Description: Azure DevOps reference server for the Model Context Protocol (MCP)
Latest version: 0.1.1

# Azure DevOps MCP Server

A Model Context Protocol (MCP) server implementation for Azure DevOps, allowing AI assistants to interact with Azure DevOps APIs through a standardized protocol.

## Overview

This server implements the [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) for Azure DevOps, enabling AI assistants like Claude to interact with Azure DevOps resources securely. The server acts as a bridge between AI models and Azure DevOps APIs, providing a standardized way to:

- Access and manage projects, work items, repositories, and more
- Create and update work items, branches, and pull requests
- Execute common DevOps workflows through natural language
- Access repository content via standardized resource URIs
- Safely authenticate and interact with Azure DevOps resources

## Server Structure

The server is structured around the Model Context Protocol (MCP) for communicating with AI assistants. It provides tools for interacting with Azure DevOps resources including:

- Projects
- Work Items
- Repositories
- Pull Requests
- Branches
- Pipelines

### Core Components

- **AzureDevOpsServer**: Main server class that initializes the MCP server and registers tools
- **Feature Modules**: Organized by feature area (work-items, projects, repositories, etc.)
- **Request Handlers**: Each feature module provides request identification and handling functions
- **Tool Handlers**: Modular functions for each Azure DevOps operation
- **Configuration**: Environment-based configuration for organization URL, PAT, etc.

The server uses a feature-based architecture where each feature area (like work-items, projects, repositories) is encapsulated in its own module. This makes the codebase more maintainable and easier to extend with new features.

## Getting Started

### Prerequisites

- Node.js (v16+)
- npm or yarn
- Azure DevOps account with appropriate access
- Authentication credentials (see [Authentication Guide](docs/authentication.md) for details):
  - Personal Access Token (PAT), or
  - Azure Identity credentials, or
  - Azure CLI login

### Running with NPX

### Usage with Claude Desktop/Cursor AI

To integrate with Claude Desktop or Cursor AI, add one of the following configurations to your configuration file.

#### Azure Identity Authentication

Be sure you are logged in to Azure CLI with `az login` then add the following:

```json
{
  "mcpServers": {
    "azureDevOps": {
      "command": "npx",
      "args": ["-y", "@nvhien20vn/mcp-az-devops"],
      "env": {
        "AZURE_DEVOPS_ORG_URL": "https://dev.azure.com/your-organization",
        "AZURE_DEVOPS_AUTH_METHOD": "azure-identity",
        "AZURE_DEVOPS_DEFAULT_PROJECT": "your-project-name"
      }
    }
  }
}
```

#### Personal Access Token (PAT) Authentication

```json
{
  "mcpServers": {
    "azureDevOps": {
      "command": "npx",
      "args": ["-y", "@nvhien20vn/mcp-az-devops"],
      "env": {
        "AZURE_DEVOPS_ORG_URL": "https://dev.azure.com/your-organization",
        "AZURE_DEVOPS_AUTH_METHOD": "pat",
        "AZURE_DEVOPS_PAT": "<YOUR_PAT>",
        "AZURE_DEVOPS_DEFAULT_PROJECT": "your-project-name"
      }
    }
  }
}
```

For detailed configuration instructions and more authentication options, see the [Authentication Guide](docs/authentication.md).

## Authentication Methods

This server supports multiple authentication methods for connecting to Azure DevOps APIs. For detailed setup instructions, configuration examples, and troubleshooting tips, see the [Authentication Guide](docs/authentication.md).

### Supported Authentication Methods

1. **Personal Access Token (PAT)** - Simple token-based authentication
2. **Azure Identity (DefaultAzureCredential)** - Flexible authentication using the Azure Identity SDK
3. **Azure CLI** - Authentication using your Azure CLI login

Example configuration files for each authentication method are available in the [examples directory](docs/examples/).
