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 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 →

Is FastMCP safe?
Public trust evidence for FastMCP is thin: several supply-chain signals are missing or weak. This does not mean the project is unsafe — it means an outside observer cannot easily verify the usual integrity checks. Treat with extra scrutiny.
Does FastMCP publish package provenance?
No published build provenance is currently detected for FastMCP. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.
Does FastMCP have an OpenSSF Scorecard?
FastMCP has an OpenSSF Scorecard score of 5.5/10. 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 FastMCP actively maintained?
Actively maintained. The repository was pushed to within the last 4 day(s).
What license does FastMCP use?
FastMCP ships under Apache-2.0. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are FastMCP's commits signed?
100% of the last 100 commits to FastMCP 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.
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.

Maintain FastMCP?
HVTrust scores FastMCP 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.
