# Microsoft Teams MCP Server
A server to schedule, reschedule, cancel Microsoft Teams interviews, and manage calendar events using the Microsoft Graph API.
## Features
- Schedule new Microsoft Teams meetings with attendees, subject, and body.
- Reschedule existing meetings by updating their start and end times.
- Cancel meetings using their event ID.
- List team calendar events with timezone support.
- Retrieve a list of IANA-supported timezones for scheduling and filtering events.
## Prerequisites
- Python 3.8 or higher.
- A Microsoft Azure AD application with Microsoft Graph API permissions (e.g., `Calendars.ReadWrite`, `User.Read.All`).
- `git` and `pip` installed on your system.
- (Optional) `uv` for running the server (install via `pip install uv`).
- (Optional) `ngrok` for exposing the local server with HTTPS (required for OpenAI API integration).
## Installation
### Using Repo Source Code
1. Clone the repository:
```bash
git clone https://github.com/alivnavc/Microsoft-Teams-Meetings-MCP-Server.git
cd Microsoft-Teams-Meetings-MCP-Server
```
2. Create and activate a virtual environment:
```bash
python -m venv venv
# On Unix/Linux/MacOS:
source venv/bin/activate
# On Windows (Command Prompt):
venv\Scripts\activate
# On Windows (PowerShell):
.\venv\Scripts\Activate.ps1
```
3. Install dependencies:
```bash
pip install -r requirements.txt
```
4. Configure environment variables:
- Create a `.env` file in the project root.
- Add your Microsoft Graph API credentials:
```env
MS_TENANT_ID=your_tenant_id
MS_CLIENT_ID=your_client_id
MS_CLIENT_SECRET=your_client_secret
MS_USER_ID=your_user_id
```
5. Run the server:
```bash
python server.py
```
Or, if using `uv`:
```bash
uv run server.py
```
6. Deploying through Docker(Optional)
Pull and Run Docker Image with .env file
```
docker pull alivnavc/microsoft-teams-mcp
docker run -d -p 4200:4200 --name teams-mcp-server --env-file /path/to/.env alivnavc/microsoft-teams-mcp
```
--env-file /path/to/.env loads environment variables from your local .env file into the container
(replace /path/to/.env with the actual path to your .env file)
Verify container is running
```
docker ps
```
### Using PIP
1. ```bash
pip install microsoft-teams-mcp==1.1.4
```
2. Use the below code
```bash
from microsoft_teams_mcp import server
server.main({
"MS_TENANT_ID": "Tenant ID",
"MS_CLIENT_ID": "Client ID",
"MS_CLIENT_SECRET": "Client Secret",
"MS_USER_ID": "User Id"
})
Run the command : python filename.py
```
## Azure AD Setup for Microsoft Graph API
To use the Microsoft Graph API, you need to register an application in Microsoft Azure AD and configure the necessary permissions. Follow these steps (summarized from [MS-Teams-setup.md](https://github.com/InditexTech/mcp-teams-server/blob/master/doc/MS-Teams-setup.md)):
1. **Register an Azure AD Application**:
- Create a Microsoft Entra ID application in the Azure portal.
- Note the application UUID (set as `MS_CLIENT_ID` in your `.env` file).
- Configure the application for either Single Tenant or Multi Tenant:
- For Single Tenant, store the tenant UUID in `MS_TENANT_ID` and set `MS_APP_TYPE=SingleTenant`.
- For Multi Tenant, adjust settings accordingly in Azure.
2. **Add a Client Secret**:
- Generate a client secret for your Azure AD application.
- Store the secret in `MS_CLIENT_SECRET` in your `.env` file.
3. **Configure Microsoft Graph API Permissions**:
- Add the `Calendars.ReadWrite` permission (and optionally `User.Read.All` for listing events) to your Azure AD application.
- Ensure the permissions are granted admin consent.
4. **Azure Bot Registration (Optional)**:
- If integrating with Microsoft Teams channels, register an Azure Bot using the same `MS_CLIENT_ID`.
- Connect the bot to the Teams channel and configure it to use the Microsoft Graph API.
For detailed instructions, refer to [MS-Teams-setup.md](https://github.com/InditexTech/mcp-teams-server/blob/master/doc/MS-Teams-setup.md).
## Usage
The server runs on `http://localhost:4200/mcp/` by default when running locally. It exposes a JSON-RPC API for interacting with Microsoft Teams meetings and calendars.
### Important Notes
- **Microsoft’s MCP Server**: Microsoft provides an MCP server for managing Teams meetings, but certain tools (e.g., scheduling with custom attendees, rescheduling, canceling, and timezone-supported calendar event listing) were found to be missing or insufficient. This project was developed to address those gaps, providing a custom implementation with the tools described below.
- **Storing Event IDs**: When scheduling a meeting using `schedule_teams_meeting`, the response includes an `event_id`. Store this ID in a database or a local file (e.g., JSON or CSV) as it is required for rescheduling (`reschedule_teams_meeting`) or canceling (`cancel_teams_meeting`) the meeting. For example, you can save the `event_id` and related metadata (e.g., meeting subject, date) in a SQLite database or a JSON file for easy retrieval.
- **OpenAI API Integration**: If you plan to integrate this server with the OpenAI API, note that OpenAI requires HTTPS endpoints. The local server (`http://localhost:4200/mcp/`) will not work with OpenAI. Use `ngrok` to expose the local server with an HTTPS URL:
1. Install `ngrok` (e.g., via `npm install -g ngrok` or download from [ngrok.com](https://ngrok.com)).
2. Run:
```bash
ngrok http 4200
```
to generate an HTTPS URL (e.g., `https://your-ngrok-subdomain.ngrok.io`).
3. Use the ngrok URL (e.g., `https://your-ngrok-subdomain.ngrok.io/mcp/`) as the endpoint for OpenAI API integration.
### Deploying on a Server
1. Deploy the application on a server (e.g., AWS EC2, Azure VM).
2. Update the server URL in your client to the server’s public IP or domain (e.g., `http://your-server-ip:4200/mcp/`).
3. Ensure HTTPS is enabled for production using a reverse proxy like Nginx.
4. Secure sensitive data (e.g., API credentials) using environment variables.
