MCP Dev Summit Seoul 2026

Building an MCP server is easy to demo and hard to operate. Once a server sits between an agent and real systems, questions about transport choice, cancellation, timeouts, concurrency, schema evolution, and tool safety show up fast.

This talk walks through building a production-minded MCP server in Go. It covers how to model tools and resources with Go types, choose between stdio and HTTP-based transports, handle concurrent tool calls without shared-state bugs, and add logging, metrics, and failure boundaries that make incidents debuggable. It also compares the current Go MCP landscape: the official Go SDK, community libraries like mcp-go, and what the emerging ecosystem still lacks compared to the Python and TypeScript stacks.

The examples come from MCP server patterns for CI/CD and platform workflows, where reliability matters because the server sits in the critical path between an AI agent and deployment infrastructure. Attendees will leave with a concrete set of patterns for shipping Go-based MCP services that are reliable enough for production, not just demos.
