Parameters from the server's own tool schema.
Although the core function is a simple color format conversion (Read/Execute level), the tool explicitly commits financial obligations by triggering micropayments in USDC per request. Per the rules, Financial is the most severe applicable category. Severity is low because the payment amount is negligible ($0.0001 max) and the color parsing itself is harmless.
From the tool's definition Pay up to $0.0001 per request with x402 USDC on Base or choose the fixed-price Solana USDC option
