## 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:** 0.15.1
- **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 destination override creates a concrete conditional credential-exposure risk. The inspected manifest does not show an automatic install hook or a self-dependency chain.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 94.0%

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 unrestricted endpoint selected through an environment variable. No confirmed covert attack or install-time execution was identified.

- **Trigger:** Starting the MCP server and invoking authentication with an API key configured.

- **Impact:** A caller or environment controller could expose an OKO API key to a non-OKO endpoint.

- **Evidence paths:** dist/server.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-28T20:39:22.772Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The server uses the configurable exchange URL as the destination of a POST body containing the API key.

- **Rationale:** The unrestricted destination override creates a concrete conditional credential-exposure risk. The inspected manifest does not show an automatic install hook or a self-dependency chain.

- **Network endpoints:** https://us-central1-okostreamcore.cloudfunctions.net/exchangeApiKey

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 94.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** The active server reads the OKO API key and permits the exchange destination to be overridden through an environment variable., When authentication is triggered, the server posts that API key to the configured exchange destination., The manifest exposes the server as a command-line entrypoint and shows no install lifecycle hook in the inspected scripts.

- **Evidence against:** The default exchange destination is an OKO service endpoint., The request occurs only when an API key is configured and authentication is used.

## Affected versions and remediation

This report applies to @okostream/mcp@0.15.1.

- Review the evidence and your use of @okostream/mcp@0.15.1 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.
