# mcp-handler新增WebMCP实验性支持，一行script标签即可暴露工具

Vercel的mcp-handler现已实验性支持WebMCP——一项提议中的Web标准，用于向浏览器内智能体暴露工具。用户只需在网站中添加一个script标签，现有的MCP工具即可在浏览器中使用。通过将工具添加到experimental_webMcp对象中即可选择启用。这为开发者提供了一种在网页中直接集成AI智能体工具的新方式。

## English Version

**mcp-handler Adds Experimental WebMCP Support for In-Browser Agents**

Vercel's mcp-handler now has experimental support for WebMCP, a proposed web standard for exposing tools to in-browser agents. Adding a single script tag to a site makes existing MCP tools available in the browser. Developers opt tools in by adding them to the experimental_webMcp object. This offers a new way to integrate AI agent tools directly into web pages.
