# MCP Protocol Integration Implementation Summary
Duration: 30 minutes

## 1. Implementation Overview

### Core Files Implemented
1. **Mock Multi-Agent System** (`examples/mcp_example/mock_multi_agent.py`)
   - Implemented a multi-agent system with Calculator and Stock Analyst agents
   - Uses MCP servers for math and stock operations
   - Created interactive system for testing

2. **Test Integration** (`examples/mcp_example/test_integration.py`)
   - Basic integration test setup with MCP server connection
   - Tests math operations through MCP protocol

3. **MCP Integration Core** (`swarms/tools/mcp_integration.py`)
   - Implemented core MCP server classes (MCPServerStdio, MCPServerSse)
   - Added tool schema handling and batch operations

### Testing Implementation
Located in `tests/tools/test_mcp_integration.py`:

1. Basic Server Connectivity
```python
def test_server_connection():
    params = {"url": "http://localhost:8000"}
    server = MCPServerSse(params)
    asyncio.run(server.connect())
    assert server.session is not None
```

2. Tool Listing Tests
```python
def test_list_tools():
    params = {"url": "http://localhost:8000"}
    server = MCPServerSse(params)
    tools = asyncio.run(server.list_tools())
    assert isinstance(tools, list)
```

3. Tool Execution Tests
```python
def test_tool_execution():
    params = {"url": "http://localhost:8000"}
    function_call = {
        "tool_name": "add",
        "arguments": {"a": 5, "b": 3}
    }
    result = mcp_flow(params, function_call)
    assert result is not None
```

## 2. Implementation Details

### MCP Server Integration
1. Added MCP server parameters to Agent class:
```python
mcp_servers: List[MCPServerSseParams] = []
```

2. Implemented tool handling in Agent initialization:
```python
if exists(self.mcp_servers):
    self.mcp_tool_handling()
```

3. Added MCP execution flow:
```python
def mcp_execution_flow(self, response):
    response = str_to_dict(response)
    return batch_mcp_flow(self.mcp_servers, function_call=response)
```

## 3. Testing Results

### Interactive Testing Session
From `mock_multi_agent.py`:

```
Multi-Agent Math System
Enter 'exit' to quit

Enter a math problem: calculate moving average of [10,20,30,40,50] over 3 periods

Results:
Calculator: Math operation processing
StockAnalyst: Moving averages: [20.0, 30.0, 40.0]
```

## 5. Next Steps

2. Add more complex MCP server interactions
3. Improve error handling and recovery
4. Add documentation for custom tool implementations

## 6. Usage Example
```python
from swarms import Agent
from swarms.tools.mcp_integration import MCPServerSseParams

# Configure MCP server
server = MCPServerSseParams(
    url="http://0.0.0.0:6274",
    headers={"Content-Type": "application/json"}
)

# Initialize agent with MCP capabilities
agent = Agent(
    agent_name="Math-Agent",
    system_prompt="You are a math processing agent",
    mcp_servers=[server],
    max_loops=1
)

# Run the agent
response = agent.run("Use the add tool to add 2 and 2")
print(response)
```
