概览

AI 生成的概览

本地 MCP 服务器，让助手通过 macOS 邮件 App 在所有已配置账户中搜索、读取、发送和管理邮件。

可以做什么
  • 搜索与读取邮件：通过邮件 App 的信封索引按条件筛选邮件、读取正文、列出账户、邮箱、最近邮件和发件人。
  • 撰写与回复：从已配置账户发送新邮件，或按邮件 ID 回复已有邮件。
  • 整理邮件：设置已读与旗标状态、在邮箱间移动、移入废纸篓、批量标记已读或清空邮箱。
  • 邮箱与订阅管理：创建文件夹，并从邮件中提取退订链接。
适用场景
适合在已配置邮件 App 的 Mac 上使用，希望助手在不把邮件复制到别处的前提下，跨账户检索、整理、总结或起草并发送邮件。
运行要求
macOS 且已安装并配置邮件 App；Node.js 20+；支持 stdio 的 MCP 客户端（如 Claude Desktop）。宿主应用需授予完全磁盘访问权限和针对邮件的自动化权限，服务器进程会继承这些权限。
安装前请注意
可发送、回复、移动、删除邮件，甚至清空整个邮箱，存在误删或误发风险。它会读取本地邮件数据库并通过 AppleScript 操作邮件 App，邮件内容会作为工具结果传给 MCP 客户端。完全磁盘访问与自动化权限范围较大，建议限制宿主可调用的工具。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Mail.app，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。

Desktop only，通过 STDIO。 STDIO 服务会启动本地进程，因此需要 SourceWeft 桌面宿主。

其他 MCP 客户端

参照 仓库 中的启动说明。

README

mail-mcp

MCP server that gives Claude (and other MCP hosts) full access to Mail.app on macOS — search, read, send, reply, flag, move, and more — across every account configured in Mail.app (iCloud, Exchange, IMAP, etc.).

Prerequisites

  • macOS (Mail.app required)
  • Node.js 20+
  • An MCP host: Claude Desktop, Amazon Quick, or any stdio MCP client

Installation

Claude Desktop — one-click install (recommended)

  1. Download mail-mcp.mcpb from the latest release
  2. Double-click the .mcpb file — Claude Desktop installs it automatically
  3. Grant the required macOS permissions (see below)

Manual / Amazon Quick / other hosts

bash
npx @p-l-ta/mail-mcp

Or install globally:

bash
npm install -g @p-l-ta/mail-mcpmail-mcp

Point your MCP host at the mail-mcp binary (stdio transport). Example config:

json
{  "mcpServers": {    "mail-app": {      "command": "npx",      "args": ["@p-l-ta/mail-mcp"]    }  }}

Required macOS permissions

Grant these to the application that runs the MCP host (Claude Desktop, Amazon Quick, etc.):

PermissionWhere to grant
Full Disk AccessSystem Settings → Privacy & Security → Full Disk Access
Automation → MailSystem Settings → Privacy & Security → Automation

The MCP server process inherits permissions from the host application that launches it.

Tools

ToolDescription
search_emailsSearch messages via the Envelope Index database with rich filters
read_emailRead the full body of a message by its RFC message-id
list_accounts_and_mailboxesList all configured accounts and mailboxes with unread counts
list_recentList recent messages in a specific mailbox
list_sendersGrouped summary of senders with message and unread counts
send_emailSend a new email from one of the configured accounts
reply_to_emailReply to an existing message by RFC message-id
set_message_flagsSet read and/or flagged status on a message
move_emailMove a message to a different mailbox
trash_emailMove a message to Deleted Messages
create_mailboxCreate a new mailbox/folder in an account
bulk_mark_readMark all messages in a mailbox and/or from a sender as read
get_unsubscribe_linkExtract unsubscribe URLs from a message's headers and body
empty_mailboxDelete every message in a mailbox at once (Junk, Trash, etc.)

How it works

  • Search & read — queries Mail's own Envelope Index SQLite database directly for fast, structured results across all accounts
  • Actions (send, reply, flag, move, trash) — driven by AppleScript automation against Mail.app, so they work even for accounts where messages aren't stored as local files

Development

bash
npm installnpm run dev          # tsx watch — live reloadnpm test             # vitest unit testsnpm run build        # compile TypeScript → dist/npm run mcpb         # build Claude Desktop extension → build/mail-mcp.mcpb

Interactive MCP testing:

bash
npm run buildnpx @modelcontextprotocol/inspector node dist/server.js

Privacy Policy

mail-mcp is a local MCP server that runs entirely on your Mac. It has no backend, no telemetry, and makes no network requests of its own.

What it accesses:

  • Mail.app's Envelope Index database (~/Library/Mail/) — read-only, used for search queries
  • Mail.app via AppleScript — to read message bodies, send mail, flag, move, and trash messages

What it does NOT do:

  • Collect, store, or transmit any data outside your Mac
  • Connect to any external server or API
  • Log message content anywhere

All email data stays on your device and is only passed to the MCP host (Claude Desktop or another client) as part of normal tool responses. You control exactly which tools Claude can invoke.
