mentor-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
