In detail: FreeCAD MCP scores 56.1/100 (Grade C), ranked #805 of 1378 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 5.7/10; recent commits are unsigned; last pushed 2026-10-13. Every point is earned from checkable signals — never paid placement. How scoring works →

How FreeCAD 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 FreeCAD MCP 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 Unsigned

github.com/blwfish/freecad-mcp, LGPL-2.1, last pushed 2026-10-13. None of the last 100 commits carry a verified signature, so no change traces to a verified identity.
Review and release Mixed

OpenSSF Scorecard rates the repository's practices 5.7/10 (scanned Oct 17, 2026). The checks that decide who can get a change released:

Verify this score yourself

Every build re-issues FreeCAD 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 C 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 →

Common questions about FreeCAD MCP

FreeCAD 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 FreeCAD MCP publish package provenance?

No published build provenance is currently detected for FreeCAD MCP. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.

Does FreeCAD MCP have an OpenSSF Scorecard?

FreeCAD MCP has an OpenSSF Scorecard score of 5.7/10. 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 FreeCAD MCP actively maintained?

Actively maintained. The repository was pushed to within the last 5 day(s).

What license does FreeCAD MCP use?

FreeCAD MCP ships under LGPL-2.1. A declared, OSI-approved license is one of the transparency signals HVTrust scores.

Are FreeCAD MCP's commits signed?

0% of the last 100 commits to FreeCAD 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.

Maintain FreeCAD MCP?

For maintainers

HVTrust scores FreeCAD MCP 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.
