AGNTCon + MCPCon Japan 2026

A working agent ends up talking to a lot of things: a handful of MCP servers, two or three LLM providers, maybe another agent. Each one is a separate integration you wired in yourself, with its own auth and its own logging, or its own lack of it. Nothing sees all of it at once.

agentgateway is trying to be the thing that does. It's an open-source Rust proxy, an Agentic AI Foundation project as of this year, that sits in front of MCP, LLM, and A2A traffic together. The talk is mostly the gateway running on screen.

Four separate MCP servers go behind one endpoint and show up to the agent as a single list of tools. Claude Code connects to that one address and never finds out the tools live in four different places. One short rule, and a tool you don't want exposed stops showing up at all: not blocked, just never offered. Point the model traffic through the same gateway and a provider can drop mid-demo without the agent noticing, the whole thing readable as one trace.

Underneath the protocols, the idea is simple: an agent reaching into the world should go through one door someone is watching, not a hundred that nobody is. Building that door is what the talk is about.
