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 post-login redirect deliberately reports the flow source and package version to the publisher’s site without a disclosed opt-out, so this is suspicious runtime telemetry. The inspected OAuth and Search Console requests send credentials and data to Google, and the redirect contains no Google token. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-11-03T15:15:19.776Z - **Finished:** 2026-11-03T15:16:07.574Z - **Download time:** 508 ms - **Static scan time:** 114 ms - **AI review time:** 47176 ms - **Total time:** 47798 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 login success flow sends the browser to the publisher’s site with package and flow identifiers, which is undisclosed runtime telemetry. - **Trigger:** A user runs the \`login\` command and completes Google OAuth. - **Impact:** The publisher’s site receives the login-flow source and package version, along with ordinary browser request metadata; no Google token was observed in that redirect. - **Evidence paths:** dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-11-03T15:16:07.574Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** After storing tokens locally, the local callback redirects the browser to \`www.getpercy.io\` with \`source=mcp-login\` and the package version. - **Rationale:** The post-login redirect deliberately reports the flow source and package version to the publisher’s site without a disclosed opt-out, so this is suspicious runtime telemetry. The inspected OAuth and Search Console requests send credentials and data to Google, and the redirect contains no Google token. - **Files touched:** ~/.search-console-mcp/credentials.json - **Network endpoints:** www.getpercy.io ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** After Google sign-in, the browser is redirected to the publisher’s site with \`source=mcp-login\` and the package version in the URL., The CLI handles login only when invoked with the \`login\` command; successful authentication triggers the redirect., The package sends no Google credentials to Percy in the inspected flow; token exchange and Search Console API requests target Google. - **Evidence against:** OAuth uses Google’s authorization and token endpoints, and requests Search Console data from Google., The package stores tokens locally in \`~/.search-console-mcp/credentials.json\`., The manifest’s \`prepublishOnly\` script builds the package; it is not an install hook. ## Affected versions and remediation This report applies to search-console-mcp-server@0.2.1. - Review the evidence and your use of search-console-mcp-server@0.2.1 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.
