Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Scanner flags match a large user-invoked MCP web-intelligence product: no install hooks, first-party API traffic, and documented browser and CLI helpers. Dual-use session and agent-config features run only when the user starts those commands, not on npm install. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 82.0% - **Started:** 2026-09-17T12:54:39.958Z - **Finished:** 2026-09-17T12:59:43.862Z - **Download time:** 505 ms - **Static scan time:** 17240 ms - **AI review time:** 286158 ms - **Total time:** 303904 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:** No install-time or import-time attack is present. Dual-use browser, network, and Claude config helpers are the product and run only when a user starts a published command. - **Trigger:** User runs an MCP client, mcp-scraper-cli, or the hosted API; npm install does not execute package code. - **Impact:** No confirmed unconsented credential theft, persistence, or foreign agent hijack. - **Review source:** ai\_review - **Reviewed:** 2026-09-17T12:59:43.862Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User-invoked MCP web intelligence tools - **Rationale:** Scanner flags match a large user-invoked MCP web-intelligence product: no install hooks, first-party API traffic, and documented browser and CLI helpers. Dual-use session and agent-config features run only when the user starts those commands, not on npm install. ### Review decision - **Verdict:** Clean - **Confidence:** 82.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** The human CLI can spawn the Claude command to add or replace a user-scope MCP server when the user passes --apply., Hosted browser tools can reuse a saved ChatGPT or Claude login and store an account email on the connection record., Harvest debug code looks up the egress IP at api64.ipify.org., Replay code runs ffmpeg, and Maps navigation can wrap Google URLs through serp-redirector.vercel.app., The stdio MCP server sends the user-supplied API key to https://mcpscraper.dev., Published bins expose the MCP server, installer, and CLI. - **Evidence against:** package.json has no preinstall, install, or postinstall scripts; mcp-scraper-install only prints a banner., Agent config writes register this same package and require an explicit CLI command plus API key., Browser, Gmail, Nango, and OAuth paths match the documented web-intelligence product, not silent theft., Network targets are the product host or named vendors, not a hidden drop box., child\_process uses are ffmpeg, opening a checkout URL, and the Claude MCP helper., Library import only exports harvest and video helpers; it does not run those tools at load time. ## Affected versions and remediation This report applies to mcp-scraper@0.73.1. - Review the evidence and your use of mcp-scraper@0.73.1 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.
