# # # 技术堆栈

• [[T0] (现代微软图形 SDK)
• [[T1]加上[T2]和TokenCachePersistenceOptions
• FastMCP——简单的符合MCP的服务器接口
• uv——快速Python依赖和env管理

□ □ □ 要求

该系统目前用于:

• 本地运行在macOS
• 与** Claude 桌面一起使用**
• 使用Azure注册的应用程序认证

您必须** admin 访问 Azure 租户** 才能配置此功能—— 应用程序注册需要微软图形范围( 如 [ [T6] , [ [T7]) 的同意, 这在大多数 Orgs 默认情况下是不可** 用户同意的。

□ 开始

OutlookMCPServer

This project is an MCP server that gives Claude Desktop access to your Microsoft 365 mail, calendar, and files using the Microsoft Graph API.

---

✨ Features

• ✅ Mail access: Compose, Respond, Sort, Search, Filter, and Analyze your inbox from Claude or any MCP-compatible agent
• ✅ Calendar support: Find invites, List Events, Compose/Update/Send Events
• ✅ OneDrive support: Search files, get file metadata
• ✅ Sharepoint support: Load drives, search files, get file metadata

---

🧱 Tech Stack

• msgraph (modern Microsoft Graph SDK)
• azure.identity with DeviceCodeCredential and TokenCachePersistenceOptions
• FastMCP — simple MCP-compliant server interface
• uv — fast Python dependency and env management

---

⚙️ Requirements

This is currently built to:

• Run locally on macOS
• Be used with Claude Desktop
• Authenticate using an Azure-registered application

⚠️ You must have admin access to an Azure tenant to configure this — the app registration requires consent for Microsoft Graph scopes (e.g. Mail.Read, Calendars.Read), which is not user-consentable by default in most orgs.

---

🚀 Getting Started

Clone the repository and navigate to it

git clone https://github.com/Norcim133/OutlookMCPServer.git
cd OutlookMCPServer

Set up the environment

uv venv
uv sync

Run locally using MCP Inspector

mcp dev main.py (expect errors)

It is much easier to get things working in the Inspector before trying to debug in Claude.

---

🔐 Authentication Setup

Before running the application, you need to set up the following:

1. Create an auth_cache folder in the project root (see note):

mkdir -p auth_cache

2. Create a .env file in the project root

touch .env

3. Add the following to the .env:

echo "AZURE_CLIENT_ID=" > .env
echo "AZURE_TENANT_ID=" >> .env
echo "AZURE_GRAPH_SCOPES=User.Read Mail.Read Mail.Send Mail.ReadWrite" >> .env

NOTE: Additional .env values required for file services NOTE: On first run, the application will authenticate using the DeviceCodeCredential flow and will create auth_record.json in the auth_cache folder automatically if successful.

You must have admin access to an Azure tenant to register an application with these permissions.

Claude for Desktop Integration

To integrate with Claude Desktop, add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "outlook": {
      "command": "uv",
      "args": [
        "run",
        "--with",
        "azure-identity,mcp[cli],msgraph-core,msgraph-sdk",
        "mcp",
        "run",
        "/absolute/path/to/OutlookMCPServer"
      ]
    }
  }
}

In Claude Desktop, you can find the json file by looking in Settings/Developer/Edit Config.
