Side-by-side comparison of two Model Context Protocol servers — install paths, tools, quality signals, and directory engagement so you can pick the right one for Claude, Cursor, and other MCP clients.
MCP server for Lighter — a zero-fee zk-rollup perpetual DEX. Trade 190 perpetuals (crypto + RWA: PAXG/XAU gold, XAG silver, WTI oil, equity tickers like TSLA/AMZN/ASML) from Claude Desktop, Cursor, Hermes, or any MCP client. Three credential tiers (PUBLIC market data → READ account → TRADE signing), native on-chain stop-loss / take-profit, server-side safety caps (max-quote-USD, slippage, symbol allowlist). pip install 0xdegenmo-lighter-mcp.
Non-custodial paying-fetch client for agents that pay APIs over HTTP 402 (x402, USDC on Base). The operator sets hard per-call/per-day/per-host spend caps, an approval threshold, and allow/deny lists, with an append-only receipt for every attempt; the agent can't raise its own limits. npx -y -p @forum-labs/payfetch payfetch-mcp
