#107

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 →

Common questions about MCP Server Polarion

Public supply-chain signals for MCP Server Polarion are strong: it has multiple independent trust indicators in place. This does not replace your own security review, but MCP Server Polarion carries less obvious unverified-evidence risk than projects with thin signals.

Does MCP Server Polarion publish package provenance?

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

Does MCP Server Polarion have an OpenSSF Scorecard?

MCP Server Polarion has an OpenSSF Scorecard score of 6.5/10. 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 MCP Server Polarion actively maintained?

Actively maintained. The repository was pushed to within the last 3 day(s).

What license does MCP Server Polarion use?

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

Are MCP Server Polarion's commits signed?

100% of the last 100 commits to MCP Server Polarion 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.
