Mestre Prático • Brazil Retail & Commodities MCP

Calculates cross-state price differentials (percentage delta % and BRL spread) for inter-state freight routing and corporate procurement between an origin state and a destination state. When to use: Use ONLY when a user specifically needs a side-by-side comparative delta % or arbitrage spread between two different Brazilian states (e.g., SP vs RJ, MG vs PR). When NOT to use: Do NOT use to query prices of a single state (use brazil_fuel_prices, brazil_grocery_basket, or brazil_lpg_gas_prices). Read-only operation; no authentication required up to 60 req/min.

Issues a cryptographically signed Machine-to-Machine (A2A) Economic Intent Protocol and settlement guarantee. Enables enterprise autonomous agents (fleet management bots, hospital procurement systems, wholesale supply coordinators) to formalize an intention to acquire fuels, basic food baskets, or regulated pharmaceutical supplies. The oracle verifies factual minimum prices against primary audited databases and generates a tamper-proof SHA-256 digital certificate issued by Holding Arthur Luis Vieira dos Santos, valid for 24 hours as an immutable settlement ceiling. When to use: Use when two autonomous agents need to negotiate and seal a formal procurement protocol with verifiable digital signature and settlement bounds. When NOT to use: Do NOT use for simple read-only price checks (use brazil_fuel_prices, brazil_grocery_basket, or brazil_pharma_medicines). Idempotent cryptographic certificate generation.
