Argo CD MCP
Argoproj-Labs-blessed Argo CD MCP server, originally donated by Akuity. Both stdio and HTTP-stream transports out of the box, MCP_READ_ONLY mode for production safety, and a tool surface covering the full Argo CD application lifecycle (list/get/sync/delete plus resource-tree traversal and workload logs).
“The Argoproj-Labs-blessed Argo CD MCP server, originally donated by Akuity engineers (the company behind the commercial Argo CD distribution). Pick this when you want an AI agent to triage Argo CD application sync state, drift, and resource trees, backed by the experimental layer of a CNCF-graduated project governance umbrella. Read-only mode (MCP_READ_ONLY=true) cleanly disables write tools for production-safe deployments. The full app lifecycle is covered: list, get, create, update, delete, sync applications, plus resource-tree traversal, managed-resource diff, workload logs, resource events, and custom actions. Self-signed cert support documented for on-prem Argo CD installs. Argoproj-Labs is the Argo Project experimental incubator, distinct from the core argo-cd repository.”

8 TOOLS AVAILABLE
OUR ASSESSMENT
- Argoproj-Labs governance via the Argo Project experimental layer.
- Originally donated by Akuity engineers (the company behind the commercial Argo CD distribution).
- Both stdio and HTTP-stream transports supported out of the box.
- Stateless HTTP mode for HPA-scaled deployments; avoids session-affinity bugs.
- Read-only mode via MCP_READ_ONLY=true cleanly disables write tools.
- Apache-2.0 licence; friction-free for redistribution and enterprise use.
- 13 releases shipped; npm + Docker distribution.
- Self-signed cert support documented for on-prem Argo CD installs.
- 1 commit on default branch in the last 30 days; release cadence is monthly with weekly bursts around release windows.
- `list_applications` known to return excessive tokens at scale (#59 still open); mitigate with filters or read-only-mode tool subset.
- CLI-mode hang reported (#44) when run interactively; safer in stdio-from-IDE configs.
- TLS option NODE_TLS_REJECT_UNAUTHORIZED=0 for self-signed CAs is documented as a footgun and warrants Studio-side guidance.
- Argoproj-Labs is the experimental layer of the Argo Project, distinct from the core argo-cd repo. Treat governance signal as one tier softer than a core-org publication.
Authenticates via Argo CD API token (ARGOCD_API_TOKEN) plus base URL. Mint a scoped, read-only API token in Argo CD for agent use. Combine with MCP_READ_ONLY=true for double-defence against accidental writes. Use --stateless HTTP mode for HPA-scaled deployments to avoid session-affinity bugs. Avoid NODE_TLS_REJECT_UNAUTHORIZED=0 outside a trusted on-prem network.
GitOps and platform teams running Argo CD as their continuous-delivery control plane, workflows where AI assistants need to safely list, diagnose, and (optionally) sync applications from inside the IDE, and on-prem Argo CD deployments using self-signed certificates.
TECHNICAL DETAILS
ADOPTION METRICS
// Reading this416 stars and 71 forks. argoproj-labs governance plus Akuity donation provenance carry the editorial weight beyond raw star count.
// Reading thisSeventh-ranked in infrastructure. Fills the GitOps gap; complements the cluster-operations Kubernetes servers already in the directory.
SOURCES & VERIFICATION
We don't take any single directory's word for it. Before scoring, we cross-reference 5 public MCP sources, install the server ourselves against the clients we cover, and record when we last re-verified.
The same server, 5 different lenses. We reconcile these signals into our editorial score, which is why our number sometimes diverges from a directory-aggregate star count.
