In detail: Microsoft Agent Framework scores 72.2/100 (Grade B), ranked #295 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; OSSF Scorecard rates its supply-chain practices 5.8/10; 100% of recent commits are signed; no published advisory affects its latest release (agent-framework); last pushed 2026-10-08. Every point is earned from checkable signals — never paid placement. How scoring works →

How Microsoft Agent Framework 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 Microsoft Agent Framework 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.

  1. Source Signed

    github.com/microsoft/agent-framework, MIT, last pushed 2026-10-08. 100% of the last 100 commits carry a verified signature, so changes trace to a verified account.

  2. Review and release Mixed

    OpenSSF Scorecard rates the repository's practices 5.8/10 (scanned Oct 7, 2026). The checks that decide who can get a change released:

  3. Published packages Not linked

    • PyPI agent-framework Source link isn't a GitHub repo No build attestation

    Without a build attestation, nothing proves the published files were built from this repository.

  4. What you install today No known advisories

    Latest release checked: agent-framework 1.21.0. 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 Microsoft Agent Framework.

Evidence behind this score

Coverage B: 3 of 5 independent evidence types found.

  • GitHub repository data
  • Package downloads
  • Supply-chain checks
  • Public actions (missing)
  • Community mentions (missing)

Verify this score yourself

Every build re-issues Microsoft Agent Framework’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 Agent Frameworks

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 Microsoft Agent Framework

Microsoft Agent Framework 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 Microsoft Agent Framework publish package provenance?
No published build provenance is currently detected for Microsoft Agent Framework. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.
Does Microsoft Agent Framework have an OpenSSF Scorecard?
Microsoft Agent Framework 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 Microsoft Agent Framework actively maintained?
Actively maintained. The repository was pushed to within the last 1 day(s).
What license does Microsoft Agent Framework use?
Microsoft Agent Framework ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are Microsoft Agent Framework's commits signed?
100% of the last 100 commits to Microsoft Agent Framework 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 Microsoft Agent Framework?

For maintainers

HVTrust scores Microsoft Agent Framework 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.
