Activity sub-score · out of 100

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 A reflects the trust score band: A ≥ 80, B ≥ 65, C ≥ 50, D < 50. Evidence coverage B is separate — it grades how many independent signal types back the score (3 of 5), so a high score on thin evidence stays visible. Full methodology →

Common questions about ARC-1

Public supply-chain signals for ARC-1 are strong: it has multiple independent trust indicators in place. This does not replace your own security review, but ARC-1 carries less obvious unverified-evidence risk than projects with thin signals.

Does ARC-1 publish package provenance?

Yes. ARC-1's package releases carry build provenance attestations, which cryptographically link the published package back to its source repository and CI workflow.

Does ARC-1 have an OpenSSF Scorecard?

ARC-1 has an OpenSSF Scorecard score of 7.0/10. The Scorecard checks for branch protection, signed releases, dependency updates, fuzzing, code review, and other supply-chain hygiene items. See the full check breakdown on this page.

Is ARC-1 actively maintained?

Actively maintained. The repository was pushed to within the last 1 day(s).

What license does ARC-1 use?

ARC-1 ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.

Are ARC-1's commits signed?

100% of the last 100 commits to ARC-1 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 ARC-1?

For maintainers

HVTrust scores ARC-1 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.
