Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## 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:** 0.90.4 - **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. The explicit AI-agent configuration mutation is a dangerous capability that warrants a warning under policy. It is not malicious because the source requires an explicit CLI action and no automatic attack behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-22T14:15:36.428Z - **Finished:** 2026-09-22T14:17:03.670Z - **Download time:** 510 ms - **Static scan time:** 14237 ms - **AI review time:** 72494 ms - **Total time:** 87242 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 command can register this package as a Claude Code MCP server. No automatic install-time attack was identified. - **Trigger:** A user runs mcp-scraper-cli agent install with --apply for Claude Code. - **Impact:** This changes an AI-agent control surface only after explicit user invocation; no confirmed covert attack surface was established. - **Evidence paths:** dist/bin/mcp-scraper-cli.js - **Review source:** ai\_review - **Reviewed:** 2026-09-22T14:17:03.670Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI invokes Claude Code commands to replace or add the mcp-scraper user-scope server configuration. - **Rationale:** The explicit AI-agent configuration mutation is a dangerous capability that warrants a warning under policy. It is not malicious because the source requires an explicit CLI action and no automatic attack behavior was found. ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The CLI contains an explicit agent-install command that can apply a user-scope Claude Code MCP configuration., Package metadata exposes the CLI as a user-invoked binary. - **Evidence against:** package.json contains no preinstall, install, postinstall, or prepare lifecycle hook., The configuration action is gated by the explicit --apply option and is limited to Claude Code. ## Affected versions and remediation This report applies to mcp-scraper@0.90.4. - Review the evidence and your use of mcp-scraper@0.90.4 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. ## Public findings ### 1.
