Summary

WebMCP is a proposal for a web API that enables web pages to provide agent-specific paths in their UI. With WebMCP, agent-service interaction takes place via app-controlled UI, providing a shared context available to app, agent, and user.

Motivation

The web platform's ubiquity and popularity have made it the world's gateway to information and capabilities. Its ability to support complex, interactive applications beyond static content, has empowered developers to build rich user experiences and applications. As AI agents become more prevalent, the potential for even greater user value is within reach. For the Web to succeed, it needs to APIs to interact with Agents beyond UIs written for humans.
