How Apple Mail 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 Apple Mail 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/imdinu/apple-mail-mcp, GPL-3.0, last pushed 2026-11-04. 22% 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 Apple Mail 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 B 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 Apple Mail MCP

Apple Mail 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 Apple Mail MCP publish package provenance?

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

Does Apple Mail MCP have an OpenSSF Scorecard?

Apple Mail MCP has an OpenSSF Scorecard score of 4.0/10. 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 Apple Mail MCP actively maintained?

Actively maintained. The repository was pushed to within the last 6 day(s).

What license does Apple Mail MCP use?

Apple Mail MCP ships under GPL-3.0. A declared, OSI-approved license is one of the transparency signals HVTrust scores.

Are Apple Mail MCP's commits signed?

22% of the last 100 commits to Apple Mail 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.
