Second Opinion MCP Server: Enhancing AI Application Integration through Model Context Protocol

Overview: What is Second Opinion MCP Server?

The Second Opinion MCP Server is an advanced AI-powered assistant designed to provide detailed solutions for coding problems by leveraging multiple cutting-edge tools and platforms. By combining insights from Google's Gemini AI, Stack Overflow accepted answers, and Perplexity AI analysis, it offers comprehensive support that goes beyond traditional debugging tools.

🔧 Core Features & MCP Capabilities

The Second Opinion MCP Server features a robust set of capabilities driven by Model Context Protocol (MCP). This protocol is designed to standardize the interaction between AI applications and various data sources or tools. Here are some key functionalities:

Multi-source Insight Integration: It combines real-time insights from Gemini, Perplexity AI, and curated Stack Overflow resources.
Automatic Language Detection & Code Snippet Formatting: The server automatically detects the programming language of your files and formats code snippets for better readability and integration.
Markdown Report Generation: It generates Markdown documents that detail potential solutions to coding problems, offering a structured and user-friendly format.
Git-Aware File Context Gathering: The server gathers relevant context from Git repositories, ensuring you have all necessary background information before suggesting solutions.

⚙️ MCP Architecture & Protocol Implementation

The Second Opinion MCP Server is built upon Model Context Protocol (MCP), which is designed to enable seamless integration between AI applications and diverse data sources. Here’s how the protocol is implemented:

Command Execution: The server runs specific commands that invoke AI services or interact with code repositories.
Environment Configuration: It requires environment variables such as API keys for external services, ensuring secure and consistent access to these resources.

🚀 Getting Started with Installation

To set up the Second Opinion MCP Server, follow these steps:

Install Dependencies
```
npm install
```
Build the Server
```
npm run build
```

Configure Environment Variables

Save your environment variables in a MCP settings file or directly within the configuration as follows:

{
  "mcpServers": {
    "second-opinion": {
      "command": "node",
      "args": ["/path/to/second-opinion-server/build/index.js"],
      "env": {
        "GEMINI_API_KEY": "your-gemini-api-key",
        "PERPLEXITY_API_KEY": "your-perplexity-api-key",
        "STACK_EXCHANGE_KEY": "your-stack-exchange-key"
      }
    }
  }
}

💡 Key Use Cases in AI Workflows

This MCP Server shines in several key areas, enhancing the development workflow for AI applications:

Problem Debugging: Gain insights into complex code issues and receive detailed solutions to resolve them.
Code Quality Improvement: Use integrated tools to detect potential coding errors and improve overall code quality.

Real-world Implementation Example: Code Debugging

Consider a scenario where a developer is encountering an issue with React components. By integrating the Second Opinion MCP Server, they can input their problem description into the server, which then retrieves insights from multiple sources. The server might identify that the useEffect hook has a missing dependency issue, thereby providing a detailed solution.

Real-world Implementation Example: Code Quality Review

In another use case, a developer wants to improve the quality of their codebase. They can submit a code snippet to the MCP Server, which then provides feedback based on multiple analysis tools. This helps ensure that the code adheres to best practices and is free from common coding mistakes.

🔌 Integration with MCP Clients

The Second Opinion MCP Server is compatible with several prominent AI applications and tools:

MCP Client	Resources	Tools	Prompts	Status
Claude Desktop	✅	✅	✅	Full Support
Continue	✅	✅	✅	Full Support
