qqconnect
This is a default read-only IMAP MCP server for QQ/163/126/Tencent Exmail mailboxes, with optional gated drafting and sending.
List linked mailboxes without exposing secrets and list IMAP folders.
Search one folder by sender, recipient, subject, date, or unseen status; returns envelope metadata only.
Read a single message as sanitized untrusted text using BODY.PEEK; OTP/security bodies are blocked.
List attachment metadata and download allowlisted attachments up to 2 MiB, rejecting executables, zip, and eml.
View and change settings for read/draft/send mode, send allowlist, and sensitive-body access.
Save new-message or reply drafts without sending.
Prepare and then send emails, replies, forwards, or drafts only after returning a preview and receiving a confirm_token.
Unbind a mailbox locally without deleting server-side mail.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@qqconnect 看看我 QQ 邮箱这周的未读"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
cn-mail-mcp
给任意 MCP 客户端用的 IMAP/SMTP 服务器,覆盖 QQ、163、126 和腾讯企业邮。默认只读。
授权码放在本机账号文件或 .env,不要写进 git,不要发给模型,不要出现在工具结果或日志里。
实验项目,不是各家官方邮箱连接器。Gmail / Outlook 请继续用官方连接器。安全问题走 Private vulnerability reporting,不要在公开 issue 里贴授权码。
快速开始
需要 Node.js 22+ 和 pnpm。
pnpm install
pnpm build获取 IMAP 授权码
第三方客户端不能使用网页登录密码,只要 IMAP 授权码。
QQ / Foxmail:https://mail.qq.com → 设置 → 账号与安全 → 安全设置 → 开启 IMAP/SMTP → 生成授权码。
163 / 126:网页邮箱 → 设置 → POP3/SMTP/IMAP → 开启 IMAP → 按提示生成客户端授权码。163 登录后必须发 IMAP
ID,本服务默认会发。腾讯企业邮:开启 IMAP/SMTP 后使用客户端专用密码。主机为
imap.exmail.qq.com:993/smtp.exmail.qq.com:465。
更细的步骤见 skills/mail-imap/SKILL.md。
最小配置
推荐先不把授权码写进客户端配置。把下面任一客户端配好并重启后,对助手说「绑定邮箱」。支持的客户端会:
用 form elicitation 收集邮箱地址、备注、服务商(不含授权码);
用 URL elicitation 打开只监听
127.0.0.1的一次性页面,让你在浏览器里填写授权码;把授权码写入本机
0600账号文件,登录 IMAP,只回报成功或失败。
账号文件默认在 $XDG_CONFIG_HOME/cn-mail-mcp/accounts.json,否则是 ~/.config/cn-mail-mcp/accounts.json(Windows 为 %APPDATA%\cn-mail-mcp\accounts.json)。查看路径:node dist/index.js accounts path。
若客户端没有对应的 elicitation 能力,助手会给出手动步骤。你也可以自己做:
cp .env.example .env
# 编辑 .env:MAIL_USER 与 MAIL_AUTH_CODE,等号两边不要空格
pnpm checkpnpm check 只在运行命令的这台机器上登录 IMAP,然后退出。成功说明这台机器和授权码可用。
终端交互绑定(授权码只在终端输入,不要贴进对话):
node dist/index.js accounts add
node dist/index.js accounts list
node dist/index.js --checkRelated MCP server: Universal Email MCP Server
客户端配置
把 /ABS/PATH/cn-mail-mcp 换成仓库绝对路径。配置里不要写授权码。
Cursor
文件:项目 .cursor/mcp.json,或全局 ~/.cursor/mcp.json。
stdio 字段以官方说明为准:type 必填,另有 command、args、env、envFile(Cursor MCP)。
{
"mcpServers": {
"cn-mail-mcp": {
"type": "stdio",
"command": "node",
"args": ["/ABS/PATH/cn-mail-mcp/dist/index.js"],
"envFile": "${workspaceFolder}/.env"
}
}
}envFile 只在你打算用 .env 时需要。只用本机账号文件时可以删掉这一行。
VS Code
文件:工作区 .vscode/mcp.json(用户级用命令面板 “MCP: Open User Configuration”)。顶层键是 servers,stdio 的 type 必填(VS Code MCP configuration)。
{
"servers": {
"cn-mail-mcp": {
"type": "stdio",
"command": "node",
"args": ["/ABS/PATH/cn-mail-mcp/dist/index.js"],
"envFile": "${workspaceFolder}/.env"
}
}
}Claude Desktop
官方快速开始使用 mcpServers + command + args,示例里没有 type(Connect to local MCP servers)。配置文件:
macOS:
~/Library/Application Support/Claude/claude_desktop_config.jsonWindows:
