MetaMask Embedded Wallets MCP (formerly Web3Auth) gives AI coding assistants live access to Embedded Wallets documentation, SDK references, integration examples, and community troubleshooting. MetaMask Embedded Wallets is not a wallet app itself, but embedded wallet infrastructure that helps developers add non-custodial Web3 wallets to web, mobile, and gaming apps using familiar login methods like Google, GitHub, email, SMS, and other OAuth or passwordless flows. This MCP server is built for real integration work. It lets agents search docs, fetch full documentation pages, retrieve complete example code, inspect SDK types and hooks, and surface real-world implementation issues. It is especially useful for tasks like choosing the right SDK, implementing social login, understanding key derivation behavior, avoiding wallet address changes caused by auth or configuration mistakes, and debugging framework-specific issues across React, Next.js, Flutter, React Native, and other platforms. Use it when you want an AI assistant to generate or review MetaMask Embedded Wallets integrations using current source material instead of stale model memory. Pair it with the MetaMask Embedded Wallets Skill for best results: the skill teaches the assistant how to reason about architecture, authentication, SDK selection, and common pitfalls, while this MCP server provides up-to-date docs, examples, SDK references, and implementation details.

API auth for AI agents. Replace shared API keys with signed, non-replayable requests. Agents discover, self-register, and sign requests with ERC-8128.

Bidirectional DLP scanning for every MCP tool call — secrets, PII, prompt injection, and malicious code caught in both directions. Route all your agents (Claude, ChatGPT, Gemini, Cursor) through one endpoint with unified audit logging. Memory Vault for persistent cross-agent context. Bug Vault with 8.6M+ coding patterns across 48 languages. Free tier with 1,000 requests/day. Team RBAC and tool-level DLP policies coming March 2026.

Turn AI conversations into live apps. Describe what you need, and AppDeploy deploys a real, full-stack app. From idea to live app in minutes, without touching infrastructure.
