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 →

Is build123d MCP safe?

Public supply-chain signals for build123d MCP are strong: it has multiple independent trust indicators in place. This does not replace your own security review, but build123d MCP carries less obvious unverified-evidence risk than projects with thin signals.

Does build123d MCP publish package provenance?

Yes. build123d MCP's package releases carry build provenance attestations, which cryptographically link the published package back to its source repository and CI workflow.

Does build123d MCP have an OpenSSF Scorecard?

build123d MCP has an OpenSSF Scorecard score of 4.1/10. 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 build123d MCP actively maintained?

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

What license does build123d MCP use?

build123d MCP ships under Apache-2.0. A declared, OSI-approved license is one of the transparency signals HVTrust scores.

Are build123d MCP's commits signed?
