It provides atomic Multicall3 reads, post-trade utilization and APY slippage checks, cap headroom decoding, and Pendle TWAP/logit-curve analysis through REST and MCP-compatible endpoints.

MCP server for Pi Network that enables AI agents to query Pi chain data (balances, transactions) and verify user tokens, with optional payment sending that is off by default.

Local Ethereum wallet for AI agents — read balances and history, request payments that a human approves by password in the app popup, and fetch x402-paywalled resources with USDC on Base. Keys are encrypted on-device and never leave your Mac.
