How to Add Web Search to a Google ADK Agent with MCP (No API Key)

Google's Agent Development Kit (ADK) allows Python developers to build agents that access the live web using McpToolset and an MCP server without requiring an API key. Additionally, users can search Google Patents via Python by sending HTTP requests to a specific JSON endpoint. While official APIs are limited or paid, this method leverages the Google Patents website's internal endpoint to retrieve patent data using only the standard library, bypassing the need for official signups.
