Hl Vaults X402 is an MCP server that provides Hyperliquid vault summaries — APR, TVL, PnL, and followers — through a pay-per-call model using the x402 protocol (USDC on Base L2). It requires no API key, no signup, and has no rate-limit wall, making it ideal for AI agents that need on-demand vault performance data.
Add the server URL to your MCP client config (e.g., Claude Desktop, Cursor, ElizaOS): "url": "https://hl-vaults.api.klymax402.com/mcp". For HTTP, call GET /api/vaults; any x402-aware client automatically handles the 402 payment challenge. The default tool is hyperliquid_get_vault_data with an optional limit parameter.
hyperliquid_get_vault_data.x402 is an HTTP-native pay-per-call protocol. No signup or API key is needed; payment is made per request using USDC on Base L2.
Payments are on Base L2 (`eip155:8453`) using USDC, with Coinbase CDP as the primary facilitator and PayAI as fallback.
Each call to `hyperliquid_get_vault_data` costs $0.003 USDC.
The `hyperliquid_get_vault_data` tool accepts an optional `limit` (number) to cap the number of vaults returned (default: 20).
No. The server uses x402 for payment, eliminating the need for API keys or signup.
