What is Ably?

Ably's AI Transport hits 1.0 and plugs straight into Vercel's useChat with resumable streams.

Ably is repositioning its realtime pub/sub network as the transport layer for AI agent output. AI Transport JS 1.0 runs on ordinary Pub/Sub channels and ships adaptors for the Vercel AI SDK, OpenAI Responses API and AG-UI, plus a useChat transport that resumes a stream after a reload. It lands a week after the switch to monthly-active-user pricing and breaking SDK majors that split every client into device and server packages.

What is NetBird?

NetBird's v0.83 candidate turns its management API into an MCP server for AI tools.

NetBird v0.82 candidates removed MySQL in favor of PostgreSQL and deprecated Rosenpass. The first v0.83 candidate, on November 9, serves the management REST API as an MCP server behind an OAuth 2.1 broker, with a consent page that leaves write access unticked by default and MCP sign-ins recorded in the activity log. It also reports LLM token usage from the proxy, renews cached ACME certificates and adds profile ownership checks to the client.

7.5

Ably's AI Transport hits 1.0 and plugs straight into Vercel's useChat with resumable streams.

◆ Current state

Ably is repositioning its realtime pub/sub network as the transport layer for AI agent output. AI Transport JS 1.0 runs on ordinary Pub/Sub channels and ships adaptors for the Vercel AI SDK, OpenAI Responses API and AG-UI, plus a useChat transport that resumes a stream after a reload. It lands a week after the switch to monthly-active-user pricing and breaking SDK majors that split every client into device and server packages.

◆ Where it's heading

The November releases fit one plan: split clients so MAU billing can count end users, then make the AI layer a thin adaptor on top of the same channels used for chat, presence and LiveObjects. Server-side additions in Java and JS (HTTP LiveObjects, channel pools, a Temporal plugin) point at agent backends as the intended publisher.

◆ Prediction

Expect more agent framework adaptors and server SDKs reaching AI Transport parity, with Chat and LiveObjects examples built around agents joining human conversations.

NetBird's v0.83 candidate turns its management API into an MCP server for AI tools.

◆ Current state

NetBird v0.82 candidates removed MySQL in favor of PostgreSQL and deprecated Rosenpass. The first v0.83 candidate, on November 9, serves the management REST API as an MCP server behind an OAuth 2.1 broker, with a consent page that leaves write access unticked by default and MCP sign-ins recorded in the activity log. It also reports LLM token usage from the proxy, renews cached ACME certificates and adds profile ownership checks to the client.

◆ Where it's heading

After a storage and hardening cycle, NetBird is opening its control plane to AI agents, with guardrails visible in the same release: OAuth, read-only defaults and audit logging. The proxy reporting LLM token usage points to NetBird also positioning itself in front of AI traffic.

◆ Prediction

Expect v0.83 release candidates to refine MCP permissions and catalog coverage, with LLM gateway metrics expanding in the proxy.
