kubernetes-mcp-server

Model Context Protocol (MCP) server for Kubernetes and OpenShift

Runs with mockssource: GitHubGoApache-2.0commit f4a39b17ca4c

Go, Apache-2.0 licensed. The project labels itself: containers, context, kubernetes, kubernetes mcp, mcp, model, modelcontextprotocol and openshift.

kubernetes-mcp-server runs, with stand-ins for the services it depends on. An Argusic agent installed it in 28 minutes and hit 3 errors and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.

Go 1.26.4 installed, kubernetes-mcp-server binary built (102MB), all 39 test packages pass, binary runs and prints help/version, runtime requires a Kubernetes kubeconfig

What the agent ended up with on a clean machine, in its own words. How this is measured

Measured by Argusic on a fresh machine every time. Every number links to its evidence. Argusic Score 92 of 100 (the mean of this project's run scores).

What was measured

From the run that decided this verdict. Every line is a recorded value, not an estimate.

Time lost to each failure while testing kubernetes-mcp-server, drawn from the recorded run
Every bar is a failure the agent recorded, with the time it cost. Drawn from this run, not from anywhere else.

What went wrong, in the agent's own words

The agent's own words, worst first, never rewritten into advice.

  • 3 test suites failing: pkg/http, pkg/kubernetes-mcp-server/cmd (TestHTTPSIGHUP) - all failed with 'dial tcp [::]:port: connect: cannot assign requested address' because IPv6 is disabled in container but test helpers defaulted to IPv65 minutes
  • No Go compiler found in container2 minutes
  • make build failed at lint step: 'parallel golangci-lint is running' due to stale process from earlier run2 minutes

How the result was proved
go test -count=1 -v ./... exit 0, 39 test packages passed, 0 failures. Binary at kubernetes-mcp-server (102MB) responds to --help and --version, fails at runtime expectedly with 'no current-context is set' since no kubeconfig is configured in this container

What was not measured

The other half, so you can see exactly how far this evidence goes. A gap is printed as a gap and never filled in.

Peak GPU memory
this ran on a CPU machine, so there was no GPU to sample
Behaviour over a long run
each attempt uses the smallest documented settings and a fixed time budget, so this measures whether it runs, not how it holds up under load
Behaviour against real services
this run was verified against stand-in services only

The end of the recording

The last lines of the terminal session that decided this verdict, exactly as they were recorded.

All tests pass on the final run too. Here's the summary:

Replay the whole session, every command from a clean machine to this point.

How it was tested

One agent, one container, no human help. It installs the project the way its own documentation says to, runs it, and fixes what breaks. Everything below is recorded as it happened: the terminal session, the log and the exact commit. The full method.

Strengths and limits

Measured facts, not opinions. How this is written.

What went well

  • Installed in 28 minutes.
  • Recovered from all 3 errors without a human stepping in, which says the failures are documented well enough to solve.
  • Licensed Apache-2.0, as reported by its host.

What did not, or is not known

  • Only reached a running state against stand-in services, so nothing here proves it works against the real ones.
  • Measured once so far. A single attempt shows it can run, not that it runs reliably.

Also tested, in the same area

Every one of these was installed and run by Argusic on a clean machine. Nothing appears here that was not tested.

Questions

Does kubernetes-mcp-server run?
kubernetes-mcp-server runs, with mocks standing in for external services. Argusic installed and launched it on a clean machine in 28 minutes, hitting 3 errors on the way, and recorded the session.
How did Argusic test kubernetes-mcp-server?
On a fresh, disposable machine, with every command recorded and the repository pinned at commit f4a39b17ca4c. One attempt is recorded, and the full method is on the methodology page.
What did it cost to test kubernetes-mcp-server?
The run that produced this verdict cost $0.18: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
How long does kubernetes-mcp-server take to install?
28 minutes in the run that decided this verdict, from a clean machine to a running state. That is one measured attempt, not an average.
Does kubernetes-mcp-server need a GPU?
Not to start. Argusic reached a running state on a machine with no GPU.
What goes wrong when installing kubernetes-mcp-server?
3 things broke in the recorded run, and 3 were fixed without human help. Each one, and the time it cost, is listed on this page.
Where is the evidence for kubernetes-mcp-server?
The recorded run is on this page, each linking to its full log and terminal recording, stored with a sha256 fingerprint so it cannot be quietly altered.
