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.

Web scraping for agents. Point it at a URL and it returns the page as clean markdown, JavaScript-rendered pages included. Point it at a site and it maps the URLs or crawls the section you need in the background, a few pages at a time so results fit in the conversation. Search the web and read full pages, extract fields with a JSON schema you define (validated, never invented), read a store's catalogue or a blog's posts from the platform's own feed, and check whether a page has changed. Failed requests cost nothing. The free plan includes 1,500 credits a month.
