Quick Start

Install

We recommend using a virtual environment to avoid conflicts with other packages:

# Create and activate a virtual environment
python -m venv legal-mcp-env

# Windows
legal-mcp-env\Scripts\activate

# Mac/Linux
source legal-mcp-env/bin/activate

# Install
pip install legal-mcp

Or install from GitHub:

pip install git+https://github.com/Mahender22/legal-mcp.git

Run

Want to try it without API keys? Enable demo mode first (optional):

# Mac/Linux
export LEGAL_MCP_DEMO=true

# Windows
set LEGAL_MCP_DEMO=true

Then start the server:

legal-mcp

Connect to Claude Desktop

Add to your claude_desktop_config.json:

Windows (%APPDATA%\Claude\claude_desktop_config.json):

{
  "mcpServers": {
    "legal-mcp": {
      "command": "C:/path/to/legal-mcp-env/Scripts/legal-mcp.exe",
      "env": {
        "LEGAL_MCP_DEMO": "true"
      }
    }
  }
}

Mac/Linux (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "legal-mcp": {
      "command": "/path/to/legal-mcp-env/bin/legal-mcp",
      "env": {
        "LEGAL_MCP_DEMO": "true"
      }
    }
  }
}

Note: Use the full path to legal-mcp inside your virtual environment. Remove the LEGAL_MCP_DEMO line and add your API keys for real data (see SETUP.md).

Connect to Claude Code

Run this command to add LegalMCP globally (available in every session):

Mac/Linux:

claude mcp add legal-mcp /path/to/legal-mcp-env/bin/legal-mcp

Windows:

claude mcp add legal-mcp C:\path\to\legal-mcp-env\Scripts\legal-mcp.exe

To enable demo mode, add the env flag:

Mac/Linux:

claude mcp add legal-mcp -e LEGAL_MCP_DEMO=true -- /path/to/legal-mcp-env/bin/legal-mcp

Windows:

claude mcp add legal-mcp -e LEGAL_MCP_DEMO=true -- C:\path\to\legal-mcp-env\Scripts\legal-mcp.exe

Tip: To add it to a specific project only, add -s project flag or create a .mcp.json file in your project root.

Connect to Cursor / Windsurf

LegalMCP works with any MCP-compatible client. Add the legal-mcp command to your AI tool's MCP server configuration.

This starts the MCP server on port 8000 and the waitlist API on port 8080.

How It Works

LegalMCP is a Model Context Protocol server. MCP is an open standard that lets AI assistants call external tools — like searching case law or querying your Clio data.

┌──────────────┐     MCP      ┌──────────────┐      API      ┌──────────────┐

└──────────────┘               └──────────────┘               └──────────────┘

Your data stays on your machine. LegalMCP runs locally and connects directly to the APIs.
