requirements

• MCP proxy installed. See Setup MCP proxy for STDIO MCP servers for more details.

Create and setup a Personal Access Token (PAT)

Before you integrate with the Azure DevOps MCP server, you need a Personal Access Token (PAT) to authenticate with Azure DevOps. Follow these steps:

1. Go to Azure DevOps: <https://dev.azure.com/{YourOrganization}>
2. Click on User Settings (top right) > Personal Access Tokens.

3. Click + New Token.
4. Configure:
   • Name: Give it a descriptive name (e.g., "MCP Bridge")
   • Organization: Select your organization (e.g., "Katalon")
   • Expiration: Set expiration date
   • Scopes: Select the permissions you need:
     • Work Items: Read & Write
     • Code: Read
     • Build: Read
     • Or select Full Access for all permissions

5. Click Create

6. Copy the token - you won't be able to see it again.

7. Set up the PAT as an environment variable:

   For Windows (PowerShell):

   $env:AZURE_DEVOPS_PAT = "your-pat-token-here"

   For Windows (CMD):

   set AZURE_DEVOPS_PAT=your-pat-token-here

   For macOS/Linux:

   export AZURE_DEVOPS_PAT="your-pat-token-here"

   For macOS/Linux (Permanent setup):

   Add to your ~/.zshrc or ~/.bashrc:

   echo 'export AZURE_DEVOPS_PAT="your-pat-token-here"' >> ~/.zshrc source ~/.zshrc
