Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The MCP server loads encrypted code and obtains its key over the network before executing it. The payload cannot be statically audited. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-28T06:06:13.054Z - **Finished:** 2026-09-28T06:06:58.835Z - **Download time:** 772 ms - **Static scan time:** 400 ms - **AI review time:** 44608 ms - **Total time:** 45781 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The MCP server loads encrypted code and obtains its key over the network before executing it. The payload cannot be statically audited. - **Trigger:** A user invokes bead-pattern generation through the MCP server. - **Impact:** A service-controlled opaque algorithm executes in the consumer process; no specific harmful payload was confirmed statically. - **Evidence paths:** dist/mcp.js, dist/core.enc.json - **Review source:** ai\_review - **Reviewed:** 2026-09-28T06:06:58.835Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entry point fetches a key, decrypts core.enc.json, and dynamically executes the plaintext. - **Rationale:** The package uses a network-supplied key to unlock and execute code that is unavailable to static review. No lifecycle hook or confirmed malicious payload behavior was found. - **Files touched:** dist/core.enc.json - **Network endpoints:** https://pindoupic.com/api/v1/crypto/algo-key ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The MCP entry point retrieves a decryption key from the configured service endpoint., It decrypts the bundled opaque payload and executes the resulting text with a dynamic function., Pattern generation invokes the payload loader before processing input. - **Evidence against:** No install or postinstall lifecycle hook is declared., The inspected code does not show credential harvesting or a confirmed destructive action. ## Affected versions and remediation This report applies to @javascribe/pindoupic@0.5.0. - Review the evidence and your use of @javascribe/pindoupic@0.5.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
