## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 13 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 0.9.1
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

The source sends an OwlMem token to OwlMem's own service by default and gates vault-backed command execution behind a tool call. The command entry point runs only when invoked, and the reviewed network and execution behavior matches the package's stated purpose.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 97.0%

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** No attack was identified; the package provides an OwlMem vault CLI and local MCP server.

- **Trigger:** CLI commands run when invoked; MCP behavior requires starting the server and receiving a tool call.

- **Impact:** The reviewed behavior matches the package's stated vault and AI integration purpose.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-31T01:02:50.677Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The CLI contacts OwlMem or the configured OWLMEM\_URL using its OwlMem token. Vault-backed command execution is exposed as a tool and masks matching secret values in captured output.

- **Rationale:** The source sends an OwlMem token to OwlMem's own service by default and gates vault-backed command execution behind a tool call. The command entry point runs only when invoked, and the reviewed network and execution behavior matches the package's stated purpose.

- **Files touched:** owlmem.mjs, package.json

- **Network endpoints:** https://owlmem.com, OWLMEM\_URL (configurable base URL)

### Review decision

- **Verdict:** Clean

- **Confidence:** 97.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The manifest describes OwlMem as an AI-agent vault CLI and declares owlmem.mjs as its command entry point., Network requests use the OwlMem service by default; the base URL can be set with OWLMEM\_URL., The CLI sends its OwlMem token to that configured base URL for vault requests., Vault command execution receives secrets only through an explicit vault\_run tool call; command output is masked against those secrets., The CLI runs only when invoked as a command, rather than starting its main routine on import.
