EchoMem MCP bridge for cross-agent memory, local history import, and recall
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe package has no install lifecycle scripts, and its self-runtime installation explicitly uses npm with scripts disabled. Agent hooks and configuration changes are reachable through explicit setup commands rather than package installation.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Explicit CLI setup or authenticated HUD use.
Impact
No unconsented persistence or data exfiltration was confirmed.
Mechanism
User-invoked local configuration and memory synchronization.
AI rationale
The package has no install lifecycle scripts, and its self-runtime installation explicitly uses npm with scripts disabled. Agent hooks and configuration changes are reachable through explicit setup commands rather than package installation.
Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest has no install lifecycle hook; it exposes a CLI entry point.
- Configuration writes are reached only through explicit init, setup, or update commands.
- The durable runtime installer fetches this package by exact version with lifecycle scripts disabled.
- Durable re-execution occurs only when an explicit configuration command runs from an npx cache.
- Hook configuration is installed by setup logic and targets EchoMem commands.
- The HUD binds locally and sends session content only through its authenticated renewal action.
Evidence against
- No package-install-time execution or unconsented agent-control-surface mutation was found.
- No credential harvesting, arbitrary command execution, or stealthy exfiltration path was confirmed.
