0. 自用迁移笔记

git clone https://github.com/Cloud-li1/mcp-outlook-calendar.git
cd mcp-outlook-calendar
cp .env.example .env
# 编辑 .env，填入 OUTLOOK_CLIENT_ID（Azure 应用注册里拿）
pip install -e .
python3 src/server.py  # 首次运行完成 device code 认证，之后 token 自动缓存

Azure 应用注册 → 身份验证 → 允许公共客户端流 → 是 API 权限：Calendars.ReadWrite + Tasks.ReadWrite（委托） 如换机器，~/.cache/mcp-outlook-calendar/token_cache.bin 需重新认证

Prerequisites

1. Register an app at Azure Portal
   • Supported account types: "Accounts in any organizational directory and personal Microsoft accounts"
   • Redirect URI: https://login.microsoftonline.com/common/oauth2/nativeclient
   • API Permissions → Add Calendars.ReadWrite and Tasks.ReadWrite (both delegated)
2. Copy the Application (client) ID

Setup

cp .env.example .env
# Edit .env: paste your OUTLOOK_CLIENT_ID
pip install -e .

Usage

python3 src/server.py

On first run, the server prints a device code URL and code to stderr. Open the URL, enter the code, sign in with your Microsoft account. The token is cached at ~/.cache/mcp-outlook-calendar/token_cache.bin and auto-refreshes.

Migration to any MCP-compatible AI tool
