## About

Experimental. WebMCP is still evolving, so small API and behavior changes should be expected.

Zod-first. Define inputs with Zod and get full type inference in handlers

JSON Schema fallback. Pass raw JSON Schema when you don't want Zod

Built-in polyfill. Uses a lightweight polyfill when native WebMCP is unavailable

A fully playable Wordle clone that showcases webmcp-react hooks. Tools dynamically register and unregister as the game moves through phases (idle, playing, won/lost), and guesses can be made via keyboard or through a connected MCP agent. Includes a DevPanel for inspecting tool state and an easy-mode toggle that enables a hint tool. Install the Chrome extension to bridge tools to AI clients like Claude and Cursor.

This repo ships with agent skills that can set up webmcp-react and scaffold tools for you. Install them with the skills CLI :

This library provides React bindings for that API. <WebMCPProvider> installs a polyfill (skipped when native support exists), and each useMcpTool call registers a tool that agents can discover and execute.

Once Chrome supports this bridging natively, I'll deprecate the extension.
