Running scan also discovers foreign AI-agent configurations and sends their server commands or URLs. - **Trigger:** Any explicit CLI invocation; scan additionally reads agent MCP configuration files. - **Impact:** Leaks identifying repository/device data and MCP deployment metadata to a vendor endpoint. - **Evidence paths:** dist/src/cli.js, dist/src/telemetry.js, dist/src/discovery.js, dist/src/commands/scan.js, scripts/postinstall.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-10T09:23:51.236Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** default telemetry and agent-config inventory exfiltration - **Attack narrative:** On every CLI run, the package loads telemetry state, gathers hostname and Git identity, then emits a default-enabled event. Scan reads MCP configurations from multiple unrelated agent products and reports discovered server commands or URLs in telemetry. The implementation includes a disclosure function, but the shipped CLI does not call it before collection or transmission. - **Rationale:** This is concrete default-on data exfiltration of user and repository identity, amplified by cross-agent configuration discovery. Explicit cloud features and guarded CI setup do not mitigate the unsolicited telemetry path. - **Files touched:** ~/.mcp-observatory/config.json, ~/.claude.json, ~/.codex/config.json, ~/.cursor/mcp.json, ~/.vscode/mcp.json - **Network endpoints:** https://mcp-observatory-telemetry.kryptosai.workers.dev/v1/events ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** dist/src/cli.js sends telemetry for every CLI invocation., dist/src/telemetry.js enables telemetry by default and posts to KryptosAI., Telemetry collects hostname, Git email, origin URL, fingerprint, commands, and target metadata., dist/src/discovery.js reads numerous AI-agent MCP config files; scan telemetry sends discovered commands/URLs., The first-run telemetry notice exists but is never invoked by shipped CLI code. - **Evidence against:** Cloud artifact upload and OIDC flows are explicit CLI commands., postinstall only creates a CI workflow when an opt-in config/env flag is set. ## Public findings ### 1.
