Norwegian Law MCP Server

Production-grade MCP server for Norwegian legal research with licensing-aware ingestion controls.

What this server provides

• Search and retrieval tools for legal documents/provisions
• EU cross-reference tooling
• Deterministic SQLite build pipeline
• Capability detection via DB schema
• Daily data freshness monitor with optional auto-PR
• Security and publishing workflows (CodeQL, Semgrep, Trivy, Gitleaks, Socket, Scorecard, provenance publish)

Hard architecture parity (implemented)

• build:db is destructive and rebuilds from seed files
• build:db:paid is additive and upgrades schema/tier metadata
• db_metadata table is written and read for runtime capability detection
• Database artifacts are gitignored (data/*.db, *.db-wal, *.db-shm)
• server.json present and aligned with package.json mcpName

Country-specific ingestion and legal-risk control

Official-source direction for Norway is configured with a licensing gate.

• Ingestion script: scripts/ingest-lovdata.ts
• License gate module: scripts/lib/legal-data-license.ts
• Policy seed: data/seed/_legal_data_license.json
• Policy doc: LEGAL_DATA_LICENSE.md

Default policy mode is full-text for covered statutes/regulations and metadata-only for restricted sources (for example case-law channels without explicit rights).

Install

npm ci
npm run build:db
npm run build
npm test

Run

npm start

Key scripts

• npm run build:db - destructive free-tier DB rebuild from seeds
• npm run build:db:paid - additive professional-tier schema upgrade
• npm run ingest -- <LOV-ID> <output-file> - license-gated Norwegian ingestion
• npm run ingest:all - ingest full official NL+NLO statute catalog from data/relevant-statutes-all.json
• npm run ingest:auto-all - default full-catalog ingestion entrypoint (same dataset as ingest:all)
• npm run check-updates - official-source freshness check

Validation commands

npm ci

npm run build
npm test
npm run check-updates
gitleaks detect --source . --report-format sarif --report-path gitleaks.sarif --no-git
