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 D 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 Codex MCP Tool

Public trust evidence for Codex MCP Tool is thin: several supply-chain signals are missing or weak. This does not mean the project is unsafe — it means an outside observer cannot easily verify the usual integrity checks. Treat with extra scrutiny.

Does Codex MCP Tool publish package provenance?

No published build provenance is currently detected for Codex MCP Tool. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.

Does Codex MCP Tool have an OpenSSF Scorecard?

Codex MCP Tool has an OpenSSF Scorecard score of 2.6/10. 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 Codex MCP Tool actively maintained?

Maintained. Last push was 20 days ago.

What license does Codex MCP Tool use?

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

Are Codex MCP Tool's commits signed?

3% of the last 100 commits to Codex MCP Tool 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.
