MCP Dev Summit Seoul 2026

Two years ago, getting an AI agent to reach anything outside itself meant writing a whole bunch of glue code. A custom integration for every tool, every data source, every model you wanted to support. Nobody enjoyed this, and yet everybody did it anyway.

MCP was the emerging alternative - one protocol, implemented once on each side. It empowered all imaginable agents to be able to talk to anything through a standard set of conventions.

Two years later, the ecosystem around MCP is bigger than the spec itself. There are servers for nearly everything anyone would want to wire an agent into, clients across every major platform, and entire categories of capabilities that make the protocol suitable for more than just ferrying text-based data back and forth.

MCP is now the undeniable substrate most agentic workflows run on. Getting there took a couple of years, a large number of engineering debates, and the work of a community of maintainers, developers, and advocates that spans the globe. This is the story of us getting here.

To attach an MCP server to each of hundreds of Naver Cloud Platform services, every service team had to implement MCP from scratch.
We built an MCP Generator to solve this — automatically generating MCP server code from OpenAPI specs.

Then Claude's MCP Builder Skills arrived. Suddenly, anyone could build an MCP server through a few conversations with Claude. The value of the generator we had built disappeared overnight.

We had to change direction.
And the question changed with it — from "how do we make building MCP servers easier?" to "how do we operate hundreds of them?"

That's how MCP Gateway was born. It aggregates multiple MCP servers behind a single HTTP endpoint, so users can connect every cloud service tool to their AI agent with just one URL and one API key.

This talk is structured in two parts:

Part 1 — The Journey: The process of figuring out how to provide good MCP servers for hundreds of cloud services — what problems we found, what we tried, and how the arrival of MCP Builder Skills became the turning point.

Part 2 — MCP Gateway: An introduction and demo of what problems it solves today, and a look at what we're building next.
