How Google Surf MCP 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 Google Surf MCP 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.

Source Partly signed

github.com/HarimxChoi/google-surf-mcp, MIT, last pushed 2026-09-10. 32% of the last 100 commits carry a verified signature; the rest can't be tied to a verified identity.

Verify this score yourself

Every build re-issues Google Surf MCP’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.

Raise Scorecard signals Current OSSF Scorecard is 3.2/10. Tighten the weakest checks to improve public safety evidence.

Publish provenance Add package provenance or release attestations so users can verify where shipped artifacts came from.

Increase signed commits Raise the share of verified-signed commits to make maintainer identity and release history easier to trust.

Refresh maintenance signals The repo was last pushed 36 days ago. Fresh activity helps separate stable projects from stale ones.

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 Google Surf MCP

Public trust evidence for Google Surf MCP 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 Google Surf MCP publish package provenance?

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

Does Google Surf MCP have an OpenSSF Scorecard?

Google Surf MCP has an OpenSSF Scorecard score of 3.2/10. 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 Google Surf MCP actively maintained?

Slowing down. Last push was 36 days ago — keep an eye on whether activity resumes.

What license does Google Surf MCP use?

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

Are Google Surf MCP's commits signed?

32% of the last 100 commits to Google Surf 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.

Maintain Google Surf MCP?

For maintainers

HVTrust scores Google Surf MCP 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.
