Maintainer Checklist
Raise Scorecard signalsCurrent OSSF Scorecard is 5.1/10. Tighten the weakest checks to improve public safety evidence.
Publish provenanceAdd package provenance or release attestations so users can verify where shipped artifacts came from.
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 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 Mastra safe?
Public trust evidence for Mastra 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 Mastra publish package provenance?
No published build provenance is currently detected for Mastra. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.
Does Mastra have an OpenSSF Scorecard?
Mastra has an OpenSSF Scorecard score of 5.1/10. 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 Mastra actively maintained?
Actively maintained. The repository was pushed to within the last 1 day(s).
What license does Mastra use?
Mastra ships under NOASSERTION. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are Mastra's commits signed?
94% of the last 100 commits to Mastra 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.

How this surface has changed
Detected changes to Mastra's runtime surface and supply-chain posture, from daily public-signal snapshots. A change here means our detectors see something different — a genuinely changed capability, or better evidence of an existing one.
Runtime surface grew — new detected provider dependencies: Anthropic, Google Gemini, OpenAI, Postgres, Tavily

Maintain Mastra?
HVTrust scores Mastra 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.
