## 💡 Usage Examples

### MCP Protocol Usage

#### Stdio Transport (Traditional)
```python
# Example using the MCP Python SDK client
import asyncio
from mcp.client.session import ClientSession
from mcp.client.stdio import StdioServerParameters, stdio_client

async def main():
    server_params = StdioServerParameters(
        command="uv",
        args=["run", "todo-mcp-server", "serve"]
    )
    
    async with stdio_client(server_params) as (read, write):
        async with ClientSession(read, write) as session:
            await session.initialize()
            
            # Create a task
            result = await session.call_tool("create_task", {
                "title": "Complete project documentation",
                "description": "Write comprehensive docs",
                "priority": "high"
            })
            print(f"Created task: {result}")

asyncio.run(main())
```

#### HTTP Transport (AI Clients)
```python
# Example using StreamableHttp transport for AI clients
import asyncio
from mcp import ClientSession
from mcp.client.streamable_http import streamablehttp_client

async def main():
    # Connect to FastMCP server
    async with streamablehttp_client("http://localhost:8000/mcp") as (read, write, _):
        async with ClientSession(read, write) as session:
            await session.initialize()
            
            # List available tools
            tools = await session.list_tools()
            print(f"Available tools: {[tool.name for tool in tools.tools]}")
            
            # Create a task
            result = await session.call_tool("create_task", {
                "title": "AI-generated task",
                "description": "Task created by AI client via HTTP",
                "priority": "medium"
            })
            print(f"Created task: {result}")

asyncio.run(main())
```

#### Hierarchical Task Management
```python
# Create parent task via MCP
parent_result = await mcp_client.call_tool("create_task", {
    "title": "Implement User Management System",
    "description": "Complete user management functionality",
    "priority": "high",
    "tags": ["epic", "user-management"]
})

parent_id = parent_result["task"]["id"]

# Create child tasks
child_tasks = [
    {
        "title": "Design User Database Schema",
        "description": "Create tables for users, roles, permissions",
        "priority": "high",
        "parent_id": parent_id,
        "tags": ["database", "design"]
    },
    {
        "title": "Implement User Authentication",
        "description": "Add login/logout functionality",
        "priority": "medium", 
        "parent_id": parent_id,
        "tags": ["auth", "security"]
    }
]

for task_data in child_tasks:
    await mcp_client.call_tool("create_task", task_data)
```

### HTTP REST API Usage

```python
import httpx

# Create task via REST API
async with httpx.AsyncClient() as client:
    response = await client.post("http://localhost:8000/tools/create_task", json={
        "title": "REST API Task",
        "description": "Task created via HTTP API",
        "priority": "medium",
        "tags": ["api", "http"]
    })
    
    result = response.json()
    print(f"Task created: {result['result']}")
```

### Server-Sent Events (SSE) Usage

```javascript
// Connect to SSE endpoint for real-time updates
const eventSource = new EventSource('http://localhost:8000/events');

// Listen for task creation events
eventSource.addEventListener('task_created', function(event) {
    const data = JSON.parse(event.data);
    console.log('New task created:', data.task.title);
});

// Listen for task updates
eventSource.addEventListener('task_updated', function(event) {
    const data = JSON.parse(event.data);
    console.log('Task updated:', data.task.title);
});

// Listen for tool executions
eventSource.addEventListener('tool_executed', function(event) {
    const data = JSON.parse(event.data);
    console.log('Tool executed:', data.tool);
});
```

### WebSocket Usage

```javascript
// Connect to WebSocket for bidirectional communication
const ws = new WebSocket('ws://localhost:8000/ws');

ws.onopen = function() {
    console.log('WebSocket connected');
    
    // Execute tool via WebSocket
    ws.send(JSON.stringify({
        type: 'tool_call',
        tool: 'create_task',
        parameters: {
            title: 'WebSocket Task',
            description: 'Task created via WebSocket'
        }
    }));
};

ws.onmessage = function(event) {
    const data = JSON.parse(event.data);
    
    if (data.type === 'tool_result') {
        console.log('Tool result:', data.result);
    } else if (data.type === 'tool_executed') {
        console.log('Tool executed by another client:', data.tool);
    }
};
```

### Streaming Operations

```python
import httpx

# Stream task creation with progress updates
async with httpx.AsyncClient() as client:
    async with client.stream("POST", "http://localhost:8000/stream", json={
        "tool": "create_task",
        "parameters": {
            "title": "Streaming Task",
            "description": "Task with streaming progress"
        }
    }) as response:
        async for chunk in response.aiter_text():
            if chunk.startswith('data: '):
                data = json.loads(chunk[6:])
                
                if data.get('status') == 'processing':
                    print(f"Progress: {data.get('progress', 0)}%")
                elif data.get('status') == 'completed':
                    print(f"Task created: {data.get('result')}")
```

### Advanced Task Filtering

```python
# Search for high-priority authentication tasks
search_result = await mcp_client.call_tool("filter_tasks", {
    "priority": ["high", "urgent"],
    "tags": ["authentication"],
    "status": ["pending", "in_progress"],
    "limit": 50
})

# Get task statistics
stats = await mcp_client.call_tool("get_task_statistics", {})
print(f"Total tasks: {stats['statistics']['total_tasks']}")
print(f"Completion rate: {stats['statistics']['completion_rate']:.1%}")
```

### Bulk Operations

```python
# Update multiple tasks to completed status
task_ids = ["task-001", "task-002", "task-003"]
await mcp_client.call_tool("bulk_status_update", {
    "task_ids": task_ids,
    "status": "completed"
})

# Get complete hierarchy for reporting
hierarchy = await mcp_client.call_tool("get_task_hierarchy", {
    "root_id": parent_id
})
```
