E critical
  • vulnerabilities attested + 50
  • capability exposure inferred + 35

attested inferred

The A–E grade is our heuristic synthesis — a "review this" prompt, not a verdict. Each factor is tagged by what backs it: attested (a verifiable record), reported (a third party's claim), or inferred (our own heuristic, e.g. permissions). See methodology.

CRITICAL
Inspector proxy server vulnerabilities EPSS 3% CVE-2025-49596 affects ["< 0.14.1"]
HIGH
Potential Command Execution in MCP Inspector via XSS When Connecting to an Untrusted MCP Server EPSS 0% CVE-2025-58444 affects ["< 0.16.6"]
tool safety all quiet

No tool-safety findings — heuristic detectors run on the compute-risk cadence; a finding appears when a tool trips a rule.

Heuristic, inferred signals — false positives (legitimately powerful tools, forks, language ports) are expected. Treat each as "review this", not a verdict. See the ecosystem-wide picture on the security hub, or the fleet security of modelcontextprotocol.
