EchoMem MCP bridge for cross-agent memory, local history import, and recall
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThis package contains broad but product-aligned MCP memory and local-session features. It has no npm install lifecycle hook, and its self-staging update path explicitly disables lifecycle scripts.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Running the MCP bridge, or explicitly running its setup command with hook installation.
Impact
Normal product operations can access configured memory data and locally tracked sessions; no unconsented install-time action was found.
Mechanism
MCP memory service, optional agent hooks, and managed runtime updates.
AI rationale
This package contains broad but product-aligned MCP memory and local-session features. It has no npm install lifecycle hook, and its self-staging update path explicitly disables lifecycle scripts.

Decision evidence
public snapshotAI called this Clean at 84.0% confidence as Benign with medium false-positive risk.
Evidence for AI clean decision
- The manifest exposes a CLI but no install lifecycle hook.
- The running bridge can stage a newer release of itself through npm after an update check.
- Explicit setup can add command hooks to Codex configuration.
- The source-session feature reads local Codex session metadata.
- The local HUD can serve tracked raw session files.
Evidence against
- The self-install command uses npm's ignore-scripts option, so it does not trigger nested package lifecycle scripts.
- Hook installation is tied to setup options and names the installed hooks; it is not an npm install-time action.
- The HUD validates requested paths against its tracked-session list.
- No credential harvesting, secret exfiltration, opaque payload, or destructive behavior was found.
