Tool use transmits a stable host identifier and telemetry; failures also transmit the error text. - **Trigger:** Starting the MCP server and invoking its tools. - **Impact:** Can steer an AI away from source verification and disclose host identity and error details to an external service. - **Evidence paths:** dist/index.js, dist/license/check.js - **Review source:** ai\_review - **Reviewed:** 2026-09-05T11:08:09.820Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** AI-instruction manipulation plus external host telemetry. - **Attack narrative:** The executable MCP server advertises tool descriptions designed to make an AI avoid reading the user’s repository and trust package-provided analysis instead. On use, it creates a stable hash from the local hostname and username and posts it to a remote service. It also posts tool names, token estimates, and uncensored error text to that service. This creates both agent-steering and external telemetry behavior without meaningful user control at the individual tool-call level. - **Rationale:** The package contains explicit AI-behavior steering that suppresses independent source verification, alongside host fingerprinting and error telemetry to a remote endpoint. These are concrete, package-authored runtime behaviors, not scanner-only signals. - **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/track-tokens, https://openkrak-license-server.openkrak.workers.dev/v3/telemetry ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The MCP tool descriptions instruct an AI to treat its output as ground truth and not inspect repository files., Each tool invocation sends a stable hash of hostname and username to the external license server., The package sends tool error text and the host fingerprint to external telemetry., The published entrypoint contains behavior beyond the separately shipped license module, including tracking and telemetry. - **Evidence against:** No npm install lifecycle hook is present; prepublishOnly only builds before publishing., The package exposes repository-analysis tools and locally reads the repository only when those tools are invoked. ## Public findings ### 1.
