Is Eve safe? Promising trust profile, but some evidence still deserves review.
Compare Eve
How does it stack up against its Needs review neighbours?
Pick any agent to compare →In detail: Eve scores 67.0/100 (Grade B), ranked #458 of 1374 tracked open-source AI agent projects, on evidence coverage C (2 of 5 independent signal types). The public evidence: no package-provenance attestation found; OSSF Scorecard rates its supply-chain practices 5.9/10; 100% of recent commits are signed; last pushed 2026-10-30. Every point is earned from checkable signals — never paid placement. How scoring works →
How Eve 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 Eve and whether that has changed: from the source repository, through how changes are reviewed and released, to the code you run. These are the checks for OWASP ASI04 Agentic Supply Chain Vulnerabilities.

Source Signed
github.com/vercel/eve, Apache-2.0, last pushed 2026-10-30. 100% of the last 100 commits carry a verified signature, so changes trace to a verified account.

Review and release Mixed
OpenSSF Scorecard rates the repository's practices 5.9/10 (scanned Oct 19, 2026). The checks that decide who can get a change released:
- Code Review10
- Branch Protection4
- Signed Releasesn/a
- Dangerous Workflow10
- Token Permissions0
- Pinned Dependencies9

Published packages None
No registry package. Eve is used from its repository, so what you run is whatever you check out: pin a release tag or commit.
Changes to this chain

Verify this score yourself
Every build re-issues Eve’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.
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.

Quick Trust Read
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 C is separate — it grades how many independent signal types back the score (2 of 5), so a high score on thin evidence stays visible. Full methodology →

Does Eve publish package provenance?
Does Eve have an OpenSSF Scorecard?
Is Eve actively maintained?
What license does Eve use?
Are Eve's commits signed?
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.

MCP, providers, tool surface
These runtime-trust fields — detected from public repo docs and manifests — contribute a bounded adjustment to this project's HVTrust score alongside supply-chain evidence.

Detected changes to Eve's runtime surface and supply-chain posture, from daily public-signal snapshots. A change here means our detectors see something different — a genuinely changed capability, or better evidence of an existing one.
Maintain Eve?
For maintainers
HVTrust scores Eve 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.
