- 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
Set up the environment
Run locally using MCP Inspector
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):
2. Create a .env file in the project root
3. Add the following to the .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:
In Claude Desktop, you can find the json file by looking in Settings/Developer/Edit Config.
NOTE: You may need to replace "uv" with an absolute reference in "command"
Restart Claude Desktop each time you make a change to config or to the server code.
