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 default endpoint is package-aligned, but a custom CORTEX\_URL can direct ordinary authenticated requests to another host. This conditional credential exposure warrants a warning; the inspected source does not establish a hidden default recipient or an install-time attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-23T02:24:02.772Z - **Finished:** 2026-10-23T02:26:01.986Z - **Download time:** 1022 ms - **Static scan time:** 1999 ms - **AI review time:** 116193 ms - **Total time:** 119214 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 conditional token exposure exists when the MCP server uses a custom API URL. It sends the existing Cortex bearer token to that URL without restricting the destination to the official service. - **Trigger:** CORTEX\_URL is set to a custom host and the MCP server starts. - **Impact:** The custom host operator can receive the Cortex token and gain access associated with that account. - **Evidence paths:** lib/server.mjs, lib/diagnose.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-23T02:26:01.986Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The runtime resolves CORTEX\_URL as its API base and attaches the existing token as a bearer authorization header on API requests. - **Rationale:** The default endpoint is package-aligned, but a custom CORTEX\_URL can direct ordinary authenticated requests to another host. This conditional credential exposure warrants a warning; the inspected source does not establish a hidden default recipient or an install-time attack. - **Network endpoints:** https://agnoclast.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The normal MCP server reads a supplied Cortex token, resolves its API base from CORTEX\_URL, and runs from the package entry point., The default API host is agnoclast.com, but the resolver accepts custom URLs except for a limited class of protected Vercel hosts., Normal API requests attach the existing bearer token to the selected base, with no destination-specific check in the request caller., The manifest declares no install lifecycle hook; setup and cross-editor wiring are exposed as explicit CLI commands., The agent integration locations write editor configuration through setup or install paths; these findings do not establish a separate attack. - **Evidence against:** The default destination is the package-aligned Cortex host, and the credential exposure requires configuring a custom CORTEX\_URL. ## Affected versions and remediation This report applies to @theronap/cortex-mcp@0.9.256. - Review the evidence and your use of @theronap/cortex-mcp@0.9.256 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.
