How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security0
- No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.Unverified
- Known CVEs could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.Unverified
- Install-script risk not yet assessed.Unverified
- Dependency health could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.Unverified
Provenance & Transparency100
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to kubestellar/kubestellar-mcp). View diagnostics → Pass
- Clear OSI-approved license (Apache-2.0).Pass
- Actively maintained (last published 0 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability68
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 2376 tokens (~62/item across 38 items; 38 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management87
- Stability observed for 26 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "uninstall_ownership_policy" implies "uninstall" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 38 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities20
- Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28. See how to fix → Fail
Unverified: 1 category
A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

Background: How many MCP packages publish verified provenance →
The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

How do I install the KubeStellar MCP server?
KubeStellar MCP runs locally as a container image, launched with docker run --rm -i -e KUBECONFIG ghcr.io/kubestellar/kubestellar-mcp:0.9.20-nightly.20261024. Ready-made configuration for Claude, Cursor, VS Code, Codex and 3 more is on this page, copied from each client's own documentation.
oci · ghcr.io/kubestellar/kubestellar-mcp
claude mcp add kubestellar-kubestellar-mcp -- docker run --rm -i -e KUBECONFIG ghcr.io/kubestellar/kubestellar-mcp:0.9.20-nightly.20261024
This image reads KUBECONFIG. Set it in your client's env block for this server; docker run -e passes it through to the container.
What is the KubeStellar MCP server?
KubeStellar MCP is listed in the public MCP registry as io.github.kubestellar/kubestellar-mcp. AI-powered Kubernetes diagnostics, RBAC analysis, security checks, and app deployment via MCP. This page covers its container image (ghcr.io/kubestellar/kubestellar-mcp).
Is the KubeStellar MCP server safe to use?
KubeStellar MCP scores 58 out of 100 on VerifyMCP. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the KubeStellar MCP server expose?
KubeStellar MCP exposes 38 tools: list_clusters, get_cluster_health, detect_drift, check_gatekeeper, get_ownership_policy_status, and 33 more. Their descriptions and schemas cost roughly 2,376 tokens of context every time the server is loaded.
Is the KubeStellar MCP server still maintained?
KubeStellar MCP is still listed as active in the MCP registry. We last reached this channel on 24 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the KubeStellar MCP server under?
KubeStellar MCP declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
