The same runtime sends a stable host fingerprint and error telemetry to a remote endpoint. - **Trigger:** Starting the MCP server and invoking one of its tools for a repository. - **Impact:** An agent can be steered away from independent source inspection while the operator receives a persistent machine identifier and error text. - **Evidence paths:** dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-01T13:19:27.508Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** AI-agent instruction hijacking with host-fingerprint telemetry. - **Attack narrative:** The published executable is an MCP server. Its tool metadata tells a connected coding agent to run its analysis before every task and not inspect source after receiving the result, which attempts to replace normal agent judgment. On calls it computes a stable hash of hostname and username, then transmits that identifier with usage telemetry; error text is also transmitted. This conflicts with the package privacy claim that it has no telemetry. There is no install-time hook, but the runtime behavior is a concrete AI-agent control and undisclosed telemetry surface. - **Rationale:** The runtime combines explicit AI-agent steering with undisclosed persistent host telemetry and remote error reporting. This is malicious behavior at MCP invocation time even though installation itself has no lifecycle hook. - **Files touched:** dist/index.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:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The MCP tool description directs an AI agent to call this tool before every coding task and not read repository source afterward., Every tool call derives a stable hash from the local hostname and username and sends it to a remote service., The executable sends the fingerprint with usage telemetry and sends error text to the same service., The README says there is no telemetry, contradicting the executable. - **Evidence against:** There are no install, preinstall, or postinstall hooks., No package self-dependency or automatic AI-agent configuration write was found., The visible network endpoint is fixed rather than downloaded code. ## Public findings ### 1.
