200+ DeFi Protocol Tools

The most comprehensive DeFi tool coverage available via MCP. Integrations with Uniswap, Aave, Compound, Curve, Lido, Yearn, and 190+ other protocols — all callable as MCP tools from Claude or any MCP-compatible AI system.

⛓️

Multi-chain: EVM + Solana

Works across all major EVM chains (Ethereum, Base, Arbitrum, Optimism, Polygon) and Solana. The plugin architecture lets you selectively load tools for the chains and protocols your agent actually needs, keeping context window usage manageable.

🧩

Plugin Architecture

GOAT uses a plugin system where each DeFi protocol is a discrete plugin. Load only the plugins relevant to your use case — a yield optimizer doesn't need DEX tools; a trading agent doesn't need lending tools. Keeps the toolset focused and fast.

🔀

DEX Swaps / Lending / Staking / Bridging

Four major DeFi operation categories fully covered: token swaps across DEXes with routing, lending and borrowing on money markets, staking and liquid staking protocols, and cross-chain bridging between EVM and Solana networks.

// Claude Desktop config — load GOAT with specific plugins
{
  "mcpServers": {
    "goat": {
      "command": "npx",
      "args": ["-y", "@ainative/goat-mcp"],
      "env": {
        "WALLET_PRIVATE_KEY": "your-private-key",

// Example MCP tool calls Claude will have access to:
// uniswap__swap_exact_tokens_for_tokens
// aave__supply_token
// aave__borrow_token
// lido__stake_eth
// across__bridge_tokens

// Claude prompt example:
// "Swap 100 USDC for ETH on Base via Uniswap,
//  then stake 50% of the ETH with Lido"
