Get the full configuration of a specific pipeline by application and pipeline name. Use this to inspect pipeline stages, triggers, and parameters before triggering or modifying it. Returns the complete pipeline JSON definition including all stage configurations.

Get the version history of a pipeline configuration showing past revisions. Use this to audit changes to a pipeline or compare previous configurations. Returns JSON array of historical pipeline versions ordered by update time.

Get scaling activities for a server group in a Spinnaker cluster. Use this to audit recent auto-scaling events (scale-up, scale-down) and diagnose capacity issues. Returns JSON array of scaling activity records with timestamps, descriptions, and status.

Get a specific server group in a Spinnaker cluster using a target selection strategy (e.g., newest, oldest, largest, smallest, fail). Use this when you need the most recently deployed or a specific server group without knowing its exact name. Returns JSON with the matched server group details.

Get the status and details of a Spinnaker orchestration task (e.g., deploy, resize, rollback, delete). Use this to monitor the progress of a long-running infrastructure operation. Returns JSON with task status, start/end times, retry info, and step-by-step execution details.

List all configured Spinnaker accounts (cloud provider integrations). Use this to discover available cloud accounts before querying infrastructure or deploying. Returns JSON array of account objects with provider type, environment, and permissions.

List all Spinnaker applications with their metadata. Use this as a starting point to discover available applications before querying pipelines or infrastructure. Returns JSON array of application objects with name, email, accounts, and cloud providers.

List all cluster names for a Spinnaker application, grouped by account. Use this to discover clusters before drilling into a specific one with get_cluster. Returns JSON object mapping account names to arrays of cluster names.

List recent pipeline executions for a Spinnaker application, optionally filtered by status. Use this to monitor deployment activity or find a specific execution ID. Returns JSON array of execution summaries with status, timing, and trigger info. Use get_execution for full details of a specific run.

List all firewall rules (security groups) across all Spinnaker accounts and regions. Use this to audit network security posture or find a specific security group before inspecting it with get_firewall. Returns JSON array of firewall objects grouped by account and region.

List all load balancers for a Spinnaker application across all accounts and regions. Use this to inspect network routing and health check configuration for an application. Returns JSON array of load balancer objects with listener, health check, and attached server group details.

List all networks (VPCs) across all Spinnaker accounts and cloud providers. Use this to discover available networks when configuring deployment targets or security groups. Returns JSON array of network objects with provider, account, and CIDR details.

List all pipeline configurations for a Spinnaker application. Use this to discover available pipelines before triggering or inspecting a specific one. Returns JSON array of pipeline configuration objects with name, stages, triggers, and parameters.

List all server groups (ASGs, instance groups, replica sets) for a Spinnaker application. Use this to view active deployment targets and their instance counts across regions and accounts. Returns JSON array of server group objects with instance counts, cloud provider details, and region info.

List all deployment strategy configurations for a Spinnaker application. Use this to discover available strategies (e.g., red/black, rolling, canary) before saving or modifying one. Returns JSON array of strategy configuration objects.

List all subnets for a given cloud provider across Spinnaker accounts. Use this to discover available subnets when configuring server groups or deployment targets. Returns JSON array of subnet objects with CIDR, availability zone, and VPC association.

Pause a running pipeline execution at the current stage boundary. Use this to temporarily halt a deployment for manual review before it continues to the next stage. The execution can be resumed later with resume_execution. Returns a confirmation message.

Restart a specific failed or completed stage within a pipeline execution. Use this to retry a stage that failed due to a transient error without re-running the entire pipeline. Requires the execution ID and stage ID. Returns a confirmation message.

Resume a previously paused pipeline execution, continuing from where it was halted. Use this after pause_execution once the manual review or intervention is complete. Returns a confirmation message.

Save a new pipeline configuration to Spinnaker. Use this to create a brand-new pipeline definition — use update_pipeline instead to modify an existing one. Accepts a full pipeline JSON definition and returns a confirmation. This is a mutating operation that creates a new pipeline visible in the Spinnaker UI.

Save a new deployment strategy configuration to Spinnaker. Use this to create a reusable deployment strategy (e.g., red/black, rolling push, canary) — use delete_strategy to remove one. Accepts a full strategy JSON definition and returns a confirmation.

Search pipeline executions across an application with rich filters such as status, trigger type, and time range. Use this instead of list_executions when you need to find executions matching specific criteria. Returns JSON array of matching execution summaries.

Trigger a new pipeline execution with optional parameters. Use this to start a deployment, build, or any configured pipeline workflow. Returns the execution reference ID that can be passed to get_execution or list_executions to monitor progress. This is a mutating operation that starts a real pipeline run.

Update an existing pipeline configuration in Spinnaker. Use this to modify stages, triggers, or parameters of a pipeline that already exists — use save_pipeline instead to create a new one. Accepts a full pipeline JSON definition and returns a confirmation. This is a mutating operation that overwrites the current pipeline config.
