WebMCP

A browser-context approach for exposing website actions as structured tools for AI agents.

Definition

WebMCP proposes structured website tools that agents can discover and use in a browser context. It is especially relevant for forms, navigation, support workflows, and website state management.

Why it matters

WebMCP can make websites more agent-readable, but public browser-exposed tools need tight permissions and visible user context.

How HARNEXA uses it

HARNEXA treats WebMCP as a readiness layer until approval, support, audit, and revocation boundaries are defined.

FAQ

Questions this definition answers.

Does WebMCP support headless tool calls?

Chrome's public WebMCP documentation frames it around browser or webview context, not headless public execution.

What HARNEXA WebMCP tools would come first?

Readiness, navigation, evidence packet, and structured intake helpers before any commerce execution tool.
