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 release is not malicious by the available source evidence, but its explicit user-command installer mutates an AI-agent configuration and registers an npx-launched server. No automatic lifecycle execution or concrete exfiltration behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-08-28T21:50:16.280Z - **Finished:** 2026-08-28T21:51:48.642Z - **Download time:** 252 ms - **Static scan time:** 29272 ms - **AI review time:** 62835 ms - **Total time:** 92362 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 explicit agent-install command can alter the user's Claude Code MCP registration. It is not triggered during npm installation. - **Trigger:** User runs mcp-scraper-cli agent install claude --apply with an API key. - **Impact:** Adds or replaces the mcp-scraper user-scope agent server, which can expand the agent's available capabilities. - **Evidence paths:** package.json, dist/bin/mcp-scraper-cli.js, dist/bin/mcp-scraper-install.js, dist/index.js, dist/server-EKRNKKLU.js - **Review source:** ai\_review - **Reviewed:** 2026-08-28T21:51:48.642Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User-requested Claude Code MCP registration through the local claude command. - **Rationale:** This release is not malicious by the available source evidence, but its explicit user-command installer mutates an AI-agent configuration and registers an npx-launched server. No automatic lifecycle execution or concrete exfiltration behavior was found. - **Files touched:** dist/bin/mcp-scraper-cli.js - **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 command can replace and add a user-scope Claude Code MCP entry., The configured server runs this package through npx and supplies its API key as environment configuration. - **Evidence against:** The manifest has no preinstall, install, or postinstall lifecycle hook., Agent configuration changes require the user to run the install command with --apply., No source-backed credential theft, covert exfiltration, or automatic persistence was found. ## Affected versions and remediation This report applies to mcp-scraper@0.77.0. - Review the evidence and your use of mcp-scraper@0.77.0 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.
