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 sends default runtime telemetry to its own analytics service, including client details and a wallet identifier, without clear user-facing disclosure. The flagged API-key validation is a separate user-submitted flow to the OneSource API and does not establish credential exfiltration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-11-01T04:39:30.477Z - **Finished:** 2026-11-01T04:40:19.110Z - **Download time:** 1272 ms - **Static scan time:** 811 ms - **AI review time:** 46549 ms - **Total time:** 48633 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:** Default runtime analytics sends tool-usage events to the OneSource analytics service; the telemetry is not disclosed in the inspected README. - **Trigger:** The MCP server creates analytics by default; tool calls generate events that flush when the buffer fills or on its periodic timer. - **Impact:** The service receives identifying usage metadata without clear user-facing disclosure, so this is suspicious runtime telemetry. - **Evidence paths:** dist/analytics.js, dist/register-api-tools.js, .lpm-dependency-evidence-4a7ab65f-51a3-419a-95a0-ab48e7abd443/1/npm-linux/dist/analytics.js - **Review source:** ai\_review - **Reviewed:** 2026-11-01T04:40:19.110Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The package posts buffered events to https://1s-analytics.vercel.app/api/events. Events include client details, a hashed session ID, and a wallet identifier. ONESOURCE\_ANALYTICS=false disables analytics. - **Rationale:** The package sends default runtime telemetry to its own analytics service, including client details and a wallet identifier, without clear user-facing disclosure. The flagged API-key validation is a separate user-submitted flow to the OneSource API and does not establish credential exfiltration. - **Files touched:** dist/analytics.js, dist/register-api-tools.js, dist/connect-page.js, .lpm-dependency-evidence-4a7ab65f-51a3-419a-95a0-ab48e7abd443/1/npm-linux/dist/analytics.js - **Network endpoints:** https://1s-analytics.vercel.app/api/events, https://api.onesource.io/api/chain/chain-id?network=ethereum ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The server configures dashboard analytics by default with the OneSource analytics endpoint and a built-in analytics key; an environment variable can disable it., API tool calls record usage events, including tool and network names, input parameter names, response size, and a hashed session ID., Events also include client name and version, transport, and a wallet identifier., The analytics implementation POSTs buffered events to its configured /api/events endpoint using a bearer key., The flagged API-key flow accepts a key in an OAuth connect submission and validates it against the configurable OneSource API base. - **Evidence against:** The analytics destination is the package’s own analytics service, and the source provides an opt-out variable., The inspected telemetry records parameter names rather than parameter values; the flagged API key is sent to the OneSource API service for validation. ## Affected versions and remediation This report applies to @one-source/mcp@5.14.0. - Review the evidence and your use of @one-source/mcp@5.14.0 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.
