Connects Claude to the Sperax DeFi ecosystem on Arbitrum and BNB Chain. You get 42 tools across five categories: USDs stablecoin operations (balance checks, mint simulations, rebase state), vault and collateral management (TVL, strategies, oracle prices), SPA governance and veSPA voting power calculations, Demeter yield farm queries with APR estimates, and Dripper yield distribution monitoring. The tools are read-only, pulling live data from on-chain contracts via RPC. Useful if you're building interfaces for Sperax products, analyzing yield opportunities across their farms, or need to query veSPA positions and voting power without writing contract calls yourself. Ships as an npm package with both stdio and HTTP server modes.
