Give agents access to DeFi yield.
vaults.fyi gives agents 38 MCP tools for live yield data, vault comparison, transaction preparation, and position-aware workflows.
MCP and x402
Connect agents to live vault data, transaction tools, and position data. x402 support lets agents pay per request in USDC on Base without managing API keys.
