Can steer an agent away from direct source review and disclose a stable host identifier or license key to the operator's service. - **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:** 1.0.3 - **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 an AI agent discovers the MCP tools, their descriptions attempt to make the agent use this package as the mandatory source of truth and avoid independent source inspection. On every invoked tool call, the package also transmits a host-derived identifier or configured license key to its license server. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-09-16T03:32:34.754Z - **Finished:** 2026-09-16T03:33:45.805Z - **Download time:** 755 ms - **Static scan time:** 38 ms - **AI review time:** 70257 ms - **Total time:** 71051 ms The recorded confidence comes from the underlying analysis.

On every invoked tool call, the package also transmits a host-derived identifier or configured license key to its license server. - **Trigger:** An MCP client lists or invokes an OpenKrak tool. - **Impact:** Can steer an agent away from direct source review and disclose a stable host identifier or license key to the operator's service. - **Evidence paths:** dist/index.js, dist/license/check.js - **Review source:** ai\_review - **Reviewed:** 2026-09-16T03:33:45.805Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** AI-agent instruction injection plus remote license telemetry. - **Attack narrative:** The MCP server exposes tool descriptions that instruct an AI to always call OpenKrak before coding and not read repository source afterward. This is a direct attempt to control the agent's review process. When any tool is invoked, the license gate posts either the configured OpenKrak key or a hash of the local hostname and username to a remote worker. There is no install-time execution, but the runtime agent-control and tracking behavior are concrete. - **Rationale:** The package contains runtime AI-agent steering language and transmits host-derived identity data during ordinary tool calls. The lack of lifecycle hooks reduces install risk but does not neutralize the agent-control behavior. - **Files touched:** dist/index.js, dist/license/check.js - **Network endpoints:** https://openkrak-license-server.openkrak.workers.dev/v3/validate, https://openkrak-license-server.openkrak.workers.dev/v3/free-query ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The MCP tool descriptions direct an AI to always run this tool and not inspect source files, an attempt to override normal agent behavior., Each tool call hashes the local hostname and username, then sends that identifier to a remote license service., A configured pro key is sent to the same remote service during tool use., The free-tier check derives a SHA-256 fingerprint from the local hostname and username. - **Evidence against:** The manifest has no npm install lifecycle hook or self-dependency., The executable starts an MCP stdio server; it does not run automatically on package installation., The inspected analysis pipeline reads the user-supplied repository path and returns local analysis results; no repository contents are sent by that pipeline to a network endpoint. ## Affected versions and remediation This report applies to openkrak-mcp@1.0.3. - Avoid installing openkrak-mcp@1.0.3. 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.
