Brazilian foreign trade, crop and commodity data as a remote MCP server. Exports and imports from MDIC/ComexStat since 2000, by HS code (SH4/SH6/NCM) and partner country, in USD FOB and kilograms — plus crop production, supply-and-demand balances, climate readings and production forecasts for hubs such as soybean, coffee, corn, beef and cocoa. Every comparison is like-for-like: two windows of equal length, each labelled with the period it actually measures, and every answer names its window and its source. 14 read-only tools, metered in credits. Nothing to install: Streamable HTTP at https://mcp.kyrodata.com/mcp with a bearer key or OAuth 2.1 (PKCE). Official registry: com.kyrodata/kyrodata.
