@mameta/japan-data-mcpPublisher documentation and package manifest were reviewed. EVM_PRIVATE_KEY is a wallet signing secret with spending authority, which does not fit the native authentication taxonomy; use a dedicated limited-funds wallet. The package, wallet flow, and APIs were not executed or independently security-audited.
