Introducing WebMCP for agent-website interaction

WebMCP embeds a server in client-side JavaScript, allowing agents to interact with websites deterministically through declarative or imperative APIs.

#3about 6 minutes

Establishing a formal contract between agents and websites

WebMCP provides a formal contract for agent interaction, moving beyond inefficient and adversarial web scraping to a more cooperative model.

#4about 3 minutes

Improving agent efficiency and website security

WebMCP significantly reduces agent token consumption compared to DOM parsing and provides a secure interaction model by limiting agent actions to predefined tools.

#5about 2 minutes

Standardization efforts and broad industry support

WebMCP is becoming an official web standard through a W3C proposal with active participation from Google, Microsoft, and Mozilla.

#6about 4 minutes

Reusing testing logic and integrating with frameworks

Developers can repurpose the logic from existing testing scripts for WebMCP and integrate it into modern frameworks like React using an imperative API.
