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 C is separate — it grades how many independent signal types back the score (2 of 5), so a high score on thin evidence stays visible. Full methodology →

Is Storybook MCP Addon safe?

Public trust evidence for Storybook MCP Addon 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 Storybook MCP Addon publish package provenance?

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

Does Storybook MCP Addon have an OpenSSF Scorecard?

No OpenSSF Scorecard data is currently published for Storybook MCP Addon. 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 Storybook MCP Addon actively maintained?

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

What license does Storybook MCP Addon use?

Storybook MCP Addon ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.

Are Storybook MCP Addon's commits signed?

31% of the last 100 commits to Storybook MCP Addon 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.
