ado-mcp-raboley 0.0.1

An MCP server for Azure DevOps pipelines.

ADO MCP

This project uses FastMCP 2.0 python sdk to interact with Azure DevOps.

Setup

1. Install Dependencies:

   task install
   

2. Set up Authentication: The MCP server supports multiple authentication methods (in order of precedence):

   Option 1: Personal Access Token (PAT)

   Environment Variable Method:

   task setup-env
   

   This creates a .env file with your Personal Access Token (PAT) and other necessary variables.

   Direct Configuration:

   export AZURE_DEVOPS_EXT_PAT="your-personal-access-token"
   export ADO_ORGANIZATION_URL="https://dev.azure.com/YourOrg"
   

   Option 2: Azure CLI Authentication (Recommended)

   If you already use Azure CLI, you can authenticate using your existing session:

   # Login to Azure (if not already logged in)
   az login
   
   # The MCP server will automatically use your Azure CLI credentials
   task run
   

   Benefits of Azure CLI authentication:

   • No need to manage Personal Access Tokens
   • Uses your existing Azure credentials
   • More secure than storing PATs
   • Automatically refreshes tokens

   Note: Azure CLI authentication requires the user to be logged in with an account that has access to the Azure DevOps organization.

Testing

• Run Tests:

  task test
  

• Test Coverage:

  task coverage
  

Usage

• Run the MCP Server:

  task run
  

• Inspect the MCP Server:

  task inspect
  

Working with Azure DevOps URLs

Understanding Azure DevOps URL Structure

When working with Azure DevOps URLs from the web interface, it's important to understand the difference between build/run IDs and pipeline definition IDs:

Example URL: https://dev.azure.com/RussellBoley/ado-mcp/_build/results?buildId=324&view=results

• Organization: RussellBoley (from the URL path)
• Project: ado-mcp (from the URL path)
• buildId=324: This is a run ID (specific execution instance), NOT a pipeline definition ID

Getting Pipeline Information from Build URLs

To work with a specific build/run from an Azure DevOps URL:

1. Extract URL components:

   • Organization: RussellBoley
   • Project: ado-mcp
   • Build/Run ID: 324 (from buildId parameter)

2. Use get_build_by_id to find the pipeline:

   # Get build details to find the pipeline definition
   build_details = await client.call_tool("get_build_by_id", {
       "project_id": "49e895da-15c6-4211-97df-65c547a59c22",  # ado-mcp project ID
       "build_id": 324  # The buildId from the URL
   })
   
   # Extract pipeline information
   pipeline_id = build_details.data["definition"]["id"]        # e.g., 84
   pipeline_name = build_details.data["definition"]["name"]    # e.g., "log-test-complex"
   

3. Then use pipeline-specific tools:

   # Get detailed run information
   run_details = await client.call_tool("get_pipeline_run", {
       "project_id": "49e895da-15c6-4211-97df-65c547a59c22",
       "pipeline_id": pipeline_id,  # 84
       "run_id": 324               # Same as buildId
   })
   
   # Get failure analysis if needed
   failure_summary = await client.call_tool("get_pipeline_failure_summary", {
       "project_id": "49e895da-15c6-4211-97df-65c547a59c22",
       "pipeline_id": pipeline_id,
       "run_id": 324
   })
   

Common Mistake to Avoid

❌ Don't do this:

# This will fail - you can't guess the pipeline_id
await client.call_tool("get_pipeline_run", {
    "project_id": "49e895da-15c6-4211-97df-65c547a59c22",
    "pipeline_id": 15,  # Wrong! This is just a guess
    "run_id": 324
})

✅ Do this instead:

# First, get the build details to find the correct pipeline_id
build_data = await client.call_tool("get_build_by_id", {
    "project_id": "49e895da-15c6-4211-97df-65c547a59c22",
    "build_id": 324  # buildId from URL
})

pipeline_id = build_data.data["definition"]["id"]  # Now you have the correct pipeline_id

# Then use it for pipeline-specific operations
await client.call_tool("get_pipeline_run", {
    "project_id": "49e895da-15c6-4211-97df-65c547a59c22", 
    "pipeline_id": pipeline_id,  # Correct pipeline_id
    "run_id": 324
})

Available Tools for Build/Pipeline Analysis

• get_build_by_id: Get build details and extract pipeline information from a build/run ID
• get_pipeline_run: Get detailed run information (requires both pipeline_id and run_id)
• get_pipeline_failure_summary: Analyze failures with root cause analysis
• get_failed_step_logs: Get logs for failed steps
• get_pipeline_timeline: Get execution timeline
• list_pipeline_logs: List all available logs
• get_log_content_by_id: Get specific log content
• run_pipeline_and_get_outcome: Run a pipeline and wait for completion with analysis
