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) 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 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:

{
  "mcpServers": {
    "azureDevOps": {
      "command": "npx",
      "args": ["-y", "@tiberriver256/mcp-server-azure-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

{
  "mcpServers": {
    "azureDevOps": {
      "command": "npx",
      "args": ["-y", "@tiberriver256/mcp-server-azure-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.

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.

Supported Authentication Methods

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

Example configuration files for each authentication method are available in the examples directory.
