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. The flagged credential flow sends a user-submitted OneSource API key to the OneSource API for validation. Runtime analytics is enabled by default, but the package describes it as anonymous and optional and provides an explicit opt-out; the inspected events contain usage metadata rather than credential or tool-input values. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-11-01T04:37:26.059Z - **Finished:** 2026-11-01T04:38:43.247Z - **Download time:** 1283 ms - **Static scan time:** 843 ms - **AI review time:** 75060 ms - **Total time:** 77188 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 attack identified; the reviewed behavior matches a OneSource MCP server with disclosed, disableable usage analytics. - **Trigger:** Server startup and tool use trigger runtime analytics; API-key validation occurs after a user submits a key through the connect flow. - **Impact:** No unintended credential disclosure, account action, or other attack behavior was identified in the reviewed paths. - **Review source:** ai\_review - **Reviewed:** 2026-11-01T04:38:43.247Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The submitted key is checked against the OneSource API. Analytics sends operational usage metadata to OneSource’s dashboard and can be disabled with ONESOURCE\_ANALYTICS=false. - **Rationale:** The flagged credential flow sends a user-submitted OneSource API key to the OneSource API for validation. Runtime analytics is enabled by default, but the package describes it as anonymous and optional and provides an explicit opt-out; the inspected events contain usage metadata rather than credential or tool-input values. - **Files touched:** package.json, dist/connect-page.js, dist/analytics.js, dist/register-api-tools.js, dist/register-docs-tools.js, dist/cli.js - **Network endpoints:** https://api.onesource.io/api/chain/chain-id?network=ethereum, https://1s-analytics.vercel.app/api/events, https://registry.npmjs.org/@one-source/mcp/latest ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The prepare script runs TypeScript compilation; no install hook behavior that contacts a host is shown., The connect flow validates a submitted API key against the OneSource API, using ONESOURCE\_BASE\_URL when configured., Runtime analytics defaults to OneSource’s dashboard and can be disabled with ONESOURCE\_ANALYTICS=false., Tool analytics reports operational metadata such as tool names, parameter names, client name/version, and a hashed session ID; the inspected event construction does not include parameter values or tool output., The setup prompt describes analytics as optional, states that it is on by default, and tells users how to turn it off. - **Evidence against:** Dashboard analytics is enabled by default and includes client name/version and tool usage metadata., The package performs network requests during runtime for analytics and version checks. ## Affected versions and remediation This report applies to @one-source/mcp@5.13.0. - Review the evidence and your use of @one-source/mcp@5.13.0 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.
