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 malicious install hook, concealed exfiltration, or autonomous persistence was found. The explicit user-command Claude MCP mutation is a meaningful agent-extension risk and warrants a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-08-28T01:04:45.632Z - **Finished:** 2026-08-28T01:06:18.421Z - **Download time:** 282 ms - **Static scan time:** 31595 ms - **AI review time:** 60910 ms - **Total time:** 92789 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 can explicitly register itself as a Claude Code MCP server and then exposes hosted browser, scheduling, and memory capabilities. No install-time attack surface was found. - **Trigger:** The user runs mcp-scraper-cli agent install claude --apply, then starts the configured MCP server. - **Impact:** A user-approved agent configuration gains this package's broad advertised MCP capabilities and access to its API key. - **Evidence paths:** package.json, dist/bin/mcp-scraper-cli.js, dist/bin/mcp-stdio-server.js - **Review source:** ai\_review - **Reviewed:** 2026-08-28T01:06:18.421Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Explicit Claude MCP registration and authenticated hosted tool access. - **Rationale:** No malicious install hook, concealed exfiltration, or autonomous persistence was found. The explicit user-command Claude MCP mutation is a meaningful agent-extension risk and warrants a warning. - **Files touched:** ~/.mcp-scraper-key - **Network endpoints:** https://mcpscraper.dev ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** An explicit CLI option can replace the user's Claude Code MCP entry with this package., The MCP server reads an API key from environment variables or a package-specific home-directory file., The configured server registers browser, scheduling, and memory tools. - **Evidence against:** package.json has no install lifecycle hook., The Claude configuration change requires the user to run the CLI with --apply., The default network service is the package's documented mcpscraper.dev endpoint., No source evidence shows hidden credential exfiltration, remote code loading, or automatic persistence. ## Affected versions and remediation This report applies to mcp-scraper@0.72.1. - Review the evidence and your use of mcp-scraper@0.72.1 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.
