Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 12 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Matched warn-list - **Public report status:** Published - **Threat category:** Credential Exfiltration - **Selected version:** 0.15.0 - **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The unrestricted endpoint override can forward an existing credential to an arbitrary destination. This concrete conditional exposure warrants a warning, while the inspected package does not show an install-time or covert attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-26T06:52:31.044Z - **Finished:** 2026-09-26T06:53:35.136Z - **Download time:** 780 ms - **Static scan time:** 5726 ms - **AI review time:** 57586 ms - **Total time:** 64092 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:** A configured API key can be forwarded to an exchange URL selected through an environment variable. No install-time attack was identified. - **Trigger:** Starting the MCP server with an API key and invoking an authenticated operation. - **Impact:** A local operator or configuration source can expose the API key to an arbitrary endpoint. - **Evidence paths:** dist/server.js - **Review source:** ai\_review - **Reviewed:** 2026-09-26T06:53:35.136Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The server selects the exchange URL from environment configuration and posts the API key to it. - **Rationale:** The unrestricted endpoint override can forward an existing credential to an arbitrary destination. This concrete conditional exposure warrants a warning, while the inspected package does not show an install-time or covert attack. - **Network endpoints:** https://us-central1-okostreamcore.cloudfunctions.net/exchangeApiKey ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The executable entrypoint reads an API key and accepts an unrestricted exchange URL from an environment variable., When authentication is activated, it sends that API key in a POST body to the selected exchange URL., The package has no install lifecycle hook; its executable is invoked as an MCP stdio server. - **Evidence against:** The built-in exchange endpoint is an OKO-hosted service., Local image reads are disabled unless an explicit directory allowlist is configured. ## Affected versions and remediation This report applies to @okostream/mcp@0.15.0. - Review the evidence and your use of @okostream/mcp@0.15.0 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.
