Manual Setup

1. Azure App Registration

1. Go to Azure Portal → 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
   • Mail.Send
   • Calendars.ReadWrite
   • Files.ReadWrite
   • Contacts.Read
   • People.Read
   • User.Read
6. Copy Application ID

2. Installation

git clone https://github.com/elyxlz/microsoft-mcp.git
cd microsoft-mcp
uv sync

3. Authentication

# 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

{
  "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:

{
  "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. You can pass:

• The exact home_account_id (recommended)
• The account username (email), e.g. admin@contoso.com
• The keyword default to use the first authenticated account

# 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")

# Or via username or 'default'
list_emails("admin@contoso.com", limit=10, include_body=True)
list_emails("default", limit=10, include_body=True)

Professional Email Templates

The KamDental Email Framework provides professional, branded email templates:

    account_id="default",

            "role": "General Dentist",
            "production": 125000,
            "goal_percentage": 1.04
        }
    ],
    period="January 2024",
    alerts=[
        {
            "type": "warning",
            "title": "Production Below Target",
            "message": "Current production is 5% below monthly target."
        }
    ]
)

Executive Summary Example

await send_executive_summary(
    account_id="default",
    to="executive@kamdental.com",
    locations_data=[
        {
            "name": "Baytown",
            "production": 285000,
            "target": 300000,

            "title": "Overall Performance",
            "description": "Combined production at 96% of target"
        }

Codex CLI Setup

You can run this MCP server from Codex CLI by adding an MCP server entry that launches the microsoft-mcp binary (or uvx command) with the required environment variable.

1. Add to your Codex config file (adjust path to wherever your Codex CLI reads config):

[mcp_servers.microsoft]
command = "uvx"
args = [
  "--from",
  "git+https://github.com/elyxlz/microsoft-mcp.git",
  "microsoft-mcp",
]
env = { "MICROSOFT_MCP_CLIENT_ID" = "your-azure-app-id", "MICROSOFT_MCP_TENANT_ID" = "common" }

Notes:

• MICROSOFT_MCP_CLIENT_ID is required (Azure App Registration → Application ID).
• Optional MICROSOFT_MCP_TENANT_ID can be common, your tenant GUID, or consumers for personal accounts.
• The above uses uvx to fetch/run directly from GitHub. If you’re developing locally, use the local variant below.

2. Local development variant (run from your checked-out repo):

[mcp_servers.microsoft]
command = "uv"
args = ["--directory", "/path/to/microsoft-mcp", "run", "microsoft-mcp"]
env = { "MICROSOFT_MCP_CLIENT_ID" = "your-azure-app-id", "MICROSOFT_MCP_TENANT_ID" = "common" }

3. Start Codex CLI and ensure the server appears in the tool list. If authentication is needed, use the auth_operations tool:

• auth_operations(action="authenticate") → visit the URL and enter the code
• auth_operations(action="status") → verify at least one account is authenticated
• Use account_id="default" or your email (e.g., admin@contoso.com) when calling tools

Troubleshooting:

• If email sending returns 403 on /me/sendMail, add the Mail.Send delegated permission to your Azure app and grant admin consent.
• If passing an account_id that doesn’t exist, the server now returns a clear error with the list of available accounts. You can also pass default to use the first account.

Example: AI Assistant Scenarios

Smart Email Management

# 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

# 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
  • Sending mail requires the Mail.Send delegated permission (in addition to Mail.ReadWrite). A missing Mail.Send typically returns HTTP 403 on /me/sendMail.
• Token errors: Delete ~/.microsoft_mcp_token_cache.json and re-authenticate
