## Manual Setup
### 1. Azure App Registration
1. Go to [Azure Portal](https://portal.azure.com) → Microsoft Entra ID → App registrations
2. New registration → Name: `microsoft-mcp`
3. Supported account types: Personal + Work/School
4. Authentication → Allow public client flows: Yes
5. API permissions → Add these delegated permissions:
- Mail.ReadWrite
- Calendars.ReadWrite
- Files.ReadWrite
- Contacts.Read
- People.Read
- User.Read
6. Copy Application ID
### 2. Installation
```bash
git clone https://github.com/elyxlz/microsoft-mcp.git
cd microsoft-mcp
uv sync
```
### 3. Authentication
```bash
# Set your Azure app ID
export MICROSOFT_MCP_CLIENT_ID="your-app-id-here"
# Run authentication script
uv run authenticate.py
# Follow the prompts to authenticate your Microsoft accounts
```
### 4. Claude Desktop Configuration
Add to your Claude Desktop configuration:
**macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
**Windows**: `%APPDATA%\Claude\claude_desktop_config.json`
```json
{
"mcpServers": {
"microsoft": {
"command": "uvx",
"args": ["--from", "git+https://github.com/elyxlz/microsoft-mcp.git", "microsoft-mcp"],
"env": {
"MICROSOFT_MCP_CLIENT_ID": "your-app-id-here"
}
}
}
}
```
Or for local development:
```json
{
"mcpServers": {
"microsoft": {
"command": "uv",
"args": ["--directory", "/path/to/microsoft-mcp", "run", "microsoft-mcp"],
"env": {
"MICROSOFT_MCP_CLIENT_ID": "your-app-id-here"
}
}
}
}
```
## Multi-Account Support
All tools require an `account_id` parameter as the first argument:
```python
# List accounts to get IDs
accounts = list_accounts()
account_id = accounts[0]["account_id"]
# Use account for operations
send_email(account_id, "user@example.com", "Subject", "Body")
list_emails(account_id, limit=10, include_body=True)
create_event(account_id, "Meeting", "2024-01-15T10:00:00Z", "2024-01-15T11:00:00Z")
```
## Development
```bash
# Run tests
uv run pytest tests/ -v
# Type checking
uv run pyright
# Format code
uvx ruff format .
# Lint
uvx ruff check --fix --unsafe-fixes .
```
## Example: AI Assistant Scenarios
### Smart Email Management
```python
# Get account ID first
accounts = list_accounts()
account_id = accounts[0]["account_id"]
# List latest emails with full content
emails = list_emails(account_id, limit=10, include_body=True)
# Reply maintaining thread
reply_to_email(account_id, email_id, "Thanks for your message. I'll review and get back to you.")
# Forward with attachments
email = get_email(email_id, account_id)
attachments = [get_attachment(email_id, att["id"], account_id) for att in email["attachments"]]
send_email(account_id, "boss@company.com", f"FW: {email['subject']}", email["body"]["content"], attachments=attachments)
```
### Intelligent Scheduling
```python
# Get account ID first
accounts = list_accounts()
account_id = accounts[0]["account_id"]
# Check availability before scheduling
availability = check_availability(account_id, "2024-01-15T10:00:00Z", "2024-01-15T18:00:00Z", ["colleague@company.com"])
# Create meeting with details
create_event(
account_id,
"Project Review",
"2024-01-15T14:00:00Z",
"2024-01-15T15:00:00Z",
location="Conference Room A",
body="Quarterly review of project progress",
attendees=["colleague@company.com", "manager@company.com"]
)
```
## Security Notes
- Tokens are cached locally in `~/.microsoft_mcp_token_cache.json`
- Use app-specific passwords if you have 2FA enabled
- Only request permissions your app actually needs
- Consider using a dedicated app registration for production
## Troubleshooting
- **Authentication fails**: Check your CLIENT_ID is correct
- **"Need admin approval"**: Use `MICROSOFT_MCP_TENANT_ID=consumers` for personal accounts
- **Missing permissions**: Ensure all required API permissions are granted in Azure
- **Token errors**: Delete `~/.microsoft_mcp_token_cache.json` and re-authenticate
