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 API key is submitted through the OAuth connect flow and validated against OneSource’s API before an auth code is issued. Runtime analytics is enabled by default, but it reports usage metadata, logs its endpoint at startup, and can be disabled with ONESOURCE\_ANALYTICS=false; no credential theft or unrelated collection was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-11-02T15:49:49.799Z - **Finished:** 2026-11-02T15:51:02.843Z - **Download time:** 780 ms - **Static scan time:** 1017 ms - **AI review time:** 71246 ms - **Total time:** 73044 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 was identified. The flagged key flow validates a user-submitted OneSource key; default runtime analytics sends usage metadata and has a logged opt-out. - **Trigger:** The key is sent only when a user submits the OAuth connect form. Analytics events are generated when tools run and flushed periodically or after enough events accumulate. - **Impact:** No malicious impact identified from the reviewed source. Usage metadata leaves the runtime when analytics is enabled. - **Review source:** ai\_review - **Reviewed:** 2026-11-02T15:51:02.843Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The key is checked against the configured OneSource API. Analytics sends tool usage fields to the OneSource analytics service; ONESOURCE\_ANALYTICS=false disables collection. - **Rationale:** The flagged API key is submitted through the OAuth connect flow and validated against OneSource’s API before an auth code is issued. Runtime analytics is enabled by default, but it reports usage metadata, logs its endpoint at startup, and can be disabled with ONESOURCE\_ANALYTICS=false; no credential theft or unrelated collection was found. - **Network endpoints:** https://api.onesource.io/api/chain/chain-id (or ONESOURCE\_BASE\_URL override), https://1s-analytics.vercel.app/api/events, https://registry.npmjs.org/@one-source/mcp/latest ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The prepare script runs TypeScript compilation; the package entry points are the server factory and CLI., The connect-submit route accepts an API key as user input and validates it against OneSource’s API before issuing an auth code., The key validation request sends the candidate to the configured OneSource API base URL, defaulting to api.onesource.io., Runtime analytics reports tool names, input parameter names, timing, status, and response size rather than tool input values or responses., Analytics is sent to the OneSource analytics endpoint by default; startup logs its status and endpoint, and ONESOURCE\_ANALYTICS=false disables it., The payment wallet identifier included in analytics is a truncated SHA-256 hash. - **Evidence against:** No automatic credential discovery or transmission to an unrelated host was identified., The flagged API key flow requires a connect-submit request containing the user's key and returns an authorization code after validation., Analytics events contain usage metadata, not tool arguments or output; analytics can be disabled with an environment variable. ## Affected versions and remediation This report applies to @one-source/mcp@5.23.1. - Review the evidence and your use of @one-source/mcp@5.23.1 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.
