StatusCheckPolicyResult
PASS Listed on the official MCP registry §1.1
Listed on registry.modelcontextprotocol.io as ai.certscore/mcp. 1 finding
  • Registry entry: ai.certscore/mcp ↗
WARN Source repository is public and maintained §1.2
Repository health issues: no license. 5 findings
  • Repository ↗
  • Last push: 0 days ago
  • Stars: 0
  • License: none detected
  • Security policy (SECURITY.md): absent
WARN Published package is consistent and attested §1.3
Minor integrity gaps: package is only 22 days old; no npm provenance attestation. 6 findings
  • Package: @certscore/mcp@0.2.12 ↗
  • Ecosystem: npm
  • Age: 22 days
  • Weekly downloads: 149
  • Repo field matches source repo: true
  • Build-provenance attestation: absent
PASS Tool surface is inspectable and proportionate §2.1–§2.4
Package source scanned. Capabilities detected: filesystem, process-execution, network-egress. Reported as capability risk (§2.4); whether each is essential to the server's stated purpose is §2.3 and remains a manual judgement. 6 findings
  • filesystem (filesystem write/delete): dist/index.js
  • filesystem (fs module import): dist/index.js
  • filesystem (fs module import): dist/version.js
  • process-execution (dynamic code evaluation): dist/certscore-mcp.mjs
  • network-egress (outbound network calls): dist/certscore-mcp.mjs
  • Detected capabilities: filesystem, process-execution, network-egress
INFO Transport & authentication §3

Local (stdio) server: runs with host-process privileges by design. Transport checks apply to remote servers; scrutiny shifts to §1/§2.
PASS No known vulnerabilities (OSV.dev) §4.1

No advisories on record for @certscore/mcp @0.2.12 (npm).
PASS Server-supplied instructions free of poisoning indicators §5.1–§5.4

No poisoning indicators found across 14 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.
