wtf is fry-x402-mcp?

fry-x402-mcp connects AI assistants like Claude Desktop or Claude Code to a set of pay-per-call blockchain services run by fry.farm on the Algorand network. It works through MCP, a protocol that lets AI tools call outside services as if they were built-in functions, so once configured an AI agent can check on-chain data or build transactions just by using these tools in conversation. There are fifteen available actions in total, split between three free or very cheap data lookups, such as staking pool statistics and reward information, and twelve paid actions that build blockchain transactions like staking tokens, joining liquidity pools, minting an NFT, or setting up peer-to-peer trades. Each paid call costs a small fraction of a dollar, paid in a stable digital currency called USDC, and no account or API key is needed since the payment itself acts as the authorization. Importantly, this tool never holds anyone's private keys. When it builds a transaction, it hands back an unsigned version, and the AI agent's own wallet, set up separately by the person running it, signs the transaction locally before it gets submitted. The list of available tools is pulled live from fry.farm's own catalog when the server starts, so new services appear automatically without needing an update to this project. Setup involves cloning the repository, installing dependencies, and configuring an AI assistant to run it, along with providing the agent's own wallet phrase as an environment variable and a maximum spending limit per payment as a safety cap. The project is written in JavaScript, requires Node.js, and is released under the MIT license by the Fry Foundation. It is intended for people comfortable managing a cryptocurrency wallet and understanding the risk of giving an AI agent the ability to sign and submit blockchain transactions on its own.
