This guide covers the changes needed when upgrading from AI SDK v5 to v6 with @cloudflare/ai-chat.

Agent

Agents emit structured events for every significant operation — RPC calls, state changes, schedule execution, workflow transitions, MCP connections, and more. These events are published to diagnostics channels and are silent by default (zero overhead when nobody is listening).

Agent

Send browser push notifications from your agent — even when the user has closed the tab. By combining the agent's persistent state (for storing push subscriptions), scheduling (for timed delivery), and the Web Push API, you can reach users who are completely offline.

Agent

The Agents SDK provides a built-in queue system that allows you to schedule tasks for asynchronous execution. This is particularly useful for background processing, delayed operations, and managing workloads that don't need immediate execution.

Readonly connections restrict certain WebSocket clients from modifying agent state while still letting them receive state updates and call non-mutating RPC methods.

Agent

The AIChatAgent class provides automatic resumable streaming out of the box. When a client disconnects and reconnects during an active stream, the response automatically resumes from where it left off.

Agent

Retry failed operations with exponential backoff and jitter. The Agents SDK provides built-in retry support for scheduled tasks, queued tasks, and a general-purpose this.retry() method for your own code.

This guide explains how requests are routed to agents, how naming works, and patterns for organizing your agents.

Agent

Schedule tasks to run in the future — whether that's seconds from now, at a specific date/time, or on a recurring cron schedule. Scheduled tasks survive agent restarts and are persisted to SQLite.

Model Context Protocol servers, like every other web application, need to be secured so they can be used by trusted users without abuse. The MCP spec uses the OAuth 2.1 standard for authentication between MCP clients and servers.

Agent

Send messages and trigger LLM responses from the server without a human action. Use this for scheduled follow-ups, queue processing, email-triggered responses, and autonomous agent workflows.

Agent

The Session API provides persistent conversation storage for agents, with tree-structured messages, context blocks, compaction, full-text search, and AI-controllable tools. By default it uses Durable Object SQLite; external Postgres storage is also available for apps that need shared database access, analytics, or…

Agents provide built-in state management with automatic persistence and real-time synchronization across all connected clients.

Agent

Sub-agents are child Durable Objects colocated under a parent agent. Each sub-agent has its own isolated SQLite storage and its own WebSocket connections, but shares the parent's machine and is spawned, listed, and torn down through the parent. Clients reach a sub-agent directly via a nested URL; inside an agent…

Agent

Receive webhook events from external services and route them to dedicated agent instances. Each webhook source (repository, customer, device) can have its own agent with isolated state, persistent storage, and real-time client connections.

Integrate Cloudflare Workflows with Agents for durable, multi-step background processing while Agents handle real-time communication.
