WebMCP is a proposed web standard that enables websites to expose structured, callable tools directly to AI agents through a new browser API. Developed jointly by engineers at Google and Microsoft and incubated through the W3C's Web Machine Learning Community Group, WebMCP allows you to wrap your existing client-side JavaScript logic into agent-readable tools without re-architecting your web pages. Instead of AI agents relying on screen scraping or DOM manipulation to interact with websites, WebMCP provides a standardized way for agents to discover and invoke specific functions with defined schemas, ensuring more reliable and precise interactions.
