## What it does

This server lets development agents interact with Sperax contracts on Arbitrum, BNB Chain, and Ethereum. It exposes tooling to monitor the USDs yield-bearing stablecoin, simulate mint operations, inspect vault collateral distributions, and verify peg stability against the dollar.

Built-in functions cover Chainlink oracle price feeds, veSPA lock evaluations, xSPA vesting positions, and Demeter farm listings. Communication runs via stdio or an HTTP service on port 3000.

Running the package requires Node.js 18+. To avoid rate limits on default RPC endpoints, pass your own node address in `ARBITRUM_RPC_URL`.
