LegalMCP - Indian Legal Research Assistant

An MCP (Model Context Protocol) server that provides intelligent legal research tools for Indian law practitioners, leveraging the IndianKanoon API to automate citation work and case law research.

🎯 Overview

LegalMCP transforms legal research from hours of manual work to minutes of automated analysis. It provides five specialized tools that work together to search precedents, extract legal principles, build research memos, format citations, and verify citation accuracy.

Key Benefits

• Reduce research time from 3-4 hours to 30 minutes
• Eliminate citation errors with automated formatting
• Comprehensive coverage with intelligent search strategies
• Professional output with properly structured legal memos

🛠️ Tools

1. search_legal_precedents

Search IndianKanoon for relevant cases with intelligent ranking based on:

• Court hierarchy (Supreme Court > High Courts)
• Recency and citation metrics
• Multiple search variants for comprehensive coverage

2. extract_legal_principles

Extract specific legal principles from cases with:

• Pinpoint paragraph-level citations
• Context windows around key principles
• Distinction between ratio decidendi and obiter dicta

3. build_case_compilation

Create comprehensive legal research memos featuring:

• Multi-stage search strategy
• Automatic organization by legal principles
• Professional memo structure with citations

4. format_citations

Generate properly formatted citations in Indian legal styles:

• AIR, SCC, Neutral, and SCC OnLine formats
• Parallel citation discovery
• Multiple output formats (full, short, footnote, bibliography)

5. verify_citations

Validate and correct citations with:

• Accuracy verification against IndianKanoon database
• Error detection and correction suggestions
• Cross-reference validation

🚀 Installation

Prerequisites

• Node.js 18+
• npm or yarn
• IndianKanoon API key

Setup

1. Clone the repository:

git clone https://github.com/Stoops0311/LegalMCP.git
cd LegalMCP

2. Install dependencies:

npm install

3. Configure your API key (see Configuration section)

4. Start development server:

npm run dev

⚙️ Configuration

The server requires an IndianKanoon API key. Configuration can be provided via:

Option 1: Environment Variables

export INDIANKANOON_API_KEY="your-api-key-here"

Option 2: Session Configuration

When using with Smithery or MCP clients, provide configuration:

{
  "indianKanoonApiKey": "your-api-key",
  "defaultCourt": "supremecourt",
  "maxSearchResults": 20,
  "citationStyle": "SCC OnLine",
  "enableCaching": true,
  "cacheTimeout": 60
}

Configuration Options

Option	Type	Description	Default
indianKanoonApiKey	string	Required - Your IndianKanoon API key	-
defaultCourt	string	Preferred court for searches	"supremecourt"
maxSearchResults	number	Maximum search results (10-100)	20
citationStyle	string	Default citation format	"SCC OnLine"
enableCaching	boolean	Cache search results	true
cacheTimeout	number	Cache timeout in minutes	60

📖 Usage Examples

Basic Search

// Search for trademark infringement cases
await search_legal_precedents({
  query: "trademark infringement",
  court: "delhi",
  dateRange: { from: "2015", to: "2024" }
})

Extract Legal Principles

// Extract principles about consumer confusion
await extract_legal_principles({
  documentId: "178980348",
  searchTerms: ["consumer confusion", "deceptive similarity"]
})

Build Research Memo

// Create comprehensive research on a legal issue
await build_case_compilation({
  issue: "Criminal defamation under Section 499 IPC",
  subIssues: ["public interest defense", "truth as justification"],
  jurisdiction: ["supremecourt", "delhi"]
})
