@echomem/mcp@1.4.9
EchoMem MCP bridge: cloud-first memory tools, local context HUD, and the Agent Doctor workspace forensics report (cost ledger + 3D repo city)
AI Security Review
scanned 3mo ago · by lpm-firewall-aiSource inspection found no malicious install-time behavior, but it provides user-invoked mutations of global AI-agent configuration and guidance. Flag as a warning for this capability rather than block it.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
User runs echomem-mcp setup/init or echomem-hud install-hooks/autostart on
Impact
Can cause configured agents to invoke EchoMem and can persist the optional local HUD.
Mechanism
User-invoked AI-agent configuration, hook, and HUD persistence setup
AI rationale
Source inspection found no malicious install-time behavior, but it provides user-invoked mutations of global AI-agent configuration and guidance. Flag as a warning for this capability rather than block it.

Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- dist/setup.js: explicit setup/init writes MCP entries and global agent guidance
- dist/setup.js: guidance tells Codex/Claude to call EchoMem memory tools
- dist/hud/hooks.js: explicit install-hooks writes ~/.codex/hooks.json commands
- dist/hud/autostart.js: explicit CLI action creates a macOS LaunchAgent
Evidence against
- package.json has no preinstall/install/postinstall lifecycle hook
- dist/setup.js gates configuration writes behind setup/init commands
- dist/hud/cli.js gates hooks and autostart behind named user commands
- dist/index.js sends MCP memory requests to the documented EchoMem API with its stored token
- dist/keystore.js stores credentials locally with restrictive modes
