How to Set Up and Use Cerebra Legal
The Cerebra Legal MCP Server is an enterprise-grade TypeScript server that extends AI assistants with structured legal reasoning tools, automatically detecting the relevant legal domain from context and providing domain-specific templates, citation formatting, and guided analysis. It exposes three specialized MCP tools — legal_think, legal_ask_followup_question, and legal_attempt_completion — that model a rigorous legal reasoning workflow from issue spotting through conclusion. Designed for legal professionals and enterprises, it supports domains like consumer protection, contract analysis, and administrative contestation.
Prerequisites
- Node.js (LTS version recommended) and npm installed
- Git to clone the repository
- An MCP client such as Claude Desktop, VS Code with Roo-Cline extension, or any MCP-compatible host
- Basic familiarity with JSON configuration files for your chosen MCP client
Clone the repository

git clone https://github.com/yoda-digital/mcp-cerebra-legal-server.git
cd mcp-cerebra-legal-serverInstall dependencies
Install all required Node.js packages using npm.
npm installBuild the server
Compile the TypeScript source into JavaScript. The build output will be placed in the 'build' directory.
npm run buildConfigure your MCP client
Add the server to your MCP client configuration. For Claude Desktop on macOS, edit ~/Library/Application Support/Claude/claude_desktop_config.json. Replace /path/to with the actual path where you cloned the repository.
{
"mcpServers": {
"cerebra-legal": {
"command": "node",
"args": ["/path/to/mcp-cerebra-legal-server/build/index.js"],
"disabled": false,
"alwaysAllow": []
}
}
}Verify the server with the test client
Run the included test client to confirm the server is working correctly before using it through your MCP host.
chmod +x test-client.js
./test-client.jsCerebra Legal Examples
Client configuration

}
}
}Prompts to try
Example prompts that exercise the legal reasoning, follow-up questioning, and completion tools.
- "Analyze this contract clause for potential consumer protection issues under EU law"
- "Draft a formal contestation letter for an administrative decision regarding my business license"
- "What are the key elements I need to establish for a breach of contract claim?"
- "Format the following case citations in Bluebook style: [paste citations]"
- "Walk me through the legal analysis of this GDPR data processing scenario"Troubleshooting Cerebra Legal
Server fails to start with 'Cannot find module' errors
Ensure you ran 'npm run build' after 'npm install'. The build step compiles TypeScript to JavaScript in the build/ directory. If the error persists, delete node_modules and run 'npm install' again.
MCP client cannot connect to the server
Verify the absolute path in args points to build/index.js, not src/index.ts. Also confirm Node.js is in your system PATH by running 'which node' in your terminal.
Legal domain detection is not recognizing the correct domain
Provide more explicit context in your prompt about the legal jurisdiction and domain (e.g., 'Under EU consumer protection law...' or 'In the context of US contract law...'). The server uses the content of your request to determine which domain-specific templates and guidance to apply.
