Maintainer Checklist
Raise Scorecard signalsCurrent OSSF Scorecard is 3.9/10. Tighten the weakest checks to improve public safety evidence.
Publish provenanceAdd package provenance or release attestations so users can verify where shipped artifacts came from.
Increase signed commitsRaise the share of verified-signed commits to make maintainer identity and release history easier to trust.
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 Perplexity MCP Server safe?
Public trust evidence for Perplexity 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 Perplexity MCP Server publish package provenance?
No published build provenance is currently detected for Perplexity 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 Perplexity MCP Server have an OpenSSF Scorecard?
Perplexity MCP Server has an OpenSSF Scorecard score of 3.9/10. 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 Perplexity MCP Server actively maintained?
Maintained. Last push was 26 days ago.
What license does Perplexity MCP Server use?
Perplexity MCP Server ships under no SPDX license detected. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
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 Perplexity MCP Server?
HVTrust scores Perplexity MCP Server 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.
