Azure DevOps PRs (MCP)

This VS Code extension exposes Azure DevOps Git pull requests to agents through a local MCP server. It uses the official MCP TypeScript SDK, azure-devops-node-api, and VS Code's Microsoft authentication provider. No personal access token, client ID, or client secret is created, copied, or maintained.

Use

1. Run Azure DevOps PRs (MCP): Sign In to Azure DevOps. VS Code opens its normal Microsoft sign-in flow when needed.
2. Start an agent conversation. VS Code discovers the Azure DevOps pull requests MCP server automatically.

The server provides list_pull_requests, get_pull_request, open_pull_request_file_diff, create_pull_request, and submit_pull_request. create_pull_request prepares a local draft; submit_pull_request creates the remote pull request and requires confirm: true. Both use source and target refs in refs/heads/... form and the caller's Azure DevOps permissions.

Pass includeChanges: true to get_pull_request to return its latest changed files, including commit IDs and change types. In MCP Apps-capable chat hosts, create_pull_request opens an editable draft card with a compact, capped list of changed files. It offers a Markdown preview switch and submits the final description text through submit_pull_request; the resulting pull request then becomes the interactive review card with current reviewer votes, an Approve PR button, clickable comment counts, and an Open diff button for every changed file. A spinner is shown while the card loads or performs an action.

VS Code manages the signed-in Microsoft session. Manage or sign out of that account through VS Code's Accounts menu. Start a new agent conversation when a token expires to obtain a fresh Azure DevOps token.

Development

Run npm run compile to type-check, lint, and bundle both the extension and the MCP server. Run npm test to execute the extension-host tests. On macOS, the test command uses System keychain certificates when a managed network requires an additional trusted CA. Press F5 in VS Code to launch an Extension Development Host.
