Building AI Agents with ADK as an MCP Client with Gemini 2.5 pro

[arjunprabhulal]

I recently published a blog demonstrating how to leverage Google’s Agent Development Kit (ADK) as a Model Context Protocol (MCP) client using Gemini 2.5 Pro, with minimal code and no modifications required on the MCP server side.

In this blog, I showcase how to build an AI agent that communicates with an existing MCP server via Server-Sent Events (SSE). I utilized the mcp-flight-search package, which provides real-time flight data through SerpAPI, to illustrate this integration.
