Evmole MCP Server

EVMole is a powerful library that extracts information from Ethereum Virtual Machine (EVM) bytecode, including function selectors, arguments, state mutability, persistent and transient storage layouts, and CBOR metadata, even for unverified contracts. It runs locally over stdio via the published package.

People connecting cloud infrastructure tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Rust.

01 · Install Evmole

Claude Code

claude mcp add cdump-evmole -- npx -y evmole-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "cdump-evmole": {
      "command": "npx",
      "args": [
        "-y",
        "evmole-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

npm package evmole-mcp - unscoped; check the name against the project README before installing

registry namespace io.github.cdump is GitHub-verified and matches the repo owner
