100/100 integrity 100% evidence coverage evidence-backed Measures evidence support, not confidence — how this is scored

Verdict (the facts)

Tool
npm/@modelcontextprotocol/server-memory
Integrity axis
honest — Observed behaviour matches its description; no undisclosed recipient.
Data-flow axis
No network egress to external destinations was observed — the tool ran purely locally.
Disclosure
n/a — No external egress was observed; there is nothing to disclose.
Capture self-test
verified
Severity
none — integrity axis (no undeclared exfiltration; no egress at all).

Residual gap

How we know this — claims by basis

Observed — directly in the capture, reproducible

Classified — our adversarially-reviewed judgment

Method

Installed and run in an isolated container; fed traceable decoy data; all outbound traffic intercepted (TLS broken via own CA, iptables transparent redirect). A beacon self-test confirmed the capture was live.

Scope

Compares the tool's declared destinations against what was observed in one sandbox run. Checks transparency / integrity for a cooperative tool, NOT resistance to deliberate evasion. "honest"/"clean" means "observed without deviation within our reach", NOT "guaranteed no hidden egress". Out of scope: exfiltration split/chunked across requests; tool-side encryption of the payload before egress; input/time/state-triggered processing not triggered in the run.
