MetaMask Embedded Wallets (Web3Auth) MCP
Wire MetaMask Embedded Wallets (Web3Auth) into your app with agent-guided SDK setup instead of reading docs alone.
Overview
io.github.Web3Auth/mcp-server is a MCP server for the Build phase that helps AI agents integrate MetaMask Embedded Wallets (Web3Auth) SDKs correctly.
What is this MCP server?
- Streamable HTTP remote at mcp.web3auth.io for Claude Code, Cursor, and other MCP clients
- Focused on MetaMask Embedded Wallets (Web3Auth) SDK integration patterns for coding agents
- Version 2.0.0 server schema aligned with MCP 2025-12-11
- Open-source reference repo at Web3Auth/web3auth-mcp on GitHub
- Reduces misconfiguration risk when agents scaffold login, session, and chain config
- Remote MCP URL: https://mcp.web3auth.io (streamable-http)
- Server version: 2.0.0
- Repository: github.com/Web3Auth/web3auth-mcp
Community signal: 3 GitHub stars.
What problem does it solve?
Agents often hallucinate wallet SDK setup and leave solo builders debugging opaque Web3Auth init and provider errors.
Who is it for?
Indie developers adding Web3Auth or MetaMask embedded wallets to a SaaS, mobile, or agent-backed app during active integration work.
Skip if: Teams that only need generic Ethers.js snippets with no Web3Auth dependency, or builders not using MCP-capable agents.
What do I get? / Deliverables
Your agent can follow Web3Auth-oriented integration guidance over MCP while you ship embedded wallet login in your app.
- Agent-guided Web3Auth SDK integration steps in your repo
- Correct remote MCP registration for mcp.web3auth.io
- Fewer broken wallet init paths during build

How it compares
MCP integration for Web3Auth SDKs, not a standalone agent skill or a replacement for the Web3Auth dashboard.
