Found a contract on Etherscan? One command. Claude can now use it.

Terminal

pip install abi-to-mcp

# Uniswap — Claude can swap tokens
abi-to-mcp generate 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D -o ~/uniswap-server

# ETH 2.0 Beacon Deposit — Claude can explore staking
abi-to-mcp generate 0x00000000219ab540356cBB839Cbe05303d7705Fa -o ~/eth-staking-server

# Any verified contract works
abi-to-mcp generate <ANY_CONTRACT_ADDRESS>

That's it. Every function, every event, every query — now a Claude tool.

Quick Start

1. Generate a server

bash

abi-to-mcp generate 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D -o ~/uniswap-server
cd ~/uniswap-server && pip install -r requirements.txt

2. Connect to Claude Desktop

Add to your config (~/Library/Application Support/Claude/claude_desktop_config.json on Mac):

config.json

{
  "mcpServers": {
    "uniswap": {
      "command": "python",
      "args": ["/Users/YOU/uniswap-server/server.py"],
      "env": {
        "RPC_URL": "https://eth.llamarpc.com"
      }
    }
  }
}

3. Ask Claude anything

"What's the best route to swap 1 ETH for USDC?"
"Get the reserves for the ETH/DAI pool"
"Show me recent swaps on Uniswap"

Claude now speaks DeFi.

pip install abi-to-mcp

# Uniswap — Claude can swap tokens
abi-to-mcp generate 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D -o ~/uniswap-server

# ETH 2.0 Beacon Deposit — Claude can explore staking
abi-to-mcp generate 0x00000000219ab540356cBB839Cbe05303d7705Fa -o ~/eth-staking-server

# Any verified contract works
abi-to-mcp generate <ANY_CONTRACT_ADDRESS>

That's it. Every function, every event, every query — now a Claude tool.

Quick Start

1. Generate a server

bash

abi-to-mcp generate 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D -o ~/uniswap-server
cd ~/uniswap-server && pip install -r requirements.txt

2. Connect to Claude Desktop

Add to your config (~/Library/Application Support/Claude/claude_desktop_config.json on Mac):

config.json

{
  "mcpServers": {
    "uniswap": {
      "command": "python",
      "args": ["/Users/YOU/uniswap-server/server.py"],
      "env": {
        "RPC_URL": "https://eth.llamarpc.com"
      }
    }
  }
}

3. Ask Claude anything

"What's the best route to swap 1 ETH for USDC?"
"Get the reserves for the ETH/DAI pool"
"Show me recent swaps on Uniswap"

Claude now speaks DeFi.
