JMAP MCP 服务端测评：连接通信世界的智能枢纽

# 1. 克隆 JMAP MCP 项目仓库
git clone https://github.com/jmap-mcp/server-jmap.git
cd server-jmap

# 2. 安装依赖
npm install

# 3. 配置环境变量
# 创建 .env 文件，添加以下配置：
# JMAP_API_URL=https://jmap-api.example.com
# JMAP_ACCOUNT_ID=your_account_id
# JMAP_API_TOKEN=your_api_token

# 4. 全局安装（可选）
npm install -g .

# 5. 验证安装
jmap-mcp --version

# 问题1：权限错误
# 解决方案：以管理员身份运行 PowerShell

# 问题2：Node.js 版本不兼容
# 解决方案：使用 nvm 管理 Node.js 版本
nvm install 20.0.0
nvm use 20.0.0

# 问题3：JMAP 认证失败
# 解决方案：检查 API token 权限范围，确保包含邮件、日历读写权限

# 使用 Homebrew 安装
brew tap jmap-mcp/tap
brew install jmap-mcp

# 或者使用 npm 直接安装
npm install -g @jmap-mcp/server

# Ubuntu/Debian
curl -fsSL https://packages.jmap-mcp.org/install.sh | sudo bash
sudo apt-get install jmap-mcp-server

# 或者使用通用 Node.js 方式
npm install -g @jmap-mcp/server --unsafe-perm=true

假设团队规模：10人
年度时间节省：(4小时/周 × 52周 × $50/小时 × 10人) = $104,000
错误减少收益：避免错失会议、重复安排等损失 ≈ $15,000/年
总年度收益：约 $119,000

年度总成本：$2,400 (服务) + $1,200 (API) + $15,000 (开发维护) = $18,600
年度净收益：$119,000 - $18,600 = $100,400
第一年 ROI：≈ 540%
