Smart Contract Analysis (Heimdall)

• Disassemble EVM bytecode into human-readable opcodes
• Decode raw calldata without requiring ABI
• Decompile EVM bytecode to Solidity source code and ABI
• Generate visual control flow graphs for EVM bytecode
• Detailed transaction inspection with calldata decoding and trace analysis

Usage

The server is designed to be used as an MCP tool provider for MCP Clients. When connected to a client, it enables the clients(claude desktop, cursor, client, etc.,) to perform Solidity and onchain operations directly.

Requirements

• Node.js v18+
• Foundry toolchain (Forge, Cast, Anvil)
• Heimdall-rs (for smart contract analysis)

Manual Setup

1. Ensure Foundry tools (Forge, Cast, Anvil) are installed on your system:

   curl -L https://foundry.paradigm.xyz | bash
   foundryup
   

2. Clone and build the server.

   bun i && bun build ./src/index.ts --outdir ./dist --target node
   
   

3. Update your client config (eg: Claude desktop):

 "mcpServers": {
    "foundry": {
      "command": "node",
      "args": [
        "path/to/foundry-mcp-server/dist/index.js"
      ],
      "env" :{
        "PRIVATE_KEY": "0x1234",
      }
    }
 }

[!NOTE] PRIVATE_KEY is optional

Setup using NPM Package

You can now install and run the server directly using npm:

Global Installation
