How to Set Up and Use Mentor MCP
Mentor MCP Server gives LLM agents a second opinion by routing review requests through DeepSeek's Reasoning R1 model, a chain-of-thought reasoner that is particularly strong at structured critique. It exposes four tools — code review, design critique, writing feedback, and idea brainstorming — so agents or developers can request expert-level analysis on any artifact without leaving their current AI environment. The server acts as a reasoning layer on top of the primary model, catching issues that generalist LLMs tend to miss in security, architectural coherence, and documentation clarity.
Prerequisites
- Node.js 18 or higher installed
- A DeepSeek API key (sign up at platform.deepseek.com)
- An MCP-compatible client such as Claude Desktop, Claude Code, or Cursor
- npm or git available to install from source
Clone the repository
Mentor MCP Server is installed from source. Clone the repository and enter the project directory.
git clone https://github.com/cyanheads/mentor-mcp-server.git
cd mentor-mcp-serverInstall dependencies and build
Install npm dependencies and compile the TypeScript source.
npm install && npm run buildSet required environment variables
Export your DeepSeek API key and optionally set the model and token limits. DEEPSEEK_API_KEY is required; the model defaults to deepseek-reasoner.
export DEEPSEEK_API_KEY=your_deepseek_api_key_here
export DEEPSEEK_MODEL=deepseek-reasoner
export DEEPSEEK_MAX_TOKENS=8192Configure your MCP client
Add the mentor server to your MCP client configuration, passing the API key as an environment variable.
Test the server
Ask your AI assistant to review a code snippet. The request will be routed through DeepSeek R1 and a structured critique will be returned.
Mentor MCP Examples
Client configuration
Add Mentor MCP Server to claude_desktop_config.json with your DeepSeek API key passed as an environment variable.

}Prompts to try
Use these prompts to get deep, reasoning-model-powered reviews of code, designs, writing, and ideas.
- "Review this TypeScript authentication module for security vulnerabilities and code quality"
- "Critique this REST API design for consistency and scalability issues"
- "Give feedback on this technical documentation for clarity and completeness"
- "Brainstorm enhancements for a user authentication system that currently only supports email/password"
- "Review this React dashboard component for accessibility and performance problems"Troubleshooting Mentor MCP
Requests fail with a 401 Unauthorized error from DeepSeek
Verify that DEEPSEEK_API_KEY is set correctly in the MCP client's env block. Keys from platform.deepseek.com must be active and have sufficient credits. Test independently with: curl -H 'Authorization: Bearer YOUR_KEY' https://api.deepseek.com/models
Responses time out on long code reviews
Increase the DEEPSEEK_TIMEOUT environment variable (default is 30000ms). For large files, set it to 120000 or higher: export DEEPSEEK_TIMEOUT=120000
The build step fails with TypeScript errors
Ensure you are using Node.js 18 or higher. Run 'node --version' to check. Delete node_modules and package-lock.json, then re-run 'npm install && npm run build'.
