In detail: Growthbook MCP scores 75.8/100 (Grade B), ranked #240 of 1378 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; OSSF Scorecard rates its supply-chain practices 5.3/10; 33% of recent commits are signed; no published advisory affects its latest release (@growthbook/mcp); last pushed 2026-10-08. Every point is earned from checkable signals — never paid placement. How scoring works →

How Growthbook MCP could raise its score

Each line changes one public signal and recomputes with the live scoring function. The gains don't add up exactly, because the score is capped near the top.

Chain of custody

Scanners check what the code says. This traces who ships Growthbook MCP and whether that has changed: from the source repository, through how changes are reviewed and released, to the package you install. These are the checks for OWASP ASI04 Agentic Supply Chain Vulnerabilities.

  1. Source Partly signed

    github.com/growthbook/growthbook-mcp, MIT, last pushed 2026-10-08. 33% of the last 100 commits carry a verified signature; the rest can't be tied to a verified identity.

  2. Review and release Mixed

    OpenSSF Scorecard rates the repository's practices 5.3/10 (scanned Oct 16, 2026). The checks that decide who can get a change released:

Verify this score yourself

Every build re-issues Growthbook MCP’s score as an Ed25519-signed credential, valid for 7 days. You can check it offline against HVTracker’s published key; if anyone changes a number after signing, verification fails.

What this score doesn’t check

It covers who ships the code, not what the code does. It doesn’t read tool descriptions or prompts for injected instructions, watch runtime behaviour, or find bugs nobody has disclosed yet. For that, run a content scanner before you connect it, such as Cisco MCP Scanner or Snyk Agent Scan.

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 →

Common questions about Growthbook MCP

Public supply-chain signals for Growthbook MCP are strong: it has multiple independent trust indicators in place. This does not replace your own security review, but Growthbook MCP carries less obvious unverified-evidence risk than projects with thin signals.
Does Growthbook MCP publish package provenance?
Yes. Growthbook MCP's package releases carry build provenance attestations, which cryptographically link the published package back to its source repository and CI workflow.
Does Growthbook MCP have an OpenSSF Scorecard?
Growthbook MCP has an OpenSSF Scorecard score of 5.3/10. 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 Growthbook MCP actively maintained?
Maintained. Last push was 8 days ago.
What license does Growthbook MCP use?
Growthbook MCP ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are Growthbook MCP's commits signed?
33% of the last 100 commits to Growthbook MCP 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 Growthbook MCP?

For maintainers

HVTrust scores Growthbook MCP 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.
