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:** 0.46.0 - **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 chain was found, but the package exposes high-impact authenticated browser automation to MCP tool callers. Its explicit Claude registration mutation is user-command gated and scoped to its own entry. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-08-09T01:20:14.810Z - **Finished:** 2026-08-09T01:21:18.604Z - **Download time:** 1017 ms - **Static scan time:** 25122 ms - **AI review time:** 37652 ms - **Total time:** 63794 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:** At runtime, the MCP server can operate hosted browsers with user-created authenticated profiles and issue actions through MCP tools. No install-time execution or unconsented configuration mutation is present. - **Trigger:** A user installs/configures the MCP server, authenticates a hosted profile, then invokes browser or workflow tools. - **Impact:** An authorized but over-privileged agent/tool caller could act through a saved third-party web session. - **Evidence paths:** package.json, dist/bin/mcp-scraper-cli.js, dist/bin/mcp-stdio-server.js, dist/chunk-BP2IUIAH.js, dist/chunk-QSUGPYGQ.js - **Review source:** ai\_review - **Reviewed:** 2026-08-09T01:21:18.604Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Authenticated hosted-browser automation and explicit Claude MCP registration. - **Rationale:** No concrete malicious chain was found, but the package exposes high-impact authenticated browser automation to MCP tool callers. Its explicit Claude registration mutation is user-command gated and scoped to its own entry. - **Files touched:** ~/.mcp-scraper-key, ~/Downloads/mcp-scraper - **Network endpoints:** https://mcpscraper.dev, https://registry.npmjs.org/mcp-scraper/latest ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** dist/chunk-BP2IUIAH.js exposes hosted browser sessions using saved authenticated profiles., browser\_profile\_connect directs users to sign in to arbitrary domains including ChatGPT and Claude, then reuses that profile., query\_fanout\_workflow can submit a real message in the logged-in account when given a prompt., dist/bin/mcp-scraper-cli.js can alter the Claude user-scope MCP registration, but only after explicit agent install claude --apply. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., Agent configuration mutation is explicitly gated by --apply and limited to its mcp-scraper entry., Profile setup states existing cookies are not imported and the user signs in fresh., Network calls use configured API credentials and package-aligned mcpscraper.dev endpoints; no covert exfiltration was found. ## Affected versions and remediation This report applies to mcp-scraper@0.46.0. - Review the evidence and your use of mcp-scraper@0.46.0 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.
