Is ARC-1 safe? ARC-1 scores 73.1/100 (Grade B), ranked #108 of 1283 tracked open-source AI agent projects, on evidence coverage B (3 of 5 independent signal types). The public evidence: its packages ship with cryptographic provenance; no OSSF Scorecard result yet; 100% of recent commits are signed; last pushed 2026-08-11. Every point is earned from checkable signals — never paid placement. How scoring works →

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 B 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 →

Is ARC-1 safe?

ARC-1 has a mixed signal profile. Some trust indicators are present, others are missing. Whether it is safe for your use case depends on which gaps matter to you — review the breakdown below before adopting in production.
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?
No OpenSSF Scorecard data is currently published for ARC-1. 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 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.
