In Protocols & Tool Integration

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 →

Is Microsoft MCP Catalog safe?

Microsoft MCP Catalog 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 MCP Catalog publish package provenance?
No published build provenance is currently detected for Microsoft MCP Catalog. 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 MCP Catalog have an OpenSSF Scorecard?
Microsoft MCP Catalog has an OpenSSF Scorecard score of 6.8/10. 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 MCP Catalog actively maintained?
Actively maintained. The repository was pushed to within the last 1 day(s).
What license does Microsoft MCP Catalog use?
Microsoft MCP Catalog ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are Microsoft MCP Catalog's commits signed?
100% of the last 100 commits to Microsoft MCP Catalog 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.
