Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| list_applicationsA | List ArgoCD applications with optional filtering. Returns applications matching the specified filters. Use this to get an overview of applications in a project or find unhealthy/out-of-sync apps. |
| get_applicationB | Get detailed information about a specific ArgoCD application. Returns comprehensive application details including source repo, sync status, health status, deployment destination, and any conditions or errors. |
| get_application_statusB | Get condensed health and sync status for quick checks. Use this for a quick status check when you don't need full application details. |
| get_application_diffA | Preview what would change on sync (dry-run diff). Shows resources that would be created, updated, or deleted if sync were triggered. Use this before syncing to understand the impact. |
| get_application_historyA | View deployment history with commit info and timestamps. Shows recent deployments including revision, timestamp, and initiator. Useful for understanding recent changes and finding rollback targets. |
| diagnose_sync_failureB | Diagnose why an application sync failed. Aggregates sync status, resource conditions, events, and recent logs to identify root cause. Provides actionable suggestions for resolution. |
| get_application_logsA | Get pod logs for an application. Retrieves logs from pods managed by the application. Useful for debugging application issues, checking startup errors, or monitoring runtime behavior. |
| list_clustersB | List registered Kubernetes clusters with health status. Shows all clusters registered with ArgoCD and their connection status. |
| list_projectsA | List ArgoCD projects. Shows all projects which organize and control application access. |
| sync_applicationA | |
| refresh_applicationB | Force manifest refresh from Git. Triggers ArgoCD to re-fetch manifests from the Git repository. Use hard=true to invalidate cache and force full refresh. |
| rollback_applicationB | |
| terminate_syncB | Terminate an ongoing sync operation. Stops a sync that's currently in progress. Useful when a sync is stuck, taking too long, or was triggered by mistake. |
| delete_applicationA | |
| sync_application_with_pruneA | |
