AGNTCon + MCPCon Japan 2026

AI agents have long been capable of interacting with the web, relying on brittle DOM scrapers and heavy browser automation has kept these workflows slow and prone to failure. We will explore how the WebMCP shifts agentic web interaction from merely functional to highly performant and efficient by providing a standardized, machine-readable layer for context sharing and action execution. WebMCP eliminates the friction and overhead of legacy automation techniques.

The next leap in agent engineering is not bigger models. It's reusable skills.

Today, many agents repeatedly spend tokens rediscovering the same workflow every time a task appears. Whether it's code reviews, incident analysis, documentation generation, or research tasks, the agent often re-plans work it has already solved before.

This talk explores how agent skills are emerging as reusable workflow primitives that package expertise, decision-making patterns, and execution steps into portable capabilities. Instead of relying on increasingly large prompts, teams can teach agents repeatable workflows once and reuse them across tasks, products, and environments.


Key Takeaways

- Why prompts don't scale for repetitive work
- Skills as reusable workflow contracts
- Reducing token consumption through workflow reuse
- How skills and MCP work together
- Building self-improving agent systems

Open protocols like MCP and A2A let you combine agents and tools from different teams into one system.

But at company-wide scale, new challenges arise: who can access the system, who can call which agent, whether it fails safely, and whether it follows internal governance. Coding agents now write most of the code, so the spec we give them shapes the whole system's quality.

We'll share how we tackled this from two sides on a company-wide MCP × A2A platform.

Architecture side: where to declare per-agent access, how to handle attribute-based authorization, how to split the write and read sides of authorization data, and how to stay fail-closed, mapped to standard authorization-control models.

Development-process side: a multi-stage review of the requirements given to coding agents, covering format, clarity, cross-walk with external standards, and adversarial testing. This catches auth and governance issues, plus input validation flaws and data leakage, before code is written.

You'll come away with ideas for an interoperable MCP/A2A authorization layer, a reusable way to gather enterprise-grade requirements, and a view of specs themselves as security assets.
