Layer2 MCP Server is a Model Context Protocol server that lets AI models interact with Ethereum layer 2 networks. It provides a standardized interface for deploying ERC20 tokens, managing transactions, and testing cross-chain operations.
Clone the repository, install dependencies with npm install, and build with npm run build. Configure a .env file with PRIVATE_KEY and ETH_L2_RPC. Then add the server to a client like Claude Desktop or Cursor using the provided configuration. For testing, run npm start and use MCP Inspector.

Any Ethereum‑compatible network, including Ethereum Mainnet, layer 2 chains (Optimism, Arbitrum, etc.), and local development networks (Hardhat/Ganache).
Add a JSON entry with the `command` set to `node`, `args` pointing to the built script, and `env` containing `PRIVATE_KEY` and `ETH_L2_RPC`.
Yes. Use MCP Inspector by running `mcp-inspector` after starting the server with `npm start`, then open `http://localhost:5173`.
MCP Toolbox for Databases is an open source MCP server for databases.

A good sequence diagram can solve almost any communication problem in engineering. Volley lets your agent write them as plain text, with the real request and response payloads on every arrow. It checks its own syntax wi
