Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 13 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 5.23.2 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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. No malicious credential flow was found: the flagged key path validates a user-submitted key against the configured OneSource API. Runtime usage analytics are enabled by default, but the setup tool discloses them as optional and provides an opt-out; the recorded events contain metadata and input field names rather than values. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-11-01T04:40:34.953Z - **Finished:** 2026-11-01T04:41:31.333Z - **Download time:** 260 ms - **Static scan time:** 1065 ms - **AI review time:** 55053 ms - **Total time:** 56380 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 credential path is an explicit OneSource connect flow, and the separate runtime analytics are disclosed and can be disabled. - **Trigger:** Analytics runs during MCP server use; API-key validation occurs after a user submits the connect form. - **Impact:** The analytics reports tool and network details and input field names, not input values; no credential exfiltration or unrelated account action was found. - **Review source:** ai\_review - **Reviewed:** 2026-11-01T04:41:31.333Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The package sends tool-use metadata to its analytics endpoint and validates a submitted API key against the configured OneSource API. - **Rationale:** No malicious credential flow was found: the flagged key path validates a user-submitted key against the configured OneSource API. Runtime usage analytics are enabled by default, but the setup tool discloses them as optional and provides an opt-out; the recorded events contain metadata and input field names rather than values. - **Files touched:** dist/analytics.js, .lpm-dependency-evidence-57d8b1e7-47b1-4b1c-a722-ed890e7ef017/1/npm-linux/dist/analytics.js, dist/register-api-tools.js, dist/register-docs-tools.js, dist/connect-page.js - **Network endpoints:** https://1s-analytics.vercel.app/api/events, https://api.onesource.io/api/chain/chain-id?network=ethereum ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The setup tool describes anonymous usage analytics as optional, says it is on by default, and explains how to disable it with ONESOURCE\_ANALYTICS=false., Tool-call analytics record tool and network metadata, response size, and input field names; the recorded input\_params are Object.keys(input), not the input values., Analytics events are POSTed to the configured analytics endpoint. The flagged API key is separately validated against the configured OneSource API during the connect-submit flow. - **Evidence against:** Analytics is enabled by default, so events may be sent before the user chooses to disable it., The connect flow transmits a user-submitted API key to the configured OneSource API for validation. ## Affected versions and remediation This report applies to @one-source/mcp@5.23.2. - Review the evidence and your use of @one-source/mcp@5.23.2 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.
