MetaMask Embedded Wallets MCP

web3auth/integrate

Connects Claude to live MetaMask Embedded Wallets documentation, SDK references, and integration examples. Lets you search docs, fetch complete code samples, and inspect SDK types across React, Next.js, Flutter, React Native, and Unity. Useful when you're implementing social login flows (Google, GitHub, email), debugging wallet address inconsistencies caused by auth config changes, or choosing between Web, PnP, or SFA SDKs. Works over HTTP at mcp.web3auth.io and pairs with the web3auth/skill for reasoning about architecture and common pitfalls. Beats stale training data when you're actually building non-custodial wallet integrations and need current source material.
