EchoMem MCP bridge for cross-agent memory, local history import, and recall
AI Security Review
scanned 19d ago · by lpm-firewall-aiStatic hints were verified against source: the package has no npm lifecycle hook, and the agent configuration changes occur through setup behavior. Inspected network and session-discovery code is consistent with the stated EchoMem integration, with no concrete attack behavior found.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Agent configuration and hooks are written during an explicit setup command; runtime server behavior begins when the MCP entrypoint is launched.
Impact
No confirmed unauthorized credential transfer, unconsented install-time control-surface change, or other attack effect was established.
Mechanism
The reviewed code locates local agent session data and integrates EchoMem guidance, skills, and hooks into detected agent configuration. Setup requests use the EchoMem API base URL.
AI rationale
Static hints were verified against source: the package has no npm lifecycle hook, and the agent configuration changes occur through setup behavior. Inspected network and session-discovery code is consistent with the stated EchoMem integration, with no concrete attack behavior found.

Decision evidence
public snapshotAI called this Clean at 88.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json declares no preinstall, install, or postinstall hook; its runtime entry is dist/index.js.
- The scorer assets locate and count turns in local Codex session files; the inspected paths show local session discovery.
- The HUD monitor reads Codex session index metadata to detect changes.
- Migration code identifies Claude session files under the local Claude projects directory.
- Setup resolves the Claude configuration directory and runs agent guidance, skill, and hook setup as part of the explicit setup flow.
- The durable runtime installs this package version for an ephemeral npx invocation; this is runtime setup, not a package lifecycle hook.
- The setup client uses the EchoMem API base URL for authenticated requests, consistent with the package's stated service.
