Implementing the Model Context Protocol (MCP)

This tutorial explores the Advanced Model Context Protocol (MCP) and demonstrates its application in addressing the unique challenges of modern AI systems. MCP enables real-time interaction between AI models and external data or tools, breaking the limitations of traditional models that operate in isolation.

Building Blocks of MCP

We begin by defining the fundamental components of MCP: resources, tools, and messages. These data structures facilitate the flow of information between AI systems and their external environments in a structured manner.

Resource Class

class Resource:
   uri: str
   name: str
   description: str
   mime_type: str
   content: Any = None

Tool Class

class Tool:
   name: str
   description: str
   parameters: Dict[str, Any]
   handler: Optional[Callable] = None

Message Class

class Message:
   role: str
   content: str
   timestamp: str = None
   def __post_init__(self):
       if not self.timestamp:
           self.timestamp = datetime.now().isoformat()

Implementing the MCP Server

The MCP server manages resources and tools while handling execution and retrieval operations. It supports asynchronous interaction, making it efficient and scalable for real-world AI applications.

MCP Server Class

class MCPServer:
   def __init__(self, name: str):
       self.name = name
       self.resources: Dict[str, Resource] = {}
       self.tools: Dict[str, Tool] = {}
       self.capabilities = {"resources": True, "tools": True, "prompts": True, "logging": True}
       print(f"✓ MCP Server '{name}' initialized with capabilities: {list(self.capabilities.keys())}")

Creating the MCP Client

The MCP client connects to the server, queries resources, and executes tools while maintaining a contextual memory of all interactions.

MCP Client Class

class MCPClient:
   def __init__(self, client_id: str):
       self.client_id = client_id
       self.connected_servers: Dict[str, MCPServer] = {}
       self.context: List[Message] = []
       print(f"✓ MCP Client '{client_id}' initialized")

Asynchronous Tool Handlers

We define a set of asynchronous tool handlers, including sentiment analysis, text summarization, and knowledge search, to demonstrate how the MCP system can execute diverse operations through modular tools.

Example Tool Handlers

async def analyze_sentiment(text: str) -> Dict[str, Any]:
   await asyncio.sleep(0.2)
   sentiments = ["positive", "negative", "neutral"]
   return {"text": text, "sentiment": random.choice(sentiments), "confidence": round(random.uniform(0.7, 0.99), 2)}

Running the MCP Demonstration

We bring everything together into a complete demonstration where the client interacts with the server, fetches data, runs tools, and maintains context. This showcases the full potential of MCP in integrating AI logic with external knowledge and computation.

Conclusion

The Model Context Protocol (MCP) represents a significant advancement in AI system architecture, enabling dynamic interoperability and modular, tool-augmented intelligence. By implementing MCP, organizations can build adaptive AI systems that can think, learn, and connect beyond their original confines.
