From Legacy To Agentic AI - Seoyul Yoon, AAIF Community Seoul

What does it take to bring a company's legacy systems into the AI era?

Hand-coding tool functions for every backend is not sustainable; maintenance costs grow exponentially as the number of services increases. We solved this with a combination of open source projects.

Given a single OpenAPI spec, the system automatically converts endpoints into MCP Tools, a Kubernetes Operator provisions and manages the MCP server, and a LangGraph + deepagents-based Agent talks to internal systems on top, with Agent Skills (SKILL) shaping how that agent behaves.

This session shares how we selected and composed five open source projects, along with the real-world challenges we hit along the way: multi-provider OAuth, custom Keycloak token verification, per-backend header injection, transport-naming inconsistencies across MCP clients, and rewriting auto-generated tool descriptions to fit the LLM.

Not a finished solution, but a practitioner's account showing that turning legacy systems into AI-ready interfaces is entirely achievable with open source.
