In MCP Servers

How to read this: HVTrust (0–100) weighs supply-chain signals (provenance, OSSF Scorecard, signed commits, open license) alongside real-world adoption. Grade D reflects the trust score band: A ≥ 80, B ≥ 65, C ≥ 50, D < 50. Evidence coverage D is separate — it grades how many independent signal types back the score (1 of 5), so a high score on thin evidence stays visible. Full methodology →

Is Plumb MCP safe?

Public trust evidence for Plumb MCP is thin: several supply-chain signals are missing or weak. This does not mean the project is unsafe — it means an outside observer cannot easily verify the usual integrity checks. Treat with extra scrutiny.
Does Plumb MCP publish package provenance?
No published build provenance is currently detected for Plumb MCP. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.
Does Plumb MCP have an OpenSSF Scorecard?
No OpenSSF Scorecard data is currently published for Plumb MCP. Maintainers can enable the Scorecard GitHub Action to get a public score; without it, automated supply-chain hygiene is harder for outsiders to verify.
Is Plumb MCP actively maintained?
Maintained. Last push was 18 days ago.
What license does Plumb MCP use?
Plumb MCP ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are Plumb MCP's commits signed?
4% of the last 100 commits to Plumb MCP are verified-signed (GPG, SSH, S/MIME, or GitHub's signing flow). Signed commits help confirm that code was authored by who the commit claims.

Not a safety endorsement. HVTracker describes what public signals show, not whether a project is safe for your use case. Run your own security review before adopting in production.

Maintain Plumb MCP?

For maintainers

HVTrust scores Plumb MCP from public signals only — we never contact maintainers first. If a signal is wrong, stale, or missing (provenance you publish, a Scorecard you run, signed releases), tell us and we'll review it. Corrections are public and tracked on GitHub.
