About mentor-mcp-server
mentor-mcp-server is an MCP server that gives LLM agents a second opinion by calling the Deepseek-Reasoner (R1) model through the Deepseek API. It targets developers and agents that need code review, design critique, writing feedback or brainstorming.
Key features
- 01Code review with security and performance suggestions
- 02UI/UX and architecture design critique
- 03Writing and documentation feedback
- 04Feature enhancement brainstorming
- 05Configurable model, token limit, retries and timeout
Use cases
- 01Having an agent review a TypeScript file before commit
- 02Requesting a second opinion on a UI or architecture design
- 03Improving the structure and clarity of technical documentation
MCP support
This project is an MCP server that provides tools such as code_review, design_critique, writing_feedback and brainstorm_enhancements to MCP clients.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.
Details
From the project READMEmentor-mcp-server
A Model Context Protocol server providing LLM Agents a second opinion via AI-powered Deepseek-Reasoning (R1) mentorship capabilities, including code review, design critique, writing feedback, and idea brainstorming through the Deepseek API. Set your LLM Agent up for success with expert second opinions and actionable insights.
Model Context Protocol
The Model Context Protocol (MCP) enables communication between:
- Clients: Claude Desktop, IDEs, and other MCP-compatible clients
- Servers: Tools and resources for task management and automation
- LLM Agents: AI models that leverage the server's capabilities

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
