EchoMem MCP bridge for cross-agent memory, local history import, and recall
AI Security Review
scanned 19d ago · by lpm-firewall-aiThe manifest has no npm install lifecycle hook, and inspected runtime behaviors are tied to EchoMem functionality or explicit setup. The scanner’s flagged locations did not establish a concrete attack surface.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
The CLI or MCP runtime is run; agent hooks are added only through explicit hook installation functions.
Impact
No confirmed unauthorized configuration change, credential disclosure, or other attack effect was established.
Mechanism
The source reads local agent session data, adds EchoMem callbacks to user settings when installation functions run, and stages runtime updates with npm scripts disabled.
AI rationale
The manifest has no npm install lifecycle hook, and inspected runtime behaviors are tied to EchoMem functionality or explicit setup. The scanner’s flagged locations did not establish a concrete attack surface.
Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json defines the CLI entry point and ordinary development scripts, with no install lifecycle hook.
- The flagged asset and migration code reads local agent session indexes and transcript paths as part of its product functionality.
- HUD hooks are installed through explicit functions and add EchoMem callbacks to user settings.
- Runtime updates install the requested EchoMem version into managed staging with npm scripts disabled.
- The default API endpoint is EchoMem’s service; the bearer token is sent through a client configured for that API base.
