## 📝 Zulip Terminology: Streams vs Channels
In Zulip, **"streams"** and **"channels"** refer to the same concept:
- **Stream** = Official Zulip terminology (used in API, tools, interface)
- **Channel** = Common term from Slack/Discord/Teams
- **Same thing** = Conversation spaces where teams discuss topics
This MCP server uses "stream" to match Zulip's official documentation and API.
## Installation & Setup
### Prerequisites
- Node.js 18+ with npm
- TypeScript 5+
- Access to a Zulip instance (e.g., https://your-organization.zulipchat.com)

### Quick Start
1. **Clone and install dependencies:**
```bash
git clone <repository-url>
cd zulip-mcp-server
npm install
```
2. **Configure environment variables:**
```bash
cp .env.example .env
# Edit .env with your Zulip credentials
```
3. **Build and run:**
```bash
npm run build
npm start
```
### Environment Configuration
Create a `.env` file with your Zulip credentials:
```env
ZULIP_URL=https://your-organization.zulipchat.com
ZULIP_EMAIL=your-bot-email@yourcompany.com
ZULIP_API_KEY=your-api-key-here
NODE_ENV=production
```
