Serverless Agents: Real-World Tooling with Strands SDK, MCP & AWS • Akshatha Laxmi • GOTO 2025

This presentation was recorded at GOTO Serverless 2025. #GOTOcon #GOTOserverless https://conferences.gotopia.tech/goto-serverless-bengaluru-2025 Akshatha Laxmi - Solution Architect at AntStack RESOURCES https://github.com/AkshathaLaxmi https://www.linkedin.com/in/akshatha-laxmi ABSTRACT In the real world, agents do not merely reason—they act. In this presentation, I walk through how to reveal real functionality to LLM agents using Strands SDK, the Model Context Protocol (MCP), and AWS Lambda. From a minimal weather tool, I'll demonstrate how to create agent tools that are modular, stateless, and production-ready. We'll walk through how MCP allows tool execution in a language-model-friendly way, and how serverless architecture makes those tools easy to deploy, scale, and maintain. The goal: building agents that don't just simulate intelligence, but actually use it.
