AGNTCon + MCPCon Europe 2026

Anthropic just announced MCP is going stateless. Most agent frameworks assume long-running, uninterrupted sessions. Real deployments face forced interruptions every hour: rate limits, auth refreshes, network partitions, process restarts, the laptop lid closing. When a session dies mid-task, most agents start over. That is not a model problem. It is a runtime design problem.

This talk covers the patterns that make agents resumable: idempotent tool calls that can safely re-execute, checkpoint-first execution that captures decisions before side effects, explicit continuation tokens that let a new session pick up an interrupted task, and the specific primitives a TypeScript runtime on Cloudflare Workers exposes to make all of this cheap. Every pattern shown is running in production on Photon, an open-source agentic tool runtime deployed to edge infrastructure.

Attendees leave with a concrete checklist: five changes to their agent architecture that make it survive the real world, not just the happy path.
