Is TruLens safe? Thin or incomplete trust evidence. Review carefully before production use.
Compare TruLens
How does it stack up against its Observability & Evaluation neighbours?
Pick any agent to compare →In detail: TruLens scores 47.3/100 (Grade D), ranked #1042 of 1371 tracked open-source AI agent projects, on evidence coverage B (3 of 5 independent signal types). The public evidence: no package-provenance attestation found; no OSSF Scorecard result yet; 100% of recent commits are signed; no published advisory affects its latest release (trulens-core); last pushed 2026-10-09. Every point is earned from checkable signals — never paid placement. How scoring works →
How TruLens 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 TruLens 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 Signed
github.com/truera/trulens, MIT, last pushed 2026-10-09. 100% of the last 100 commits carry a verified signature, so changes trace to a verified account.
-
Review and release Not checked
No OpenSSF Scorecard result yet, so branch protection, code review and release signing are unverified.
-
Published packages Linked, not attested
- PyPI trulens-core Source link points back to this repo No build attestation
Without a build attestation, nothing proves the published files were built from this repository.
-
What you install today No known advisories
Latest release checked: trulens-core 2.15.0. No published advisory affects it (OSV, checked 2026-10-09).
Changes to this chain
No change to package provenance, package source links, Scorecard coverage or license in HVTracker's daily snapshots of TruLens.

Verify this score yourself
Every build re-issues TruLens’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 D 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 →

Does TruLens publish package provenance?
Does TruLens have an OpenSSF Scorecard?
Is TruLens actively maintained?
What license does TruLens use?
Are TruLens'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.

Maintain TruLens?
For maintainers
HVTrust scores TruLens 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.
