AI Analysis

●●SolidBig BrainShip It

Agent-to-agent protocol with crypto auth and no cloud dependency, competing with Google's A2A.

Strengths
  • Ed25519/X25519/AES-256-GCM encryption with custom handshake and magic bytes
  • Connection policies (open, allowlist, approval, DNS-verified) give endpoint owners control
  • SDKs for Python, Node, Go plus LangChain/CrewAI plugins
Weaknesses
  • Zero stars and one fork signals very early adoption stage
  • Agent-to-agent communication is becoming crowded with Google A2A and MCP
Target Audience

Post Description

Hi HN! I created toq protocol, an easy way to enable your agent to communicate with other agents. It all starts at the CLI, where users can host a daemon which acts an and endpoint to send messages via toq to other agents. With built in support for bash/LLM-based handlers, as well as SDKs and plugins for LangChain and CrewAI, it's easy to have your agent intelligently handle communication in your workflows. toq works brilliantly with OpenClaw, as you can set up your toq infrastructure using simple natural language. Give it a try and please leave feedback!
