If you're building for the AI-first web, you already know the problem — there's no reliable way to see what WebMCP tools your site is actually exposing, whether they're valid, or how an AI agent would interact with them.
WebMCP Inspector fixes that.
What does this extension do?
WebMCP (Web Model Context Protocol) is the new W3C standard shipping in Chrome 146 that lets AI agents discover and use tools on websites. Think of it as the bridge between your site and every AI assistant, browser agent, or automated workflow that tries to interact with it.
This extension gives you a full developer console for that layer - right inside Chrome.
