## Verdict summary
**Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only AI-agent capability risk
- **Public report status:** Published
- **Threat category:** AI-agent capability abuse
- **Selected version:** 0.89.0
- **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

No concrete malicious install-time behavior or secret exfiltration was established by source inspection. The explicit agent configuration mutation and floating runtime package reference are still a meaningful capability risk.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 82.0%
- **Started:** 2026-09-05T04:01:26.007Z
- **Finished:** 2026-09-05T04:04:19.165Z
- **Download time:** 252 ms
- **Static scan time:** 22644 ms
- **AI review time:** 150261 ms
- **Total time:** 173158 ms

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:** An explicit CLI option can replace the user's Claude Code MCP registration with an entry that runs this package through npx. No automatic install-time execution or unconsented configuration mutation was found.

- **Trigger:** A user runs mcp-scraper-cli agent install claude with --apply.

- **Impact:** The user's Claude Code configuration can be changed to launch the package, and later launches may resolve a newer release.

- **Evidence paths:** dist/bin/mcp-scraper-cli.js, dist/server-RFR2A5UJ.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-05T04:04:19.165Z

### AI review details

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

- **Mechanism:** Explicit Claude Code MCP registration using a floating npx package spec.

- **Rationale:** No concrete malicious install-time behavior or secret exfiltration was established by source inspection. The explicit agent configuration mutation and floating runtime package reference are still a meaningful capability risk.

- **Files touched:** dist/bin/mcp-scraper-cli.js

- **Network endpoints:** https://mcpscraper.dev/mcp

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 82.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** The CLI has an explicit --apply path that changes a Claude Code MCP registration., That registration defaults to a floating mcp-scraper@latest package spec., The bundled server exposes a configuration template that places an API-key environment reference in an MCP client configuration.

- **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., The configuration-changing path requires an explicit CLI command and --apply flag., The observed API endpoint is the package's own mcpscraper.dev service; no unrelated credential-exfiltration endpoint was confirmed.

## Affected versions and remediation

This report applies to mcp-scraper@0.89.0.

- Review the evidence and your use of mcp-scraper@0.89.0 before allowing it. Restrict the permissions described in this report.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
