Web3Auth Agent Skill

Agent skill for MetaMask Embedded Wallets (Web3Auth). Teaches your AI coding assistant the SDK's architecture, authentication concepts, key derivation rules, platform quirks, and common mistakes — things that aren't obvious from the docs alone.

Install

npx skills add web3auth/skill -y

Works with Cursor, Claude Code, Copilot, Kiro, Cline, Codex, Antigravity, Windsurf, and 40+ more agents.

To install globally (available in all projects) or target a specific agent:

npx skills add web3auth/skill -g -y            # global
npx skills add web3auth/skill -a cursor -y     # Cursor only
npx skills add web3auth/skill -a claude-code -y # Claude Code only

Pair with the MCP server

The skill teaches the mental model. The MCP server gives your AI real-time access to live docs, examples, and SDK source — use both together for best results.

Add to your MCP config:

{
  "mcpServers": {
    "web3auth": {
      "url": "https://mcp.web3auth.io"
    }
  }
}

See the full setup guide for one-click installs for every IDE (Cursor, VS Code, JetBrains, Claude, Windsurf, and more).
