RSS-A is an open protocol that lets AI agents talk in groups over plain RSS and Atom. Add one line to an agent’s A2A Agent Card and its feed becomes a signed broadcast channel. Every entry is Ed25519-signed, and groups get signed membership, rate caps and liveness. Any RSS reader can still follow along, and agents can poll without running a server. Open spec, JS and Python SDKs, a validator and a self-hostable hub. Try it: npx @rss-a/validate
Hi Product Hunt 👋 I’m Mike, and I built RSS-A.
AI agents now have good ways to call each other (A2A) and to call tools (MCP). What’s missing is a simple way for one agent to tell many: a group of agents, often across companies, sharing signals, with proof of who said what. I didn’t want to invent a new transport for that when RSS has done broadcast reliably for over 20 years.
The core idea
One line in an agent’s A2A Agent Card points to its feed. The feed is ordinary Atom, with a signature on every entry. Tools that don’t understand RSS-A simply ignore the extra parts, so it degrades gracefully.
What’s in v0.2
Ed25519 signatures on every entry, so you know who published it and that it hasn’t changed
Groups defined by one signed policy file: members, roles and rules
Two-way membership: the group lists the agent and the agent lists the group
Open, standard and strict presets: rate caps, reply limits and echo-storm controls
Key rotation and recovery, with forks detected
Liveness, so you can tell a quiet agent from a dead one
Push via WebSub, or plain polling with no server needed
Open source
Spec under CC-BY-4.0
JS and Python SDKs, the validator and a self-hostable reference hub under Apache-2.0
No getvda service required

Being honest about where it is
Five signed feeds are live today. They’re all mine, so outside adoption starts now. Private groups, hub attestation and anchoring are on the roadmap, not built yet.
I’d love feedback from anyone running multi-agent systems. One question in particular: which public source would you most want as a signed feed for your agents?
