已验证Streamable HTTP可网页运行知识与记忆开发者工具

概览

AI 生成的概览

一个远程 MCP 服务器，让 AI 编程助手实时获取 MetaMask Embedded Wallets（Web3Auth）文档、示例、SDK 源码和社区论坛内容。

可以做什么
搜索文档与示例项目，返回带摘要的页面链接和匹配示例。按 URL 获取文档页面的完整内容。从 GitHub 拉取 Web3Auth 集成示例的完整源代码。查询开源仓库中的 SDK 源码，如类型、接口和 hooks。搜索或获取 MetaMask Embedded Wallets 社区论坛的帖子。
适用场景
在开发或排查 MetaMask Embedded Wallets（Web3Auth）集成时适用，让助手基于最新文档、真实示例代码和 SDK 类型工作，而不是依赖静态文本。README 建议配合配套 skill 使用，以获得架构和密钥派生方面的指导。
运行要求
远程 HTTP 端点 mcp.web3auth.io，无需本地运行时；仅支持 stdio 的客户端可通过 npx 运行 mcp-remote 桥接。需要能访问该端点。托管部署需要 GITHUB_TOKEN，因为示例和 SDK 查询会大量调用 GitHub API，未认证的速率限制很低；可选的 DISCOURSE_API_KEY 和 DISCOURSE_API_USERNAME 用于认证论坛搜索。
安装前请注意
托管部署要求提供 GITHUB_TOKEN（个人访问令牌），应尽量缩小其权限范围。可选的 DISCOURSE_API_KEY 和 DISCOURSE_API_USERNAME 同样是凭据。工具本身只做读取查询，但查询内容和获取的 URL 会发送到第三方服务器，再由其调用 Algolia、GitHub 和 MetaMask 构建者论坛。README 提醒配置错误可能在生产环境改变钱包地址，应用生成的代码前应先审阅方案。

安装

在 SourceWeft 中

  1. 打开 控制台中的 MetaMask Embedded Wallets (Web3Auth) MCP，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

交给智能体安装

把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。

阅读 https://sourceweft.com/mcp/io.github.Web3Auth%2Fmcp-server/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。

README

MetaMask Embedded Wallets MCP Server

Build MetaMask Embedded Wallets integrations faster by giving your AI coding assistant live access to the documentation and deep knowledge of the SDK.

There are two things to set up:

  1. Skill — Teaches your AI assistant how to think about the SDK: architecture, framework quirks, key derivation rules, and common mistakes. No code in the skill; the MCP provides that.
  2. MCP server — Gives your AI assistant real-time access to search docs, fetch examples, and look up SDK types.

MCP Tools

ToolWhat it does
search_docsSearch documentation and example projects
get_docFetch the full content of any doc page
get_exampleFetch complete source code of an integration example
get_sdk_referenceFetch SDK types and hooks from the open-source repos
search_communitySearch the MetaMask Builder Hub for real user issues

Skill

The skill teaches your AI assistant the mental model for MetaMask Embedded Wallets. It includes SDK selection logic, key derivation rules, authentication concepts, platform quirks, and common mistakes that aren't obvious from the docs alone.

Tip: For the best experience, use the MCP server alongside the skill so that your LLM can fetch live docs and examples rather than relying on static text.

Universal install (works with 40+ agents)

bash
npx skills add web3auth/skill

The skills CLI by Vercel detects your active AI agent and installs to the right directory automatically — Cursor, Claude Code, Copilot, Kiro, Cline, Codex, Antigravity, and 40+ more.

To install for target a specific agent:

bash
npx skills add web3auth/skill -a cursor     # Cursor onlynpx skills add web3auth/skill -a claude-code # Claude Code only

MCP Server Setup

Cursor

Or use Warp's one-click MCP install if available in your version.

Cline (VS Code)

Add to your Cline MCP settings (Ctrl+Shift+P → "Cline: Open MCP Settings"):

json
{  "mcpServers": {    "web3auth": {      "url": "https://mcp.web3auth.io",      "transport": "http"    }  }}

Continue.dev

Add to your Continue config.json (open with Ctrl+Shift+P → "Continue: Open config.json"):

  • macOS/Linux: ~/.config/antigravity/mcp.json
  • Windows: %APPDATA%\antigravity\mcp.json

Add the server to the mcpServers section:

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

Antigravity hot-reloads MCP config changes — no restart required.

Xcode (via GitHub Copilot)

Xcode 26.3+ supports MCP via GitHub Copilot. Add the server to your Copilot MCP config or use the VS Code extension setup above (Copilot MCP registry is shared).

Alternatively, configure Xcode's agentic tools to point at https://mcp.web3auth.io directly via Settings → Copilot → MCP Servers.

Eclipse (via GitHub Copilot)

Eclipse with GitHub Copilot supports MCP. Add via Eclipse → Preferences → GitHub Copilot → MCP Servers → Add Server:

  • Name: web3auth
  • URL: https://mcp.web3auth.io

Neovim (avante.nvim)

In your Lua config, add via mcphub.nvim:

lua
require("mcphub").setup({  servers = {    web3auth = {      url = "https://mcp.web3auth.io",      transport = "streamable-http",    },  },})

Or using mcp-remote for compatibility:

lua
require("avante").setup({  mcp = {    servers = {      web3auth = {        command = "npx",        args = { "-y", "mcp-remote", "https://mcp.web3auth.io" },      },    },  },})

Neovim (codecompanion.nvim)

lua
require("codecompanion").setup({  extensions = {    mcp = {      servers = {        web3auth = {          command = "npx",          args = { "-y", "mcp-remote", "https://mcp.web3auth.io" },        },      },    },  },})

Amp (Sourcegraph)

Add to your Amp MCP configuration:

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

Goose

Add to ~/.config/goose/config.yaml:

yaml
extensions:  - name: web3auth    type: http    url: https://mcp.web3auth.io

5ire

In 5ire Settings → MCP Servers → Add:

  • Name: web3auth
  • URL: https://mcp.web3auth.io

Aider

Aider supports MCP via the LiteLLM bridge. Add to your Aider config:

yaml
mcp_servers:  web3auth:    command: npx    args: ["-y", "mcp-remote", "https://mcp.web3auth.io"]

Codex CLI

For Codex CLI or any stdio-only agent, use mcp-remote to bridge the HTTP endpoint:

bash
npm install -g mcp-remote

Then add to ~/.codex/config.toml:

toml
[mcp_servers.web3auth]command = "npx"args = ["-y", "mcp-remote", "https://mcp.web3auth.io"]

Or add to your agent's JSON config:

json
{  "mcpServers": {    "web3auth": {      "command": "npx",      "args": ["-y", "mcp-remote", "https://mcp.web3auth.io"]    }  }}

Static docs (llms.txt)

If your AI tool doesn't support MCP yet, use the static documentation file instead:

https://docs.metamask.io/llms-full.txt

For tools that support the llms.txt spec and can index docs automatically:

https://docs.metamask.io/llms.txt

Warning: The static file is a snapshot and may not include the latest updates. Use the MCP server when possible for always-current docs.

Start building

Once the skill and MCP are set up, ask your AI assistant directly. Good starting prompts:

  • "Add MetaMask Embedded Wallets to my React app with Google login."
  • "Set up social login wallets in my Next.js app using Wagmi."
  • "Integrate embedded wallets in my Flutter app."
  • "Why are my users getting different wallet addresses after I changed the login method?"

Tip: Use planning mode (where available) for your initial prompt. Review the plan before generating code — this catches architecture mistakes early and avoids config errors that would change wallet addresses in production.
