--- name: azure-devops-rest-api description: Guide for working with Azure DevOps REST APIs and OpenAPI specifications. Use this skill when implementing new Azure DevOps API integrations, exploring API capabilities, understanding request/response formats, or referencing the official OpenAPI specifications from the vsts-rest-api-specs repository. --- # Azure DevOps REST API ## Overview This skill provides guidance for working with Azure DevOps REST APIs using the official OpenAPI specifications from the [vsts-rest-api-specs](https://github.com/MicrosoftDocs/vsts-rest-api-specs) repository. It helps with implementing new API integrations, understanding API capabilities, and referencing the correct request/response formats. ## Key API Areas Azure DevOps REST APIs are organized into the following main areas: ### Core Services - **core** - Projects, teams, processes, and organization-level operations - **git** - Repositories, branches, pull requests, commits - **build** - Build definitions, builds, and build resources - **pipelines** - Pipeline definitions and runs - **release** - Release definitions, deployments, and approvals ### Work Item & Planning - **wit** (Work Item Tracking) - Work items, queries, and work item types - **work** - Boards, backlogs, sprints, and team configurations - **testPlan** - Test plans, suites, and cases - **testResults** - Test runs and results ### Package & Artifact Management - **artifacts** - Artifact feeds and packages - **artifactsPackageTypes** - NuGet, npm, Maven, Python packages ### Security & Governance - **graph** - Users, groups, and memberships - **security** - Access control lists and permissions - **policy** - Branch policies and policy configurations - **audit** - Audit logs and events ### Extension & Integration - **extensionManagement** - Extensions and marketplace - **serviceEndpoint** - Service connections - **hooks** - Service hooks and subscriptions ## API Specification Structure The vsts-rest-api-specs repository is organized by API area and version: ``` specification/ ├── {api-area}/ (e.g., git, build, pipelines) │ ├── 7.2/ Latest stable version │ │ ├── {area}.json OpenAPI spec file │ │ └── httpExamples/ Example requests/responses │ ├── 7.1/ │ └── ... ``` ### Using the Specifications 1. **Identify the API area** - Determine which service area (git, build, wit, etc.) contains the functionality needed 2. **Select the version** - Use the latest version (7.2) unless targeting a specific Azure DevOps Server version 3. **Review the OpenAPI spec** - The main `{area}.json` file contains all endpoints, schemas, and parameters 4. **Check httpExamples** - Real request/response examples for each endpoint ## Implementation Patterns ### Pattern 1: Exploring New API Capabilities When exploring what APIs are available for a specific feature: 1. Clone the vsts-rest-api-specs repository to `/tmp/vsts-rest-api-specs` 2. Browse the specification directory for the relevant API area 3. Review the OpenAPI spec JSON file for available endpoints 4. Check httpExamples for real-world usage patterns Example workflow: ```bash cd /tmp git clone --depth 1 https://github.com/MicrosoftDocs/vsts-rest-api-specs.git cd vsts-rest-api-specs/specification/git/7.2 # Review git.json for endpoint definitions # Check httpExamples/ for request/response samples ``` ### Pattern 2: Implementing a New API Feature When adding new API functionality to the MCP server: 1. **Locate the spec**: Find the relevant OpenAPI specification 2. **Review the schema**: Understand the request parameters and response format 3. **Check examples**: Review httpExamples for real request/response data 4. **Create types**: Define TypeScript interfaces based on the OpenAPI schema 5. **Implement handler**: Create the feature handler following the repository's feature-based architecture 6. **Add tests**: Write unit tests with mocked responses based on httpExamples ### Pattern 3: Understanding Request/Response Formats When you need to understand the exact format of API requests or responses: 1. Navigate to `specification/{area}/{version}/httpExamples/` 2. Find the relevant endpoint example (e.g., `GET_repositories.json`) 3. Review both the request parameters and response body structure 4. Use this as the basis for creating Zod schemas and TypeScript types ## Reference Resources ### scripts/ Contains helper utilities for working with the API specifications: - `clone_specs.sh` - Clone or update the vsts-rest-api-specs repository - `find_endpoint.py` - Search for specific endpoints across all API specs ### references/ Contains curated reference documentation: - `api_areas.md` - Comprehensive list of all API areas and their purposes - `common_patterns.md` - Common request/response patterns across APIs - `authentication.md` - API authentication methods and patterns ### Usage Tips **Finding the right API:** - Use the OpenAPI spec's `paths` section to find endpoint URLs - Check the `tags` property to understand the API category - Review the `operationId` for the internal Azure DevOps method name **Understanding schemas:** - All data models are in the `definitions` section of the OpenAPI spec - Look for `$ref` properties to follow schema references - Use httpExamples to see actual data structures **Version selection:** - Use version 7.2 for Azure DevOps Services (cloud) - Check azure-devops-server-{version} folders for on-premises versions - API versions are additive - newer versions include all older functionality ## Integration with This Repository When implementing features in this MCP server: 1. **Follow the feature-based architecture**: Create features in `src/features/{api-area}/` 2. **Use Zod for validation**: Define schemas based on OpenAPI definitions 3. **Reference the specs**: Link to the relevant OpenAPI spec in code comments 4. **Include examples**: Use httpExamples data for test fixtures 5. **Match naming**: Use consistent naming with the Azure DevOps API (e.g., `repositoryId`, `pullRequestId`) Example feature implementation pattern: ```typescript // src/features/{api-area}/{operation}/ ├── feature.ts // Core implementation using azure-devops-node-api ├── schema.ts // Zod schemas based on OpenAPI definitions ├── feature.spec.unit.ts // Tests using httpExamples data └── index.ts // Exports ```
