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 Infisical?

Infisical's Agent Vault learns to find services, with database and SSH access built in.

Infisical released v0.167.9 and v0.167.10 on November 13. v0.167.9 is a large release: Agent Vault adds service discovery, service descriptions, a built-in skill, PostgreSQL, MySQL and SSH services, MCP templates for six more providers and services packaged into access bundles. It also publishes KMS public keys as a JWKS, pins outbound connections to validated IPs and applies approval policies to certificate renewals. v0.167.10 lets users request a narrower path inside a glob access policy.

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.

Infisical's Agent Vault learns to find services, with database and SSH access built in.

◆ Current state

Infisical released v0.167.9 and v0.167.10 on November 13. v0.167.9 is a large release: Agent Vault adds service discovery, service descriptions, a built-in skill, PostgreSQL, MySQL and SSH services, MCP templates for six more providers and services packaged into access bundles. It also publishes KMS public keys as a JWKS, pins outbound connections to validated IPs and applies approval policies to certificate renewals. v0.167.10 lets users request a narrower path inside a glob access policy.

◆ Where it's heading

Agent Vault, Infisical's credential broker for AI agents, gets new capability in nearly every release, moving from proxy tokens and MCP allowlists toward a catalog of services agents can discover and reach. Alongside it, the PKI, KMS and access-request features keep filling enterprise gaps. Releases come every two to four days.

◆ Prediction

Expect more Agent Vault service types and MCP templates, and access bundles to become the main way Agent Vault permissions are granted.
