EchoMem MCP bridge: cloud-first memory tools and the Agent Doctor workspace forensics report (cost ledger + 3D repo city)
AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a confirmed, user-triggered first-party agent-extension lifecycle risk rather than install-time malware. The persistent global control-surface writes and completion-blocking hook warrant a warning.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
User runs echomem-mcp init/setup/migrate.
Impact
Persistent cross-session agent steering and user transcript upload capability.
Mechanism
global agent configuration and hook installation with cloud memory sync
AI rationale
This is a confirmed, user-triggered first-party agent-extension lifecycle risk rather than install-time malware. The persistent global control-surface writes and completion-blocking hook warrant a warning.

Decision evidence
public snapshotAI called this Suspicious at 96.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- dist/setup.js: init configures all detected agents and installs save hooks by default.
- dist/setup.js writes global ~/.codex/AGENTS.md and ~/.claude/CLAUDE.md guidance favoring EchoMem.
- dist/hud/hooks.js adds Codex/Claude Stop hooks that run package code.
- dist/save-checkpoint-hook.js can block completion to require save_conversation.
- dist/migrate.js uploads local Codex/Claude transcript text when migrate is invoked.
Evidence against
- package.json has no preinstall, install, or postinstall hook.
- Config, hooks, skills, and migration run only through explicit CLI setup/init/migrate commands.
- dist/setup.js documents explicit consent before its onboarding local-history scan.
- Network use is package-aligned EchoMem API traffic with stored user token.
