or any MCP-compatible client.

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

Built by Ansvar Systems -- Stockholm, Sweden

Why This Exists

Nigerian legal research is scattered across official government databases, commercial legal platforms, and institutional archives. Whether you're:

• A lawyer validating citations in a brief or contract
• A compliance officer checking if a statute is still in force
• A legal tech developer building tools on Nigerian law
• A researcher tracing legislative history

...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 Nigerian law searchable, cross-referenceable, and AI-readable.

Example Queries

Once connected, just ask naturally:

• "What does the Nigerian data protection law say about consent?"
• "Search for cybersecurity requirements in Nigerian legislation"
• "Is this statute still in force?"
• "Find provisions about personal data in Nigerian law"
• "What EU directives does this Nigerian law implement?"
• "Which Nigerian laws implement the GDPR?"
• "Validate this legal citation"
• "Build a legal stance on data breach notification requirements"

Cybercrimes (Prohibition, Prevention, etc.) Act	2015	One of Africa's most comprehensive cybercrime laws, influenced by the Budapest Convention
National Information Technology Development Agency (NITDA) Act	2007	Establishes NITDA for IT development policy and regulation
Companies and Allied Matters Act (CAMA)	2020	Modernised Nigerian company law, replacing CAMA 1990; governs incorporation and regulation of companies

Constitution of Nigeria	1999 (amended)	Supreme law; Section 37 guarantees the right to private and family life

Deployment Tier

SMALL/MEDIUM -- Likely single tier bundled, possibly dual tier if the full corpus (including state legislation) exceeds npm package size limits.

Estimated database size: ~100-250 MB (federal Acts, regulations, and selected state 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 Nigerian 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 Nigerian statute
get_nigerian_implementations	Find Nigerian laws implementing EU act
search_eu_implementations	Search EU documents with Nigerian 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 Nigerian 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 Nigerian legal databases:

• National Assembly -- Official Nigerian government legal database

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

Security

Important Disclaimers

Legal Advice

THIS TOOL IS NOT LEGAL ADVICE

Statute text is sourced from official Nigerian 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.
