## What it does

Solidity Compiler IDE is part of Lyra Web3 Playground, a browser-based environment for smart contract development. Write or paste a contract, select “Compile,” then “Deploy” to run it in a JavaScript VM. A wallet is not needed for that step. The compiler supports Solidity versions from 0.6.x through 0.8.24.

For local use, run `npm install && npm run dev` and open the IDE in a browser. The hosted demo is offline, so local startup is the available route described here. The project description does not provide commands for connecting this MCP server to Claude Code.

## Install

### Claude Code (native platform)

**Install**
- The MCP registry has no launch command for it: see the repository README

## When to use it
- write and compile a Solidity smart contract
- run a contract in a JavaScript VM without a wallet
- test a contract in a browser IDE
- work with Solidity versions from 0.6.x through 0.8.24

## Example prompts
- Open the Solidity environment and help me compile this smart contract.
- Show me how to run the contract in a JavaScript VM without a wallet.
- Help me start Lyra Web3 Playground locally with `npm install && npm run dev`.
