Security Report
This submission is not a legitimate MCP server but rather a TypeScript compiler library bundled with minimal configuration files. The code provided (node_modules/typescript/lib/typescript.js) is a massive compiled bundle of the TypeScript compiler itself, not an Etherscan MCP server. The package.json claims to be an Etherscan MCP but contains no actual server implementation. This appears to be either a placeholder, a misconfiguration, or a potential supply chain attack vector where the actual server code is missing or replaced.

"mcpServers": {
"etherscan": {
"url": "https://gateway.pipeworx.io/etherscan/mcp"
}
}
}
Or connect to the full Pipeworx gateway for access to all 1394+ data sources:
