What is Retool?
Retool's MCP server is generally available, so AI tools can reach your Retool org directly.
On November 11 Retool made its MCP server generally available, added Claude Fable 5.2 to its model list and turned on web search for AI app building and in-app functions. The week before, MongoDB Atlas and Snowflake gained OAuth sign-in for cloud instances, workflows learned to run as a permission group and Microsoft SQL 1.0/2.0 were retired.
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.

Retool

Retool's MCP server is generally available, so AI tools can reach your Retool org directly.
◆ Current state
On November 11 Retool made its MCP server generally available, added Claude Fable 5.2 to its model list and turned on web search for AI app building and in-app functions. The week before, MongoDB Atlas and Snowflake gained OAuth sign-in for cloud instances, workflows learned to run as a permission group and Microsoft SQL 1.0/2.0 were retired.
◆ Where it's heading
Retool is opening itself to outside agents through MCP while its own AI builder gets new models and live web data. The connection work underneath, with OAuth instead of stored database users, cuts setup and secrets for the data those agents touch.
◆ Prediction
Expect more resources to move to OAuth sign-in and the MCP server to gain write or app-building tools; the entries do not yet say what the GA server can do.
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.
