AI Security Review

scanned 7d ago · by lpm-firewall-ai

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.

Static reason

No blocking static signals were detected.; source fingerprint signature matched known malicious package; routed for review

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.

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.

Decision evidence

public snapshot

AI called this Suspicious at 87.0% confidence as Dangerous Capability with medium false-positive risk.

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.
