Every point is earned from checkable signals — never paid placement. How scoring works →

How Real Browser 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 Real Browser 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.

github.com/ofershap/real-browser-mcp, MIT, last pushed 2026-11-09. 86% of the last 100 commits carry a verified signature, so changes trace to a verified account.

Verify this score yourself

Every build re-issues Real Browser 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.

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 A 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 Real Browser MCP

Public supply-chain signals for Real Browser MCP are strong: it has multiple independent trust indicators in place. This does not replace your own security review, but Real Browser MCP carries less obvious unverified-evidence risk than projects with thin signals.

Does Real Browser MCP publish package provenance?

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

Does Real Browser MCP have an OpenSSF Scorecard?

Real Browser MCP has an OpenSSF Scorecard score of 5.8/10. 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 Real Browser MCP actively maintained?

Actively maintained. The repository was pushed to within the last 1 day(s).

What license does Real Browser MCP use?

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

Are Real Browser MCP's commits signed?

86% of the last 100 commits to Real Browser 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.
