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 from npm (npx)

If you just want to run the published server package, you do not need to clone or build this repository:

npx -y @tiberriver256/mcp-server-azure-devops

Running locally (from source)

From a checkout of this repository:

npm ci
cp .env.example .env   # then edit values
npm run build
npm start              # runs: node dist/index.js

For iterative development (auto-reload):

npm run dev            # runs src/index.ts via ts-node-dev

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"
      }
    }
  }
}

Azure DevOps Server (on-prem) requires PAT authentication. Example:

{
  "mcpServers": {
    "azureDevOps": {
      "command": "npx",
      "args": ["-y", "@tiberriver256/mcp-server-azure-devops"],
      "env": {
        "AZURE_DEVOPS_ORG_URL": "https://server:8080/tfs/DefaultCollection",
        "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

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.

Azure DevOps Server (on-prem) supports PAT authentication only. Azure Identity and Azure CLI are supported for Azure DevOps Services.

Environment Variables

Key environment variables include:

| Variable | Description | Required | Default | | ------------------------------ | ---------------------------------------------------------------------------------- | ---------------------------- | ---------------- | | AZURE_DEVOPS_AUTH_METHOD | Authentication method (pat, azure-identity, or azure-cli) - case-insensitive | No | azure-identity | | AZURE_DEVOPS_ORG_URL | Full URL to your Azure DevOps organization or Server collection (e.g., https://server:8080/tfs/DefaultCollection) | Yes | - | | AZURE_DEVOPS_PAT | Personal Access Token (for PAT auth) | Only with PAT auth | - | | AZURE_DEVOPS_DEFAULT_PROJECT | Default project if none specified | No | - | | AZURE_DEVOPS_API_VERSION | API version to use | No | Latest | | AZURE_TENANT_ID | Azure AD tenant ID (for service principals) | Only with service principals | - | | AZURE_CLIENT_ID | Azure AD application ID (for service principals) | Only with service principals | - | | AZURE_CLIENT_SECRET | Azure AD client secret (for service principals) | Only with service principals | - | | LOG_LEVEL | Logging level (debug, info, warn, error) | No | info |
