A programming workshop in TypeScript with Callista Enterprise, in which participants built agents with semantic search, tool use, and MCP on the Mastra framework, and which expected intermediate programming skills.

Abstract

Move beyond basic chatbots and unlock the potential of autonomous agents in your software. This hands-on workshop is tailored for developers ready to build systems that can reason, plan, and execute complex tasks. Learn how to architect, build, and evaluate practical “agentic” applications that go beyond simple text generation to perform real work. We will also describe concepts like human-in-the-loop and transparency.

What you will build

In this workshop, you’ll learn about the following concepts:

  • Some LLM theory
  • Semantic search
  • Tool use
  • Agents
  • MCP
  • Autonomous agentic workflows
  • Human in the Loop

The workshop will be an applied programming session in TypeScript using the Mastra agentic framework on an example application we have prepared for the participants.

Target audience

Software developers interested in Agentic applications. Intermediate general programming skills.

Required preparation

Bring your own computer. You will need to install Node.js, Git and an IDE of your choice. Go to https://github.com/callistaenterprise/gaia-2026-agentic-workshop.git for code download, installation, and further instructions.
