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 source confirms conditional disclosure of a wallet private key to the package’s payment API, despite describing local signing. This warrants a warning for credential exposure, but the inspected source does not establish unrelated collection or further misuse. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-10-15T22:04:09.416Z - **Finished:** 2026-10-15T22:05:08.324Z - **Download time:** 769 ms - **Static scan time:** 25 ms - **AI review time:** 58114 ms - **Total time:** 58908 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:** Tool calls can disclose a configured wallet private key to the GadgetHumans API, creating conditional credential exposure. - **Trigger:** A tool call occurs while WALLET\_PRIVATE\_KEY is configured. - **Impact:** The API recipient receives the private key; source inspection does not establish its subsequent handling or use. - **Evidence paths:** index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-15T22:05:08.324Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The handler places the environment value in the X-402-Wallet request header and posts it to the API endpoint. - **Rationale:** The source confirms conditional disclosure of a wallet private key to the package’s payment API, despite describing local signing. This warrants a warning for credential exposure, but the inspected source does not establish unrelated collection or further misuse. - **Files touched:** index.js - **Network endpoints:** https://api.gadgethumans.com/mcp ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** index.js reads WALLET\_PRIVATE\_KEY from the environment and uses MCP\_ENDPOINT when set., Tool calls send the raw wallet key in the X-402-Wallet header when configured., Wallet-enabled calls POST to the API endpoint, which defaults to GadgetHumans’ API., The payment prompt says the agent signs micropayments, while the request code sends the key itself. - **Evidence against:** The default recipient is the package’s own documented API; source inspection does not establish how it handles the key. ## Affected versions and remediation This report applies to gadgethumans-mcp@1.0.11. - Review the evidence and your use of gadgethumans-mcp@1.0.11 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.
