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:** 0.84.0 - **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. The package has a real high-impact browser and agent capability, so it warrants a warning. The observed behavior is user-invoked and package-aligned, with no concrete malicious install-time or covert attack chain. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 83.0% - **Started:** 2026-09-01T13:12:52.783Z - **Finished:** 2026-09-01T13:14:15.865Z - **Download time:** 256 ms - **Static scan time:** 25347 ms - **AI review time:** 57476 ms - **Total time:** 83082 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:** When explicitly configured and invoked, the MCP server sends its configured API key to its hosted service and can operate browser sessions with persisted profile state. There is no automatic install-time activation. - **Trigger:** The user starts the MCP server, invokes its browser tools, or runs the CLI agent install command with --apply. - **Impact:** A user who grants the server access to an authenticated browser profile can expose that session to the package's hosted browser workflow. - **Evidence paths:** dist/chunk-WDWWCNMW.js, dist/bin/mcp-scraper-cli.js, dist/server-3F3JMHBF.js - **Review source:** ai\_review - **Reviewed:** 2026-09-01T13:14:15.865Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Hosted MCP calls and browser-session automation using a user-provided API key. - **Rationale:** The package has a real high-impact browser and agent capability, so it warrants a warning. The observed behavior is user-invoked and package-aligned, with no concrete malicious install-time or covert attack chain. - **Files touched:** ~/.mcp-scraper-key, Claude Code user-scope MCP configuration - **Network endpoints:** https://mcpscraper.dev/mcp ### Review decision - **Verdict:** Suspicious - **Confidence:** 83.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The MCP runtime reads an API key and sends it to the package service for tool calls., An explicit CLI command can register a user-scope Claude Code MCP server and optionally preserve browser profile state., The bundled server implements hosted browser sessions capable of operating with saved profiles and authenticated web sessions. - **Evidence against:** package.json has no preinstall, install, postinstall, or prepare lifecycle hook., Agent configuration changes require the user to run the CLI with --apply; only Claude Code is supported., The service endpoint defaults to the package's own mcpscraper.dev domain; no covert foreign endpoint or payload loading was found. ## Affected versions and remediation This report applies to mcp-scraper@0.84.0. - Review the evidence and your use of mcp-scraper@0.84.0 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.
