概览

AI 生成的概览

Nextmail 远程 MCP 服务器，让助手在 OAuth 授权的权限范围内发送邮件并处理你自己的 Nextmail 邮箱。

可以做什么
  • 通过 Nextmail SDK、API 或 CLI 让助手发送邮件
  • 通过 MCP 处理收件箱：读取邮件并进行修改，每个工具都标注为读取或更改
  • 在注册测试中用一次性收件箱接收验证邮件
  • 创建 Nextmail 账户，并用邮件收到的六位验证码完成验证
  • 提供从 Resend 迁移现有邮件发送配置的指引
适用场景
适合让助手从你自己的 Nextmail 工作区发信或整理收件箱，也适合测试流程需要接收验证邮件的场景。若你正从 Resend 迁移邮件发送，也可参考。
运行要求
远程端点 api.nextmail.sh/mcp，通过 HTTPS 访问，本地不运行任何程序。需要 Nextmail 账户，并在浏览器中通过 OAuth 登录，在授权页选择权限和可用地址。账户可由助手代为创建，用发送到你邮箱的六位验证码验证，同时获得供 CLI 和 API 使用的 API 密钥。
安装前请注意
助手可在你的工作区发送和更改邮件，请仔细核对 OAuth 授权页上批准的权限与地址，之后可在“已连接的应用”中收窄或移除连接。注册账户会把 API 密钥交给助手。邮件内容和账户数据会发送给 Nextmail 这一第三方服务。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Nextmail，将其添加到工作区。
  2. 连接 所需的 凭据。它们会被私密存储，绝不会在公开页面上展示。
  3. 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/sh.nextmail%2Fmcp/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。

其他 MCP 客户端

把它添加到你客户端的 mcpServers 配置中。 客户端会在首次连接时完成 OAuth 登录。

README

Nextmail for AI agents

Email for AI agents and for the people who build them, from Nextmail. This repository connects your agent to your own Nextmail mailbox, and teaches it the jobs people most often hand to an agent: sending email from code, working through an inbox, catching verification emails in tests, and moving from Resend.

What is in it

  • One MCP server, https://api.nextmail.sh/mcp, the remote server Nextmail runs. Your client signs in with OAuth in the browser, and on the consent page you choose which permissions and which addresses the agent may use. You can narrow or remove the connection later under Account, Connected apps.
  • Four skills, in skills/: sending email with the SDKs, the API or the CLI; working in a mailbox over MCP; disposable inboxes for sign-up tests; and moving from Resend.

Install

Claude Code

text
/plugin marketplace add nextmailhq/mcp/plugin install nextmail@nextmail

Claude, ChatGPT and other chat apps. Add https://api.nextmail.sh/mcp as a custom connector.

Codex. Add this to ~/.codex/config.toml:

toml
[mcp_servers.nextmail]url = "https://api.nextmail.sh/mcp"

Gemini CLI

bash
gemini extensions install https://github.com/nextmailhq/mcp

Any agent that reads skills

bash
npx skills add nextmailhq/mcp

Cursor, VS Code, Windsurf and other MCP clients. See https://nextmail.sh/docs/mcp/connect.md

Any other agent. Ask it to read this one Markdown page, which says how to connect over MCP, the command line or the API, and what to ask you before it sends anything: https://nextmail.sh/agent.md

No account yet

An agent can create the account for you, and your only part is the six-digit code emailed to you. It starts a sign-up with your address at POST https://api.nextmail.sh/signups, you give it the code, and POST https://api.nextmail.sh/signups/{id}/verify creates the account and gives the agent an API key for the command line and the API. Neither call needs a key, and npx @nextmail/cli signup --email <address> does both steps. To connect over MCP as well, set a password from the welcome email, then sign in as above.

What it runs, sends and fetches

Nothing in this repository runs on your machine. The skills are written instructions, and the plugin adds one remote MCP server, which your client reaches over HTTPS at https://api.nextmail.sh/mcp once you have signed in. Its tools act on your Nextmail workspace, with the permissions you approved, and every tool is marked as reading or as making changes, so your client can ask before anything is sent or changed. The skills link to the documentation at https://nextmail.sh, and to the Nextmail SDK and CLI packages, which are installed only if you choose to.
