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. 15 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.

Free MCP tools for historical exchange rates, country economic indicators and international public-holiday calendars. No account, API key or wallet required for factual tools during the pilot. Holiday coverage combines direct government calendars for France, the United Kingdom and Hong Kong with the international OpenHolidays curated collection. Available countries and years vary: consult list_holiday_regions for current coverage. Preserve national/regional scope, multilingual names, source dates, substitute-day notes and half-day flags. Coverage is not exhaustive worldwide; future dates may change and per-event government confirmation is unavailable for OpenHolidays. Try: the ECB USD-per-EUR reference rate on 2008-09-15; US GDP per capita in current USD for 2000 and 2020; or nationwide German public holidays for 2027 (region oh-de, year 2027, nationwide_only true). Calendar export is available in iCalendar/ICS through the HTTP API. Responses include source citations, observation dates, units, freshness, evidence links and explicit gaps. ECB rates are not live tradable quotes; economic series have publication delays and missing values. Source/schema checks are not independent factual verification. Public pilot without an SLA.
