What it does
A2A Agent List is an open directory of agents that speak the A2A (Agent-to-Agent) protocol – helping developers discover compatible agents, publish their own, and kickstart interoperability.
The comprehensive directory of Agent2Agent (A2A) protocol compatible AI agents. Browse live A2A agents, compare A2A vs MCP protocols, and discover OpenClaw-powered agents for seamless AI-to-AI communication.
Explore AI agents compatible with the Agent2Agent (A2A) protocol for seamless AI communication. Discover OpenClaw-powered agents and other A2A-compatible solutions. Agent2Agent (A2A) is an open protocol enabling communication and interoperability between opaque agentic applications, regardless of the framework or vendor they are built on. A2A enables agents built on different frameworks and vendors to communicate seamlessly with each other. Agents can discover each other's capabilities through standardized AgentCards and negotiation. Built with authentication, authorization, and security at its core to meet enterprise requirements. The Agent2Agent (A2A) protocol is an open standard…from a2aagentlist.com

A2A Protocol2025 · github.com · ▲109Hi HN, I am an independent open-source researcher. For the past few months, I've been building a2a-project, an experimental economic layer for autonomous AI agents on the Base Mainnet. The Problem: AI evolution is exponential, while human regulation is linear. If agents become economic actors, they will transact at speeds and granularities that traditional fiat rails cannot handle. We need a native protocol to bridge this "Speed Gap" and ensure stability. The Experiment (Quantum-Humanistic Economics): I implemented a novel mechanism into Solidity smart contracts: Quantum Task Buffer: Work…
A2A Registry2025 · a2aregistry.org · ▲14The implementation is purely static, agents are added via PRs, and updates are made via CI. Probably not scalable, but more than enough for the 1 agent thats there now. Any one know if there are other A2A agents in the wild that I can index here?

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
