MCP Server Integration

The Claude Code Development Kit enhances AI reliability by integrating with external MCP (Model Context Protocol) servers. This approach follows a "four eyes principle," where Claude Code can consult specialized external services to cross-validate its work, fetch up-to-the-minute information, and get a second opinion on complex architectural problems.

What is MCP?

MCP is a standard protocol that allows Claude Code to communicate with external AI services. The kit is pre-configured to integrate with two highly recommended MCP servers.

Integrated MCP Servers

Service Purpose Benefit
Context7 Real-time library docs Provides current APIs, not outdated training data.
Gemini Assistant Architectural consultation Offers cross-validation and best practices.

Context7: Real-Time Library Documentation

Problem: LLMs are trained on data that can be months or years old. This means they often hallucinate API methods or use deprecated patterns for libraries that have been updated.

Solution: The Context7 MCP server provides a live, up-to-date documentation source for thousands of popular libraries. When a command needs to work with a library like FastAPI or React, it can query Context7 to ensure it's using the latest, correct APIs.

Gemini Assistant: Architectural Consultation

Problem: A single AI model can sometimes get stuck on a particular approach or fail to see a better architectural pattern.

Solution: The Gemini Assistant MCP server acts as an expert consultant. Commands like /code-review or /full-context can call on Gemini to get a second opinion on a proposed implementation, ask for alternative architectural patterns, or review code for subtle flaws.

The kit's hooks automatically inject your project's structure (project-structure.md) and coding standards (MCP-ASSISTANT-RULES.md) into every Gemini consultation, ensuring the advice is tailored to your specific project.

How to Use MCP Servers

During the installation, you can choose to include integrations for these servers. If you do, commands will automatically leverage them where appropriate.

  • The /gemini-consult command is dedicated to interacting with the Gemini Assistant.
  • Other commands, like /code-review, will use MCP servers in the background as part of their analysis process.

You will need to install and run the MCP servers separately. The setup script provides links and instructions for this.
