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 C 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 Yahoo Finance

Yahoo Finance 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 Yahoo Finance publish package provenance?

No published build provenance is currently detected for Yahoo Finance. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.

Does Yahoo Finance have an OpenSSF Scorecard?

Yahoo Finance has an OpenSSF Scorecard score of 4.3/10. 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 Yahoo Finance actively maintained?

Actively maintained. The repository was pushed to within the last 6 day(s).

What license does Yahoo Finance use?

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

Are Yahoo Finance's commits signed?

83% of the last 100 commits to Yahoo Finance 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.
