GitHub Actions REST API
GitHub's REST API for managing Actions workflows — trigger runs, check status, download artifacts, manage secrets, and control runner infrastructure programmatically from agents.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Fine-grained PATs for minimal repository and Actions-scoped permissions. GitHub App installation tokens for org-level management. Actions secrets write-only via API — safe by design. SOC 2 Type II, ISO 27001.
⚡ Reliability
Best When
Your agent needs to trigger, monitor, or manage GitHub Actions workflows as part of a deployment or automation pipeline.
Avoid When
You need real-time workflow log streaming or are not on GitHub — use the GitHub MCP server for broader GitHub workflow management.
Use Cases
- • Triggering CI/CD workflow runs programmatically from deployment agents
- • Monitoring workflow run status and downloading build artifacts from pipelines
- • Managing repository secrets and environment variables for secure agent deployments
- • Re-running failed jobs automatically from incident response agents
- • Creating custom GitHub Actions deployment gates from agent-based approval workflows
Not For
- • GitLab or Bitbucket CI/CD (GitHub-specific)
- • Running Actions on GitHub infrastructure without a GitHub repository
- • Real-time log streaming during workflow runs (logs available only after completion via API)
Interface
Authentication
GitHub Personal Access Token (PAT) or GitHub App installation token. Fine-grained PATs can scope to specific repos and actions:write, actions:read permissions. Classic PATs use repo scope.
Pricing
API access is free. Actions compute time is what costs money. API calls count against your 5,000 req/hour GitHub API quota.
Agent Metadata
Known Gotchas
- ⚠ workflow_dispatch event trigger returns 204 with no run ID — agents must list recent runs after trigger to find the new run ID
- ⚠ Artifact download URLs expire in 1 minute — agents must download artifacts immediately after getting URL
- ⚠ Actions secrets cannot be read via API (only created/updated/deleted) — agents cannot retrieve secret values
- ⚠ Workflow file must have workflow_dispatch trigger enabled to be triggerable via API — check workflow YAML first
- ⚠ GitHub search API (for searching workflow runs by criteria) has a 30 req/minute rate limit separate from main API
