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 C 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 Companies House MCP

Companies House MCP has a mixed signal profile. Some trust indicators are present, others are missing. Whether it is safe for your use case depends on which gaps matter to you — review the breakdown below before adopting in production.

Does Companies House MCP publish package provenance?

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

Does Companies House MCP have an OpenSSF Scorecard?

Companies House 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 Companies House MCP actively maintained?

Slowing down. Last push was 53 days ago — keep an eye on whether activity resumes.

What license does Companies House MCP use?

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