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. Source inspection found no install-time execution, covert exfiltration, persistence, or reviewer manipulation. Network and local-file capabilities are explicit, scoped, and aligned with the MCP service function. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-07T10:21:07.402Z - **Finished:** 2026-09-07T10:22:17.799Z - **Download time:** 780 ms - **Static scan time:** 9002 ms - **AI review time:** 60614 ms - **Total time:** 70397 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 confirmed malicious attack surface. The package is an MCP client for the named OKO service and performs networked webinar operations only after runtime use and authentication. - **Trigger:** Starting the MCP server and invoking an authenticated tool - **Impact:** It can act on the authenticated organizer's OKO resources, consistent with its stated MCP function. - **Review source:** ai\_review - **Reviewed:** 2026-09-07T10:22:17.799Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Scoped API-key authentication and user-confirmed webinar operations - **Rationale:** Source inspection found no install-time execution, covert exfiltration, persistence, or reviewer manipulation. Network and local-file capabilities are explicit, scoped, and aligned with the MCP service function. - **Network endpoints:** https://us-central1-okostreamcore.cloudfunctions.net/exchangeApiKey ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The runtime sends a configured OKO API key to its declared OKO authentication endpoint., It can read local image files only from explicit user-configured allowlisted directories., The manifest configures its prepublishOnly lifecycle script to run the build command. - **Evidence against:** The manifest has no install lifecycle hook; prepublishOnly is publish-time only., The entrypoint is an MCP server over standard input/output, not an install-time payload., Authentication, scoped permissions, and confirmation checks gate account-changing tools., The reported dynamic code generation is bundled validator-library code, not package-controlled payload execution. ## Affected versions and remediation This report applies to @okostream/mcp@0.12.12. - Review the evidence and your use of @okostream/mcp@0.12.12 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.
