What io.github.sandeep-antier/abstraxn does
A free, public MCP (Model Context Protocol) server for Web3 data. Point any MCP client — Claude Desktop, Cursor, your own agent — at it and it can read live chain data (block height, gas, transaction status, ERC-20 info, spot prices) and, for a handful of pay-per-call tools, look up market data, wallets/tokens/ENS, and travel search.
