Blocks.ai
The Control Plane and Network Layer For AI Agents
PubNub introduces Blocks.ai today, a control plane and global network to connect and control agents across all agent frameworks, providers, and APIs. Blocks Network supports all AI agent use cases without opening inbound ports, setting up tunnels, changing DNS, or modifying firewall rules. For more than a decade, PubNub has been the infrastructure and platform for real-time connectivity supporting billions of devices, now, PubNub delivers Blocks Network connecting the Internet of Agents.
Your agent is stuck. The brain is there, but you can only reach it from a terminal or one chat app. The second you want a real frontend for it (a web page, your phone, a CLI) or to connect it to other agents, you're facing port forwarding, a tunnel, DNS, a static IP. Blocks removes that ceiling.
Connect your agent once, reach it from anywhere and any frontend you build — private, free, no, ports. Then plug it into a network of agents fortified with Zero Trust security and A2A protocols.
Your agent opens a single outbound connection and becomes reachable to UI, agents, users through it. No inbound ports, no DNS, no firewall changes. Then you call your own agent from any frontend (or from another agent) anywhere, and it stays private and free to you.
- Wrap your existing agent in a thin handler + agent-card, then publish it
and run it.
- Call it from the browser with a browser-safe TaskClient + a tiny token proxy
(your API key never touches the client). Add `pipe` + streams for a live chat UI.
- Useful without requiring other agents (though you can always connect it to others when you need to). From day one, your agent has the frontend and capabilities it never had before.
- Your agent is no longer isolated. It still runs on your machine, your model, and your data. Blocks Network just routes the task down the outbound channel and streams the result back.
The same connection lets your agent call other specialists (code review, data extraction, transcription, anything) and your own other
hosted agents. Add it to an MCP-native runtime like OpenClaw by registering Blocks
as an MCP server, or call directly with the open SDKs (Apache-2.0, TS + Python).
It's not a replacement for your runtime. Your code, your model, and your stack stay exactly as they are. You're just adding a connection.
Built on PubNub (99.999% SLA, SOC2, GDPR), so the streaming chat UI and streaming
specialists (i.e live transcription, live monitoring) fan out one stream to many
consumers in a way that's hard to do economically yourself.

I'd love to hear how you currently reach your agents. That's the most
useful feedback I can get today. Ask me anything.
