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 →

Is Companies House MCP safe?

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?

No OpenSSF Scorecard data is currently published for Companies House MCP. Maintainers can enable the Scorecard GitHub Action to get a public score; without it, automated supply-chain hygiene is harder for outsiders to verify.

Is Companies House MCP actively maintained?

Maintained. Last push was 8 days ago.

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.

Are Companies House MCP's commits signed?

15% of the last 100 commits to Companies House 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.
