🚀 Getting Started with Installation

Phase 1: Setting Up the MCP Server

1. Clone this repository

   git clone https://github.com/JBAgent/Test1.git
   cd Test1
   

2. Install dependencies for the MCP server

   cd mcp-server
   npm install
   

3. Configure environment variables

   cp .env.example .env
   # Edit .env with your Azure AD credentials
   

4. Start the MCP server

   npm start
   

5. Test the MCP server

   • Using the provided test client:

     node test-client.js
     

   • Alternatively using curl:

     curl -X POST http://localhost:3000/api/graph \
       -H "Content-Type: application/json" \
       -H "X-User-ID: default-user" \
       -d '{"endpoint": "/users", "method": "GET", "queryParams": {"$top": 5}, "allData": false}'
     

Phase 2: Setting Up the Claude Integration

1. Install dependencies for the Claude application

   cd ../claude-app
   npm install
   

2. Configure environment variables

   cp .env.example .env
   # Edit .env with your Anthropic API key and MCP server URL
   

3. Start the Claude application

   npm start
   

4. Test the Claude integration

   curl -X POST http://localhost:4000/api/chat \
     -H "Content-Type: application/json" \
     -d '{"messages": [{"role": "user", "content": "How many users are in our organization?"}]}'
   

💡 Key Use Cases in AI Workflows

1. Organizational Analysis
   Users can ask Claude questions about their company's structure and membership, such as identifying key personnel or counting the number of employees in a department.

2. Personalized Recommendations
   The AI application can provide personalized insights based on user data retrieved from Microsoft Graph, enhancing user experience through tailored suggestions and information.

🔌 Integration with MCP Clients

Claude integration relies on an MCP client to manage connections and requests between the AI application and the underlying server. The following configuration ensures compatibility:

{
  "mcpServers": {
    "[server-name]": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-[name]"],
      "env": {
        "API_KEY": "your-api-key"
      }
    }
  }
}

🛠️ Advanced Configuration & Security

Customizing the Integration

• Adding More Graph API Functions
  Edit claude-mcp-integration.js to add specialized functions and update function definitions in claude-app.js.

• Implementing Caching (Optional)
  Add Redis for caching common Graph API responses, and update the MCP server to check cache before making API calls.

Security Considerations

1. Authentication
   • MCP server uses Azure AD authentication.
2. Authorization
   • Enforce permissions based on user context.
3. Data Protection
   • Be mindful of data shared with Claude.
4. Audit Logging
   • Log all Graph API requests for compliance.

❓ Frequently Asked Questions (FAQ)

1. I’m getting a rate limit error, what can I do?
   You may need to implement caching mechanisms or throttle request frequency to avoid hitting the rate limits set by Microsoft Graph and your MCP server.

2. How do I customize functions in the server?
   Modify claude-mcp-integration.js to add new functions that meet specific requirements, ensuring they are compatible with the AI application's needs.

3. What is the performance impact of adding Redis caching?
   Caching can significantly reduce response times and API request rates, enhancing overall system performance without affecting user experience negatively.

4. Is my data safe when using this server?
   The server uses Azure AD for authentication, ensuring secure access to resources. Additionally, implementing robust data handling practices further protects sensitive information.

5. How can I integrate other tools with the MCP server?
