Drone CI API
Drone CI REST API allows agents to manage repository pipelines, trigger builds, inspect build and step logs, and administer secrets for container-native CI/CD pipelines running on self-hosted or Drone Cloud infrastructure.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
TLS depends on operator configuration for self-hosted instances. No token scopes. Repository secrets are encrypted at rest but decryption keys depend on operator-managed configuration.
⚡ Reliability
Best When
Best when your team runs container-native pipelines on self-hosted Drone and needs agents to automate build orchestration and secret management without a third-party SaaS dependency.
Avoid When
Avoid when infrastructure operations burden is unacceptable or when you need a vendor-backed SLA and enterprise support contract.
Use Cases
- • Trigger a pipeline build programmatically after a deployment artifact is published to a registry
- • Poll step-level logs for a running build and surface failure output in a Slack alert
- • Create or rotate repository-scoped secrets without requiring manual dashboard access
- • List and cancel queued builds during a freeze window or incident response
- • Sync repository activation state across a fleet of microservices during org-wide onboarding
Not For
- • Teams that need a fully managed SaaS CI with enterprise SLA guarantees (self-hosted ops overhead is real)
- • Complex DAG-based workflows requiring conditional fan-out across dozens of heterogeneous runners
- • Organizations that need deep LDAP/SSO integration without custom Drone plugin development
Interface
Authentication
Authentication uses a User Token generated from the Drone dashboard or CLI, passed as a Bearer token. Tokens are per-user and grant access matching that user's repository permissions. No fine-grained scopes exist; machine accounts are the recommended pattern for agent use.
Pricing
The core Drone server is Apache 2.0 licensed. Harness acquired Drone and the enterprise featureset is now marketed under Harness CI. Self-hosted OSS version remains free.
Agent Metadata
Known Gotchas
- ⚠ Repository must be explicitly activated via the API or dashboard before builds can be triggered — silent failures occur if the repo is not activated
- ⚠ Build numbers are auto-incremented and there is no deduplication — agents that retry on timeout will create duplicate builds
- ⚠ Log retrieval for individual steps uses a different endpoint pattern than build-level logs and may return empty if the step has not yet started
- ⚠ Self-hosted instances may have non-standard base URLs; agents must be configured per-instance rather than using a global endpoint
- ⚠ The token has no scope restrictions — compromising it grants full access to all repositories the user can see
