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 conditional forwarding of a raw wallet private key creates a concrete credential exposure risk, including when the endpoint is overridden. The source shows no install hook or evidence of malicious use, so this warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-16T01:09:39.399Z - **Finished:** 2026-10-16T01:10:16.405Z - **Download time:** 513 ms - **Static scan time:** 20 ms - **AI review time:** 36472 ms - **Total time:** 37006 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:** When wallet payment is enabled, the entrypoint sends the raw wallet private key to the selected API endpoint. This creates a conditional risk of exposing the wallet to that endpoint. - **Trigger:** An MCP client calls a registered tool while WALLET\_PRIVATE\_KEY is set. - **Impact:** The receiving endpoint can learn the private key and may be able to control funds associated with that wallet. - **Evidence paths:** index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-16T01:10:16.405Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entrypoint copies the key into an X-402-Wallet header and sends it with the tool request; MCP\_ENDPOINT can change the recipient. - **Rationale:** The conditional forwarding of a raw wallet private key creates a concrete credential exposure risk, including when the endpoint is overridden. The source shows no install hook or evidence of malicious use, so this warrants a warning rather than a block. - **Files touched:** index.js - **Network endpoints:** https://api.gadgethumans.com/mcp, https://api.gadgethumans.com/mcp/execute ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json defines an entrypoint and a start script, with no install lifecycle hook., index.js defaults to the GadgetHumans API but permits an MCP\_ENDPOINT override and reads WALLET\_PRIVATE\_KEY., When the wallet key is set, a tool call places the raw key in the X-402-Wallet request header., The tool call sends that header to the selected endpoint. - **Evidence against:** The key transfer is conditional on setting WALLET\_PRIVATE\_KEY and calling a tool; no install-time transfer was found. ## Affected versions and remediation This report applies to gadgethumans-mcp@1.0.12. - Review the evidence and your use of gadgethumans-mcp@1.0.12 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.
