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 A 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 Cap Js MCP Server safe?

Does Cap Js MCP Server publish package provenance?

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

Does Cap Js MCP Server have an OpenSSF Scorecard?

Cap Js MCP Server has an OpenSSF Scorecard score of 6.1/10. 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 Cap Js MCP Server actively maintained?

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

What license does Cap Js MCP Server use?

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

Are Cap Js MCP Server's commits signed?

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.
