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.

No known CVEs for this server.
- high dangerous code
committed secret: private key · dynamic exec: __import__ sink
- medium toxic flow (lethal trifecta)
lethal trifecta reachable across connected servers: this server can exfiltrate (network) while a connected dependency supplies private-data access / untrusted-content ingestion
- low exfiltration combo
sensitive read and network capabilities split across this server's tools

[](https://mcpobservatory.com/servers/github:willow-memory/willow-mcp/security) 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 willow-memory.
