Pre-trade token safety check for AI agents.

Ethereum, BSC, Base, Solana. Fail-closed - a check that cannot run answers unknown, never low. Publishes its own measured error rate with the benchmark harness in the repo. Free, no signup, no API key, MIT.

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.

Your Recipes, Beautifully Kept. weReci MCP server lets Claude and other MCP clients work with your personal weReci cookbook, the recipes you've imported from the web, social video and scanned family books. Interactive UI in the chat. weReci supports MCP Apps, so in clients that support it, tools return live views instead of plain text: recipe cards, shopping lists and your recipe graph. Clients without MCP Apps support get the same results as text. Find and read recipes: search your collection in plain language, open any recipe in full, or get an overview of what's in your cookbook. Cook with them: scale a recipe to any serving count, with cooking adjustments as well as amounts. Get substitution suggestions with ratios and caveats. Explore connections: browse your recipe graph (shared ingredients, techniques and cuisines), trace the connection between two recipes, and look up where a dish sits on the cuisine map. Themed collections: list the themed groups weReci curates from your cookbook, or ask it to reshuffle them. Shop: build a shopping list from one or more recipes, add or update items, and read the list back. Share: email a recipe to someone. Longer jobs like conceit reshuffles run in the background, with tools to check their progress. Everything is scoped to your own cookbook, or to a shared one you've joined.
