Codex MCP Go

Repository

codex-mcp-go is a Go-based MCP (Model Context Protocol) server that serves as a bridge for Codex CLI, enabling various AI coding assistants (such as Claude Code, Roo Code, KiloCode, etc.) to seamlessly collaborate with Codex.

In detail: Codex MCP Go scores 51.7/100 (Grade C), ranked #955 of 1378 tracked open-source AI agent projects, on evidence coverage B (3 of 5 independent signal types). The public evidence: its packages ship with cryptographic provenance; OSSF Scorecard rates its supply-chain practices 3.0/10; 1% of recent commits are signed; no published advisory affects its latest release (@zenfun510/codex-mcp-go); last pushed 2026-02-03. Every point is earned from checkable signals — never paid placement. How scoring works →

How Codex MCP Go could raise its score

Each line changes one public signal and recomputes with the live scoring function. The gains don't add up exactly, because the score is capped near the top.

Chain of custody

Scanners check what the code says. This traces who ships Codex MCP Go and whether that has changed: from the source repository, through how changes are reviewed and released, to the package you install. These are the checks for OWASP ASI04 Agentic Supply Chain Vulnerabilities.

  1. Source Partly signed

    github.com/w31r4/codex-mcp-go, MIT, last pushed 2026-02-03. 1% of the last 100 commits carry a verified signature; the rest can't be tied to a verified identity.

  2. Review and release Weak

    OpenSSF Scorecard rates the repository's practices 3.0/10 (scanned Oct 8, 2026). The checks that decide who can get a change released:

Verify this score yourself

Every build re-issues Codex MCP Go’s score as an Ed25519-signed credential, valid for 7 days. You can check it offline against HVTracker’s published key; if anyone changes a number after signing, verification fails.

Signed credential (JSON) How to verify

What this score doesn’t check

It covers who ships the code, not what the code does. It doesn’t read tool descriptions or prompts for injected instructions, watch runtime behaviour, or find bugs nobody has disclosed yet. For that, run a content scanner before you connect it, such as Cisco MCP Scanner or Snyk Agent Scan.

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 Codex MCP Go

Public trust evidence for Codex MCP Go 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 Go publish package provenance?
Yes. Codex MCP Go's package releases carry build provenance attestations, which cryptographically link the published package back to its source repository and CI workflow.
Does Codex MCP Go have an OpenSSF Scorecard?
Codex MCP Go has an OpenSSF Scorecard score of 3.0/10. 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 Go actively maintained?
Stale. The repository has not been pushed to in 255 days. Consider whether the project is still being maintained.
What license does Codex MCP Go use?
Codex MCP Go ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are Codex MCP Go's commits signed?
1% of the last 100 commits to Codex MCP Go 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.

Maintain Codex MCP Go?

For maintainers

HVTrust scores Codex MCP Go from public signals only — we never contact maintainers first. If a signal is wrong, stale, or missing (provenance you publish, a Scorecard you run, signed releases), tell us and we'll review it. Corrections are public and tracked on GitHub.
