SonarCloud API
SonarCloud — cloud-based static code analysis and code quality platform that detects bugs, vulnerabilities, and code smells across 30+ languages, with a REST API for querying analysis results.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
SOC2 Type II, ISO 27001. GDPR compliant. EU data processing. Token-based auth with no scope granularity is a limitation. SonarSource has strong security focus given product domain.
⚡ Reliability
Best When
Your CI/CD pipeline includes open-source projects or you need multi-language static analysis with quality gate enforcement and a developer-friendly API.
Avoid When
You only need dependency/container scanning — Snyk or Dependabot are more focused for that use case.
Use Cases
- • Agents querying code quality gates to block deployments when quality thresholds are not met
- • Security scanning integration — agents fetching vulnerability reports from SonarCloud for automated security triage
- • CI/CD quality enforcement — agents checking SonarCloud analysis status after PR builds to enforce merge requirements
- • Technical debt tracking — agents monitoring code smell trends and complexity metrics over time for reporting
- • Multi-project quality dashboards — agents aggregating SonarCloud metrics across repositories for portfolio quality views
Not For
- • Runtime application security testing (DAST) — SonarCloud is static analysis, not runtime scanning
- • Container and dependency scanning — use Snyk or Trivy for container/dependency vulnerability management
- • Teams without CI/CD pipelines — SonarCloud requires analysis runs integrated with build systems
Interface
Authentication
User token from SonarCloud account settings. Bearer token in Authorization header or as username in basic auth. Token is account-wide — no scope granularity.
Pricing
Completely free for open-source public repositories — major differentiator. Private repo pricing based on total lines of code analyzed.
Agent Metadata
Known Gotchas
- ⚠ Analysis must be triggered via sonar-scanner CLI in CI/CD — agents cannot trigger analysis via REST API directly
- ⚠ Quality gate status is computed after analysis completes — agents must poll /api/qualitygates/project_status after CI run
- ⚠ Branch analysis for PRs requires different project key format — main branch and PR analysis have separate endpoints
- ⚠ Rate limit (10 req/s) is per-user-token — agents with multiple parallel queries may hit this limit
- ⚠ sonarcloud.io and sonarqube.com have different APIs — self-hosted SonarQube API differs from SonarCloud
