How to Connect Real-Time Stock Data to Your AI Agent (MCP Tutorial)

The provided code demonstrates how to integrate Claude, an AI assistant from Anthropic, with external tools to fetch real-time data and enhance its responses. Specifically, it shows how to query the current stock price of Apple (AAPL) by leveraging a tool called get_stock_price that interacts with an external API.

Here's a breakdown of what the code does:

1. Importing Required Libraries: The script starts by importing necessary libraries such as Anthropic for interacting with Claude and any other required packages like requests if needed for API calls.

2. Defining Tools: A list of tools is defined, where each tool has a name (get_stock_price), description, input schema (specifying what inputs the function expects), and output schema (though not explicitly used in this example).

3. User Query: The script sets up an initial user query asking for the current price of Apple stock.

4. Calling Claude with Tools: It then calls Claude's API (client.messages.create) with the defined tools, passing along the user question as input to see how Claude responds.

5. Processing Tool Use Response:

   • The script checks if Claude used any tool in its response by iterating through the blocks of content returned
