WebMCP: Teaching Your Website to Talk to AI Agents

Right now, when an AI agent uses a website, it squints at the screen like a person would: reads the pixels, guesses which button is checkout, clicks, and hopes. It’s slow, brittle, and it breaks the moment you move a div. WebMCP flips that around. Instead of the agent guessing what your site can do, your site just tells it, in plain, structured tools the agent can call directly. It’s an early web standard, it’s in Chrome right now behind a trial, and once you see it you’ll want to add a tool to your own site in about ten minutes. Here’s how it works and why it matters.