%APPDATA%\Claude\claude_desktop_config.json
改完后完全退出并重启 Claude Desktop。不要把授权码写进这个 JSON。
{
"mcpServers": {
"cn-mail-mcp": {
"command": "node",
"args": ["/ABS/PATH/cn-mail-mcp/dist/index.js"]
}
}
}通用 stdio
与 Claude Desktop 相同的 mcpServers 形状,适用于其他本地 stdio 客户端:
{
"mcpServers": {
"cn-mail-mcp": {
"command": "node",
"args": ["/ABS/PATH/cn-mail-mcp/dist/index.js"]
}
}
}stdout 只走 MCP JSON-RPC。日志在 stderr。
多账号
再绑第 2、第 3 个邮箱:再调用一次 add_mailbox,或在终端运行 accounts add。
手动 .env 时用后缀 _2、_3:
MAIL_USER=me@qq.com
MAIL_AUTH_CODE=
MAIL_USER_2=work@163.com
MAIL_AUTH_CODE_2=
MAIL_ACCOUNT_ID_2=worklist_accounts 只返回 id、地址、服务商和来源,不含授权码。多个邮箱时,后续工具要带 account_id。
解绑:unbind_mailbox,或 node dist/index.js accounts unbind <account_id>。这只解除本机绑定,不删除服务器上的邮件。
JSON 多账号仍可用 CN_MAIL_MCP_ACCOUNTS,但必须用 authCodeEnv 指向环境变量,不能内联 authCode。
工具
工具 | 作用 |
| 绑定邮箱。禁止向用户索取授权码 |
| 列出已绑定邮箱,不含授权码 |
| 解除绑定,不删服务器邮件 |
| 登录检查,只回报成功或失败 |
| 列文件夹 / 按信封搜索 |
| 读一封。正文在 |
| 附件元数据 / 按白名单下载(最大 2 MiB) |
| 草稿。需要档位 |
| 先返回预览和 |
| 查看或修改档位。打开 |
档位在 .cn-mail-mcp.json(示例见 .cn-mail-mcp.example.json),不要写进 .env。默认 read。打开发送:
node dist/index.js config set-mode send --allow you@qq.com或让助手调用 set_settings。mode=send 必须带非空白名单,并且先经过用户可见的确认。第一次 send_* 不发信,只给出预览;用户明确同意后,第二次调用才带 confirm_token 走 SMTP。
安全
默认只读。删除、移动、改旗标都没有实现。
正文是不可信数据。验证码 / 重置类邮件显示为
[redacted:otp],正文不会下载。读信使用
BODY.PEEK,文件夹以EXAMINE只读打开。发送默认关闭。需要档位
send、收件人白名单,以及预览确认。不接受去掉发信确认的改动。授权码、网页密码不要进入 git、模型上下文、工具结果或日志。
细节见 SECURITY.md。绑定流程如何对应 MCP 规范见 docs/onboarding.md。
故障排除
pnpm check认证失败:授权码不要带空格;网页里 IMAP 须开启;改过登录密码后要重新生成授权码。163
Unsafe Login:确认授权码是新的。不要改用 POP3。没有预设主机:地址不是 QQ / 163 / 126 / 企业邮时,在
.env里设置公网MAIL_HOST(993)和MAIL_SMTP_HOST(465)。内网和云元数据地址会被拒绝。工具列表对不上:看
get_settings的server.needs_restart。为真就停掉再启动 cn-mail-mcp。改了
.env仍提示没配置:文件要叫.env,等号两边不要空格。已经在环境里的同名变量不会被文件覆盖。list_accounts会重新读.env。
限制
客户端能不能在对话之外安全收下授权码,取决于它有没有声明 MCP elicitation 的 url 模式(form 按规范不能用来收集授权码)。托管或云端环境可能拦截 IMAP 993 和 SMTP 465;可选的本机回环 HTTP CONNECT 代理(CN_MAIL_MCP_MAIL_PROXY)只有在代理自己能到达这两个端口时才有用,它不会把 IMAP 改到 443。
开发
pnpm typecheck
pnpm test
pnpm knippnpm test 使用假邮箱后端,不登录真 IMAP。真登录用本地 pnpm check。

TDQS
Scored across 15 tools
Each tool targets a distinct email operation: settings, mailbox binding, draft creation, sending, searching, reading, and attachments. The four send variants and two draft savers are clearly differentiated by their descriptions and recipient/behavior rules.
All 15 tools follow a consistent snake_case verb_noun pattern, such as get_settings, save_draft, send_reply, and list_folders. The get_ versus list_ distinction is also semantically regular: singular resources use get_, collections use list_.
15 tools is at the upper bound of well-scoped, but each tool represents a meaningful email operation. The count is justified by the breadth of composing, sending, reading, searching, and attachment handling.
The set has a significant gap: both get_settings and list_accounts explicitly direct users to an add_mailbox tool that is not present, so mailbox onboarding cannot be completed. Additional message lifecycle operations like move/delete are absent as well, but the missing referenced tool is the critical failure.
