W2A, an Open Protocol for Agent Sensors

·2026.04.29 00:46

Key point

W2A has released a sensor protocol for local agents.

Details

World2Agent (W2A) is an open protocol that standardizes the perception layer for local agents.

It reduces the problem of various scripts and cron jobs injecting events in different JSON formats, allowing the same sensor signals to be reused even when switching frameworks.

  • Can be self-hosted
  • No SaaS
  • No telemetry
  • TypeScript SDK provided
  • Apache 2.0 license

The protocol does not build in routing or prioritization. Sensors only publish signals, and the same signal can be repurposed across Claude Code, a Slack bot, or a dashboard.

A plugin path for Claude Code and a Hacker News sensor example have also been released. It can also be connected to local runtimes such as Ollama or LiteLLM.
