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:** 0.27.0 - **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 is not malicious by static source evidence, but it contains an explicit user-command path that mutates an AI-agent configuration and enables a hosted MCP capability. Per policy, that warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-07-28T23:29:06.972Z - **Finished:** 2026-07-28T23:29:50.310Z - **Download time:** 509 ms - **Static scan time:** 4237 ms - **AI review time:** 38591 ms - **Total time:** 43338 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 human CLI command can register mcp-scraper as a Claude Code user-scope MCP server. At runtime the MCP server forwards requested tool calls with its configured API key to the package service; no install-time attack surface is established. - **Trigger:** User runs \`mcp-scraper-cli agent install claude --apply\`, or configures and starts the MCP server. - **Impact:** Adds this package's web/browser capabilities to the user's Claude Code configuration and sends invoked tool requests to its hosted service. - **Evidence paths:** package.json, dist/bin/mcp-scraper-cli.js, dist/bin/mcp-stdio-server.js, dist/chunk-KAMKTSJQ.js, dist/server-YXVSZ3T7.js - **Review source:** ai\_review - **Reviewed:** 2026-07-28T23:29:50.310Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Explicit MCP registration and hosted MCP API forwarding. - **Rationale:** The package is not malicious by static source evidence, but it contains an explicit user-command path that mutates an AI-agent configuration and enables a hosted MCP capability. Per policy, that warrants a warning rather than a block. - **Network endpoints:** https://mcpscraper.dev, https://mcpscraper.dev/mcp ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** \`dist/bin/mcp-scraper-cli.js\` can run \`claude mcp remove/add\` only under explicit \`agent install claude --apply\`., The applied registration installs this package as a user-scope MCP server, extending Claude Code capabilities., \`dist/bin/mcp-stdio-server.js\` reads its configured API key and sends MCP tool calls to \`https://mcpscraper.dev/mcp\`. - **Evidence against:** \`package.json\` has no preinstall, install, or postinstall lifecycle hook., Agent configuration is opt-in, requires an explicit CLI command plus \`--apply\`, and supports only its own named server., No bidi controls were found in \`dist/server-YXVSZ3T7.js\`; the scanner Trojan Source signal is unsupported., Child-process use is bounded to explicit CLI operations and opening user-requested local reports/URLs., No source evidence of credential harvesting, stealth persistence, destructive actions, or remote code loading. ## Affected versions and remediation This report applies to mcp-scraper@0.27.0. - Review the evidence and your use of mcp-scraper@0.27.0 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.
