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 PDFMonkey?
PDFMonkey adds an MCP server and Node.js SDK, so assistants can generate its documents.
An October 26 catch-up lists what shipped since summer. New items are zero-downtime API key rotation with a two-day overlap, snippet folders, an official Node.js SDK and an MCP server for Claude, Cursor and other AI assistants. Zapier document generation no longer races the 30-second limit, and n8n node 1.0 is now verified by n8n. February's visual builder remains the largest change in this window.

Ably
7.5INFRA · APIS
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.
PDFMonkey
2.5INFRA · APIS
PDFMonkey adds an MCP server and Node.js SDK, so assistants can generate its documents.
◆ Current state
An October 26 catch-up lists what shipped since summer. New items are zero-downtime API key rotation with a two-day overlap, snippet folders, an official Node.js SDK and an MCP server for Claude, Cursor and other AI assistants. Zapier document generation no longer races the 30-second limit, and n8n node 1.0 is now verified by n8n. February's visual builder remains the largest change in this window.
◆ Where it's heading
The two-audience pattern holds, and a third has joined: AI assistants calling PDFMonkey directly. The builder serves non-developers, while the SDKs, key rotation and automation fixes serve teams with PDFMonkey in production. Work on Zapier and n8n shows attention to where documents are actually triggered.
◆ Prediction
Expect more integration and SDK coverage, given the Ruby and Node.js releases and the n8n and Zapier work. How MCP use develops is not readable from a single catch-up post.
