Extract metadata from multiple images (max 50). Price: $${PRICING.basic.price}-${PRICING.premium.price} USDC via x402
AI agents use extract_batch_metadata to commit financial operations through MCP Image Metadata Server — usually the final step of a payment, billing, or trading workflow. A call moves real money.
While the core function is metadata extraction (Read), each call triggers a financial transaction in USDC via x402 payment protocol. Per the rules, Financial is more severe than Read and takes precedence. An AI agent misusing this tool could repeatedly incur monetary charges, making severity high given batch processing of up to 50 images could amplify costs.
From the tool's definition 'Price: $${PRICING.basic.price}-${PRICING.premium.price} USDC via x402' — the tool commits financial obligations through x402 payment protocol upon each invocation
