Analyze image for manipulation. Price: $${PRICING.standard.price}-${PRICING.forensic.price} USDC via x402
AI agents use detect_image_manipulation to commit financial operations through MCP Image Metadata Server — usually the final step of a payment, billing, or trading workflow. A call moves real money.
Although the core operation is analytical (image manipulation detection, which would normally be Read/Execute), the tool explicitly commits a financial obligation in USDC via x402 on every call. Per the rules, Financial is the most severe applicable category and takes precedence. Misuse by an AI agent could drain funds through repeated or unnecessary invocations.
From the tool's definition 'Price: $${PRICING.standard.price}-${PRICING.forensic.price} USDC via x402' — the tool triggers a financial transaction via the x402 payment protocol each time it is invoked.
