## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 10 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:** 0.3.4
- **Selected version is latest:** Yes
- **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 package has no install hook in its manifest, and its runtime source implements caller-directed storage operations using the Google Cloud Storage client. The inspected dependency entrypoints expose the expected storage API; no independent attack behavior was found.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 94.0%

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 in the inspected package source. It provides filesystem operations backed by Google Cloud Storage.

- **Trigger:** A caller constructs or uses the exported filesystem provider.

- **Impact:** Operations affect the configured storage bucket; the inspected source shows no separate collection or transmission of credentials.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-21T12:04:58.227Z

### AI review details

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

- **Mechanism:** The adapter passes caller-supplied credentials and an optional endpoint to the Google Cloud Storage client for bucket operations.

- **Rationale:** The package has no install hook in its manifest, and its runtime source implements caller-directed storage operations using the Google Cloud Storage client. The inspected dependency entrypoints expose the expected storage API; no independent attack behavior was found.

### Review decision

- **Verdict:** Clean

- **Confidence:** 94.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The package manifest exposes a Google Cloud Storage filesystem and its scripts contain no preinstall, install, or postinstall hook., The filesystem takes credentials and an optional API endpoint from caller-provided options, then passes them to the Google Cloud Storage client., The inspected dependency manifest identifies the expected Google Cloud Storage client; its prepare script runs compilation., The dependency’s CommonJS and ESM entrypoints export the Storage client and related storage modules.

## Affected versions and remediation

This report applies to @mastra/gcs@0.3.4.

- Review the evidence and your use of @mastra/gcs@0.3.4 before allowing it. Restrict the permissions described in this report.
