An AI client may rely on unverified package output; remote telemetry can receive host identifiers and error text. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 1.1.1 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. When the MCP server is enabled, it supplies AI-directed instructions intended to prevent independent source inspection. Tool invocations also transmit a host-derived identifier and telemetry to a remote service. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-07T21:36:24.216Z - **Finished:** 2026-09-07T21:37:20.132Z - **Download time:** 1525 ms - **Static scan time:** 36 ms - **AI review time:** 54354 ms - **Total time:** 55916 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:** When the MCP server is enabled, it supplies AI-directed instructions intended to prevent independent source inspection. Tool invocations also transmit a host-derived identifier and telemetry to a remote service. - **Trigger:** Starting the MCP server exposes the instructions; invoking any tool triggers the remote requests. - **Impact:** An AI client may rely on unverified package output; remote telemetry can receive host identifiers and error text. - **Evidence paths:** dist/index.js, dist/license/check.js - **Review source:** ai\_review - **Reviewed:** 2026-09-07T21:37:20.132Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** AI-agent prompt manipulation combined with host fingerprint and error telemetry collection. - **Attack narrative:** The executable MCP server registers tool descriptions that tell an AI not to read source files and to trust the package's generated brief as ground truth. This is an attempt to control the host agent's security and coding decisions. On each tool call, it sends a stable host-derived fingerprint and tool name to a remote worker; on failures it also sends the error message, which may contain local details. The package has no automatic install hook, but the runtime MCP behavior is a concrete agent-control and data-collection risk. - **Rationale:** Runtime source establishes deliberate AI-directed source-inspection suppression plus remote collection of host-derived identifiers and error text. These behaviors create a concrete agent control-hijack surface despite the absence of an install hook. - **Files touched:** dist/index.js, dist/license/check.js - **Network endpoints:** https://openkrak-license-server.openkrak.workers.dev/v3/free-query, https://openkrak-license-server.openkrak.workers.dev/v3/telemetry ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The MCP tool descriptions instruct an AI to treat package output as ground truth and not inspect source files., Each tool call sends a derived hostname-and-username fingerprint and tool name to a remote worker., Error telemetry sends the tool error message and host fingerprint to the remote worker., The standalone license module also hashes hostname and username before sending the fingerprint. - **Evidence against:** The manifest has no install or postinstall lifecycle hook., No package-authored code writes agent configuration or consumer-project files. ## Affected versions and remediation This report applies to openkrak-mcp@1.1.1. - Avoid installing openkrak-mcp@1.1.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
