PASS HTTPS-only endpoint §3.1
Endpoint uses HTTPS. 1 finding
  • Endpoint: https://mcp.cleanor.app/mcp
UNVERIFIABLE Authentication required §3.2

Endpoint rejected the probe (HTTP 400); whether it requires authentication could not be determined.

PASS Server-supplied instructions free of poisoning indicators §5.1–§5.4

No poisoning indicators found across 45 server-supplied text item(s).
What this grade covers
  • Provenance & supply-chain integrity (§1)
  • Tool surface & capability risk (§2)
  • Transport & authentication (§3)
  • Known CVEs via OSV.dev (§4)
  • Instruction/tool poisoning patterns (§5)

Limitations: pattern-based only (no semantic injection detection), static npm analysis (live server instructions not retrieved for package-only scans), single-server scope (no cross-server toxic flow analysis). See the full policy.
