Description

Automatically registers WebMCP tools on websites, giving AI agents structured ways to interact with any page. Detailed description: WebMCP Hub connects your browser to a community registry of WebMCP configurations. When you visit a website that has a matching config, the extension registers structured tools that AI agents can use to interact with the page — no scraping needed. How it works: - Looks up the current page's domain against the WebMCP Hub registry - If a matching config exists, registers the defined tools on the page - If no config matches, the extension does nothing Features: - Supports form filling, navigation, data extraction, and multi-step actions - Works with both traditional page loads and single-page apps - Configurable hub URL if you want to use an alternative registry Built on the open WebMCP standard.
