yoda-digital/mcp-cerebra-legal-server

An enterprise-grade MCP server for legal reasoning and analysis based on the "think" tool concept from Anthropic's engineering blog.
## Overview
Cerebra Legal provides three powerful tools for legal reasoning and analysis:
1. legal_think - A structured legal reasoning tool that helps analyze complex legal issues with domain-specific guidance and templates.
2. legal_ask_followup_question - A specialized tool for asking follow-up questions in legal contexts with domain-specific options.
3. legal_attempt_completion - A tool for presenting legal analysis results with proper structure and citation formatting.
The server automatically detects legal domains (ANSC contestation, consumer protection, contract analysis) and provides domain-specific guidance, templates, and feedback.
## Features
Domain Detection: Automatically identifies the legal domain of the analysis
Domain-Specific Guidance: Provides tailored guidance for different legal domains
Structured Templates: Offers domain-specific templates for legal analysis
Citation Formatting: Properly formats legal citations
Thought Quality Analysis: Provides feedback on legal reasoning quality
Revision Support: Allows for revising previous thoughts
## Installation
bash
# Clone the repository
git clone https://github.com/yoda-digital/mcp-cerebra-legal-server.git
cd mcp-cerebra-legal-server
# Install dependencies
npm install
# Build the project
npm run build
## Usage
### Running the Server
bash
npm start
### Testing the Server
The repository includes a test client that demonstrates how to interact with the server:
bash
# Make the test client executable
chmod +x test-client.js
# Run the test client
./test-client.js
The test client will:
1. Start the server
2. Send a tools/list request to get available tools
3. Send a legal_think request with a sample thought
4. Display the server's responses
### Adding to Claude
To add the server to Claude, update your MCP settings file with the following configuration:
#### For VSCode Extension
Edit the file at ~/.config/Code/User/globalStorage/rooveterinaryinc.roo-cline/settings/cline_mcp_settings.json:
json
"mcpServers": {
"cerebra-legal": {
"command": "node",
"args": ["/path/to/mcp-cerebra-legal-server/build/index.js"],
"disabled": false,
"alwaysAllow": []
#### For Claude Desktop App
Edit the file at ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or the equivalent on your platform:
json
"mcpServers": {
"cerebra-legal": {
"command": "node",
"args": ["/path/to/mcp-cerebra-legal-server/build/index.js"],
"disabled": false,
"alwaysAllow": []
### Using the Tools in Claude
Once the server is added to Claude, you can use the tools in your conversations:
### System Prompt Integration
For optimal AI interaction with these legal tools, it's essential to include proper guidance in the system prompt. These tools follow the same AI → Human interaction model as standard Cline tools but with domain-specific enhancements.
The system prompt should include detailed documentation for each tool:
## legal_think
Description: A structured legal reasoning tool that helps analyze complex legal issues with domain-specific guidance and templates. This tool enables step-by-step legal analysis with feedback on reasoning quality.
