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:** 0.51.0 - **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. This is not malware, but it ships high-impact AI-agent browser control and an explicit agent-config mutation path. Warn so users can assess capability grants and authenticated-profile use. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-08-09T13:56:34.922Z - **Finished:** 2026-08-09T13:58:20.522Z - **Download time:** 251 ms - **Static scan time:** 29273 ms - **AI review time:** 76074 ms - **Total time:** 105600 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:** The package exposes an MCP browser-control capability that can operate sites authenticated through user-created hosted profiles. Its CLI can explicitly register its own Claude MCP server entry; no automatic install-time control-surface mutation exists. - **Trigger:** User runs the MCP server/browser tools or explicitly invokes \`mcp-scraper-cli agent install claude --apply\`. - **Impact:** An AI client granted these tools could interact with authenticated web accounts; configuration changes are limited to the package's own Claude entry. - **Evidence paths:** package.json, dist/bin/mcp-scraper-cli.js, dist/chunk-O63VVCCE.js, dist/bin/mcp-stdio-server.js - **Review source:** ai\_review - **Reviewed:** 2026-08-09T13:58:20.522Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Authenticated browser automation and explicit same-entry MCP registration. - **Rationale:** This is not malware, but it ships high-impact AI-agent browser control and an explicit agent-config mutation path. Warn so users can assess capability grants and authenticated-profile use. - **Network endpoints:** https://mcpscraper.dev ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** dist/bin/mcp-scraper-cli.js: --apply explicitly removes and re-adds its Claude user-scope MCP entry., dist/chunk-O63VVCCE.js: browser tools retain user-created authenticated profiles and can navigate, read, click, type, and press keys., dist/chunk-O63VVCCE.js: browser tools send authenticated API requests to the configured MCP Scraper service. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., Agent configuration mutation is gated behind the explicit \`agent install claude --apply\` command and targets only \`mcp-scraper\`., Profile login is an interactive user flow; existing local browser cookies are stated not to be imported., No source evidence of secret harvesting, stealth exfiltration, remote code loading, or destructive install-time behavior. ## Affected versions and remediation This report applies to mcp-scraper@0.51.0. - Review the evidence and your use of mcp-scraper@0.51.0 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. ## Public findings ### 1.
