नेपाल कानून आयोगबाट प्रकाशित ३२८ वटा ऐनहरू र ३,४२४ वटा धाराहरू खोज्न मिल्ने tool।

An MCP (Model Context Protocol) server with a web interface that provides search access to Nepali statutes scraped from lawcommission.gov.np. Includes a full PDF parsing pipeline with OCR fallback for section-level text extraction.

Features

• search_statute: Full-text search across all statute titles and provisions using SQLite FTS5 + LIKE fallback
• get_provision: Retrieve the full text of a specific section by act name and section number
• list_acts: List all 328 acts in the database with Nepali/English titles, year, and status
• check_status: Check whether an act is in force or repealed, with text quality and provision count
• Web interface: Nepali-language SPA at http://localhost:3001 with search (debounced), browse, and provision viewer
• PDF pipeline: Download PDFs from CDN, extract sections via pdfjs-dist + tesseract OCR, quality-check

Setup

# Install dependencies
npm install

# Build TypeScript
npm run build

Ingest Data

# Ingest all acts from the alphabetical index
npm run ingest

# Ingest a single act by name
npm run ingest -- --single "अख्तियार"

Parse PDFs (extract section-level text)

# Process acts with PDF URLs (default: 5)
npm run parse-pdfs

# Process more acts
MAX_ACTS=100 npm run parse-pdfs

# Retry only previously-failed acts
FAILED_ONLY=1 npm run parse-pdfs

# Enable OCR-based title validation
OCR_TITLE_VALIDATE=1 npm run parse-pdfs

Web Interface

# Start the web server on port 3001
npm run web

# Or development mode (hot-reload)
npm run web:dev

Open http://localhost:3001 to search and browse all acts.
