The Brain Layer for AI Trading Agents — quant calls + cross-venue arb across perp venues via MCP.
Smart contract security screening for Base. Check any contract or token for risk before interacting with it: Solidity source verification, upgradeable proxies and admin or mint powers, holder concentration, dangerous selectors, and B20 issuer powers. It surfaces the usual rug pull and scam indicators. The free tool needs no wallet and no API key; the paid Flash Audit (3.49 USDC over x402) returns a report with an anchored SHA-256. Payment is the only gate.
Non-custodial Hyperliquid perpetual-futures trading for Claude, Cursor and any MCP client: live market data, orderbook, candles, account state and — once the user arms it — order execution with on-chain leverage on the user's own wallet. No withdraw tool, server-enforced caps.
Three independent sensors read pre-price Bitcoin flows every 30s and reject almost everything. When they converge, a call is emitted with evidence — and the public rejection funnel proves how often it stays silent. Auditable in one call. Free tier; Pro 50 USD/month or 0.01 USD/query via x402.
Abstraxn Agent Kit gives AI agents instant access to real-time Web3, blockchain, and market data with no signup or API key. Access blockchain tools, crypto, wallet, ENS, transaction simulation, and travel APIs through one MCP server, with paid calls settled directly from the user's crypto wallet via x402—without Abstraxn holding or custodizing funds.
Emercoin swap exposes a keyless MCP exchanger at https://swap.emercoin.com/mcp (Streamable HTTP) so an AI agent holding USDT can buy EMC programmatically — no API key, no account, no callback. Tools: get_swap_config, buy_emc, get_order_status, cancel_order. Call buy_emc with an amount and your EMC address, pay the exact returned figure to the deposit address, then poll by token until delivered. Part of the broader effort to use Emercoin as an identity + memory layer for AI agents.
Teardrop is the native economic layer for AI agents, providing a robust suite of tools for multi-chain portfolio tracking, DeFi yield analysis, and gas estimation. It enables autonomous agents to securely find Web3 data and manage micro-payments on-chain with zero human intervention.
