## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-23.

- **Supply Chain Security**: 0/100
  - Malware scan not yet available for this package.
  - Known CVEs could not be checked: this artifact ships no SBOM, so there is no dependency list to read. Publishing one would let us assess it.
  - Install-script risk not yet assessed.
  - Dependency health could not be checked: this artifact ships no SBOM, so there is no dependency list to read. Publishing one would let us assess it.
- **Provenance & Transparency**: 48/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (Apache-2.0).
  - Actively maintained (last published 5 days ago).
  - Publishes a security disclosure policy (SECURITY.md).
- **Schema Quality & AI Usability**: 0/100
  - Schema quality not yet verified: this package installed, but its server did not start, so we have no schema to assess.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: this package installed, but its server did not start, so we have no schema to compare.
- **Tool Coverage**: 0/100
  - Tool coverage not yet verified: this package installed, but its server did not start, so we have no tool definitions to assess.
- **Capabilities**: 0/100
  - Protocol version not yet verified: this package installed, but its server did not start, so we never saw its MCP handshake.

**Unverified: 5 categories.** Categories scored 0 because we could not verify them: 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.

## Common questions

### What is the Janus MCP server?

Janus is an MCP server listed in the public MCP registry as io.github.tonylchang/janus-mcp. Secure Kubernetes MCP server: scoped, redacted diagnostics and human-approved writes. This page covers its container image (ghcr.io/tonylchang/janus-mcp:v0.4.1).

### Is the Janus MCP server safe to use?

Janus scores 10 out of 100 on VerifyMCP. 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.

### Is the Janus MCP server still maintained?

Janus is still listed as active in the MCP registry. We last reached this channel on 23 August 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 Janus MCP server under?

Janus 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.
