About

WebMCP Validator is the fastest WebMCP Ready Checker to check if any website is ready for AI agents using the new Web MCP / WebMCP standard (Chrome 146+).

WHAT IS WebMCP?
WebMCP (Web Model Context Protocol) is a new W3C standard shipped in Chrome 146 that lets AI agents read, understand and interact with websites. Sites without WebMCP are invisible to AI agents, browser assistants, and automated workflows.

HOW IT WORKS
Just click the extension icon on any webpage. WebMCP Validator automatically detects the current URL and runs a full 19-point compliance audit — making it a powerful WebMCP Ready Checker with no copy-pasting URLs needed.

WHAT IT CHECKS
- HTTPS & server infrastructure
- AI agent access (robots.txt, llms.txt, X-Robots-Tag)
- Declarative WebMCP attributes (toolname, tooldescription, toolaction)
- Imperative WebMCP API (navigator.modelContext, registerTool)
- /.well-known/webmcp discovery manifest
- Chrome Prompt API / Built-in Gemini Nano (window.ai)

WHAT YOU GET
- Score from 0–100 with grade A to F
- Category-by-category breakdown
- Every check with a clear fix explanation
- One-click full report at validator.webmcpworld.com
- Shareable report links
- Badge for your website
- Works as a quick WebMCP Ready Checker for any domain

WHO IS IT FOR?
- Web developers checking their own sites
- SEO professionals auditing client websites
- Agencies checking competitor WebMCP readiness
- Anyone who wants to stay ahead of the AI-first web using Web MCP tools
