Layer2 MCP

A model context protocol server for interacting with the Ethereum layer 2 network for development and use, which provides a standardized interface for AI models to interact with blockchain networks, deploy tokens, and manage transactions.

Overview

The MCP Layer2 server implements the Model Context Protocol specification, providing AI models with tools to:

1. Basic

• Deploy new ERC20 token contracts
• Transfer ETH to specific addresses
• Transfer ERC20 tokens to specific addresses
• Perform batch transfers to random addresses for testing and simulation

2. Advance

• L1 Settlement & Data Availability Verification
• Support cross-chain This implementation enables AI assistants to directly interact with blockchain networks through a standardized protocol, making it easier to integrate blockchain capabilities into AI workflows.

Example Usage

Here's an example of how an AI assistant might use these tools:

1. Deploy a new ERC20 token contract:

👤You: Deploy a new ERC20 token
🤖AI: I'll deploy a new ERC20 token contract for you.
[Tool call: deployToken]
Result: Token deployed successfully!
Contract Address: 0xe7f1725E7734CE288F8367e1Bb143E90bb3F0512
Transaction Hash: 0xd4ec9bf7ca67a581e78a8637974cd84c9c3524a75efe8851b808f0d58879ebd9

2. Transfer tokens to an address:

👤You: Transfer 100 erc20 tokens to the address 0x6ea5e8971eC8cf32d43AeB18a6999aFc3a3ec65d
🤖AI: I need to deploy an ERC20 token contract before I can transfer 100 ERC20 tokens to a specified address.
[Tool call: deployToken]
Result: Token deployed successfully!
Contract Address: 0xe7f1725E7734CE288F8367e1Bb143E90bb3F0512
Transaction Hash: 0xd4ec9bf7ca67a581e78a8637974cd84c9c3524a75efe8851b808f0d58879ebd9
🤖AI: Now I will use the ERC20 token contract I just deployed to transfer 100 tokens to the address 0x6ea5e8971eC8cf32d43AeB18a6999aFc3a3ec65d.
[Tool call: transferToken with tokenAddress=0xe7f1725E7734CE288F8367e1Bb143E90bb3F0512, 
targetAddress=0x6ea5e8971eC8cf32d43AeB18a6999aFc3a3ec65d]
🤖AI: ERC20 token transfer has been successfully completed!
Details:
Token contract address: 0xe7f1725E7734CE288F8367e1Bb143E90bb3F0512
Receiving address: 0x6ea5e8971eC8cf32d43AeB18a6999aFc3a3ec65d
Transfer transaction hash: 0x82b7bdc69ffebfc946ab5101cf853a06e64d5aceaf96ca4fe70622fcee89d83e
The token has been successfully transferred to the specified address. Do you need to perform other operations?

3. Transfer ETH to an address:

🤖AI: I'll transfer 10 ETH to the specified address.
[Tool call: transferETH with targetAddress=0x6ea5e8971eC8cf32d43AeB18a6999aFc3a3ec65d, amount=10]
Result: ETH transfer successful!
Transaction Hash: 0x9f46076f1c9b84d49c7314d8b8586e20c5c5b389ec56931e510408b3f6052bac

4. Perform batch transfers:

🤖AI: I'll execute 100 token transfers over 10 seconds.
[Tool call: batchTransfer with tokenAddress=0xe7f1725E7734CE288F8367e1Bb143E90bb3F0512, 
transactionCount=100, durationSeconds=10]
Result: Batch transfer initiated!
Processing 100 transactions over 10 seconds.

Installation

# Clone the repository
git clone 
cd layer2-mcp
# Install dependencies
npm install
# Build the project
npm run build

How to use

Configuration

Create a .env file in the root directory with the following variables:

PRIVATE_KEY=your_ethereum_private_key
ETH_L2_RPC=your_layer2_rpc_url

Using with Cursor

Add a command type mcp server in the cursor mcp setting panel and fill in the execution command, for example: node \\wsl.localhost\Ubuntu-22.04\root\xxxx\xxxx\layer2-dev\build\index.js

Using with Claude Desktop

1. Install Claude Desktop
2. Add a new MCP server with the following configuration:

"layer2-mcp": {
"command": "node",
"args": [
"/path-to-layer2-mcp/build/src/index.js"
"env": {
"PRIVATE_KEY": "<<your eth-wallet private key>>",
"ETH_L2_RPC": "<<The layer2 chain rpc you want to interact with>>"

3. The tools will now be available in your Claude conversations

Testing with MCP Inspector

1. Install the MCP Inspector:

npm install -g @modelcontextprotocol/inspector

2. Start the server:

npm start

3. In another terminal, run the inspector:

mcp-inspector

4. Open in your browser to interact with the tools
