Can my AI agent figure out exactly which pod/node failed in an active workflow execution?

Yes. If a workflow fails, you can ask your agent to retrieve the workflow tree by name. The agent uses the `get_workflow` tool to inspect the deeply nested structure, traverse the active nodes, and pinpoint the exact step or container that resulted in an error state without you ever needing to click through the Argo UI.

Can I list only scheduled periodic jobs across my cluster?

Absolutely. You can use the dedicated `list_cron_workflows` capability to isolate and return strictly workloads orchestrated on a time schedule across any namespace, saving you from parsing through thousands of isolated runs.

Do I need to expose my internal Kubernetes API to use this?

No. The integration strictly interfaces with the Argo Server UI/API layer via standard REST traffic using a scoped ServiceAccount Bearer token. Your cluster's overarching master `kube-apiserver` remains safely isolated from external agentic logic.

About Argo Workflows MCP Server

Connect your Argo Workflows cluster to any AI agent and take full control of your infrastructure orchestration through natural conversation.

LlamaIndex agents combine Argo Workflows tool responses with indexed documents for comprehensive, grounded answers. Connect 6 tools through Vinkius and query live data alongside vector stores and SQL databases in a single turn. ideal for hybrid search, data enrichment, and analytical workflows.

What you can do

Active Workflows — List and query all running, pending, or recently completed workflow executions across your Kubernetes namespaces
Deep Inspection — Dive into specific workflow instances to inspect their precise resource trees, node statuses, and pod parameters to catch failures
Templates & Crons — Browse parameterized, reusable WorkflowTemplates and analyze recurring CronWorkflows orchestrating scheduled jobs
Historical Archives — Search archived workflows that hit your database to understand historical infrastructure patterns

The Argo Workflows MCP Server exposes 6 tools through the Vinkius. Connect it to LlamaIndex in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
