hippo-memory@1.52.8

Memory for AI agents that learns what is wrong and stops repeating it. MCP server and hooks for Claude Code, Codex and Cursor. SQLite, zero runtime deps.

AI Security Review

scanned 14d ago · by lpm-firewall-ai

Inspected source shows a guarded, repair-only postinstall path and CLI-exposed agent integration. The static warnings do not establish malicious behavior.

Static reason

One or more suspicious static signals were detected.

Trigger

Package installation invokes the postinstall wrapper; CLI commands can explicitly install agent integrations.

Impact

No unconsented broad agent configuration mutation, credential exfiltration, or other concrete attack behavior was established.

Mechanism

Postinstall calls a repair routine that requires existing wrapper metadata. The inspected integration declarations expose install and uninstall functions.

AI rationale

Inspected source shows a guarded, repair-only postinstall path and CLI-exposed agent integration. The static warnings do not establish malicious behavior.

Decision evidence

public snapshot

AI called this Clean at 89.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The postinstall entry invokes a small wrapper that imports the compiled postinstall module.
The postinstall module attempts wrapper repair; repair returns without changing anything when no prior wrapper metadata exists.
Repair is limited to an existing opted-in Codex wrapper, while integration installation is exposed through the CLI.
Capture code reads the user's Claude project directory as local input; inspected code shows no network send there.
The embedding provider uses an API-backed embedding path, consistent with the package's stated embedding functionality.
