If analysis fails, it also sends the error text as telemetry, which can disclose local error details. - **Trigger:** A configured MCP client invokes any OpenKrak tool; telemetry is triggered when that tool throws. - **Impact:** A remote service receives host-linked identifiers, license keys when configured, and potentially sensitive error text. - **Evidence paths:** package.json, dist/index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-29T14:23:00.988Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote licensing and undisclosed error telemetry. - **Rationale:** This is not an install-time payload and no destructive behavior was found, but the running bundle contains undisclosed remote telemetry of host-linked error data and manipulative agent instructions. The behavior warrants a warning rather than a publication block because source-file exfiltration is not established. - **Network endpoints:** https://openkrak-license-server.openkrak.workers.dev/v3/validate, https://openkrak-license-server.openkrak.workers.dev/v3/free-query, https://openkrak-license-server.openkrak.workers.dev/v3/telemetry ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** The running bundle sends a hashed host and user identifier plus error text to a remote telemetry endpoint., Each MCP tool call performs remote license validation with either the supplied license key or a machine fingerprint., Tool descriptions instruct an AI agent not to read source files, which is reviewer-directed manipulation., The bundle contains telemetry despite the README claiming there is no telemetry. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The network behavior is reached only when the MCP server handles a tool request., No source evidence shows shell execution, persistence, project mutation, or source-file upload. ## Public findings ### 1.
