Haiku MCP Server

An MCP (Model Context Protocol) server that enables AI agents to execute blockchain transactions via the Haiku API.

• Token Discovery: List supported tokens and DeFi assets across 21 blockchain networks
• Balance Checking: Get wallet balances across all supported chains
• Trading Quotes: Get quotes for swaps and portfolio rebalancing
• Transaction Building: Convert quotes to unsigned EVM transactions
• Wallet Integration: Extract EIP-712 payloads for external wallet signing (Coinbase, AgentKit, Safe, etc.)
• Self-Contained Execution: Optional end-to-end execution with WALLETPRIVATEKEY env var
• Yield Discovery: Find the highest-yielding DeFi opportunities across protocols and chains, filtered by APY, TVL, and category
• Portfolio Analysis: Analyze a wallet's holdings and surface context-specific yield opportunities based on what it actually holds

Installation

npm install haiku-mcp-server

Or run directly with npx:

npx haiku-mcp-server

Configuration

Environment Variables

Note: The API works without a key, but providing one unlocks higher rate limits for production use.

Claude Desktop Configuration

Add to your claudedesktopconfig.json:

{
  "mcpServers": {
    "haiku": {
      "command": "npx",
      "args": ["haiku-mcp-server"]
    }
  }
}

With API key for higher rate limits:

{
  "mcpServers": {
    "haiku": {
      "command": "npx",
      "args": ["haiku-mcp-server"],
      "env": {
        "HAIKU_API_KEY": "your-api-key-here"
      }
    }
  }
}

Available Tools

haikugettokens

Get supported tokens and DeFi assets for trading.

Parameters:

• network (optional): Filter by chain ID (e.g., 42161 for Arbitrum)
• category (optional): Filter by token category:
• token - Vanilla tokens (ETH, USDC, etc.)
• collateral - eg. Aave aTokens (deposited collateral)
• varDebt - eg. Aave variable debt tokens
• vault - eg. Yearn/Morpho yield vaults
• weightedLiquidity - eg. Balancer LP tokens
• concentratedLiquidity - eg. Uniswap V3 LP positions

Example:

{
  "network": 42161,
  "category": "token"
}

haikugetbalances

Get token balances for a wallet address across all chains.

Parameters:

• walletAddress (optional): Wallet address or ENS name. Required when WALLETPRIVATEKEY is not set; omit to auto-derive from WALLETPRIVATEKEY when it is set.

Example:

{
  "walletAddress": "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"
}

Omit walletAddress when WALLETPRIVATEKEY is set to use the derived address.

haikugetquote

Get a quote for a token swap or portfolio rebalance.

Note: Quotes are valid for 5 minutes, but execute as quickly as possible after quoting — the longer you wait, the more likely prices have moved and the transaction will fail on-chain.
