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 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 JustCall MCP Server safe?

Public trust evidence for JustCall MCP Server 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 JustCall MCP Server publish package provenance?

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

Does JustCall MCP Server have an OpenSSF Scorecard?

JustCall MCP Server has an OpenSSF Scorecard score of 4.0/10. 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 JustCall MCP Server actively maintained?

Slowing down. Last push was 180 days ago — keep an eye on whether activity resumes.

What license does JustCall MCP Server use?

JustCall MCP Server ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.

Are JustCall MCP Server's commits signed?

96% of the last 100 commits to JustCall MCP Server 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.
