ERC-7201 Namespaced Storage Layout MCP Server

A Model Context Protocol (MCP) server that allows AI agents to calculate and validate storage locations for ERC-7201 namespaced storage layouts.

Installation

Configure your MCP client to invoke npx -y @ericglau/erc7201-mcp using stdio.

Examples:

Cursor/Windsurf/Claude Desktop

{
  "mcpServers": {
    "erc7201": {
      "command": "npx",
      "args": [
        "-y",
        "@ericglau/erc7201-mcp"
      ]
    }
  }
}
