RISK

Why x402_config is rated Critical

This tool configures automatic payment behavior (x402 auto-pay), which controls how financial transactions are authorized and executed. Misconfiguration could lead to unauthorized or unintended payments being made automatically. Sibling tools (charge_tab, create_escrow, award_bounty) confirm this is a financial transaction server. Auto-pay configuration is a financial control with high blast radius if misused.

From the tool's definition Configure x402 auto-pay settings for this session — 'auto-pay' directly relates to automated financial payment configuration; server description explicitly states 'perform financial transactions such as direct payments'
