H/Ai Browser MCP server

H/Ai lets your AI coding assistant use the browser tab that is already open inside VS Code. You and the AI share the same tab, so you can watch it click around, and jump in whenever you want. It is handy if you build web pages and want help testing them without switching windows.

What this MCP server does

You ask your AI to check something in your web app, like whether a signup form works. The AI uses this helper to open the page in the VS Code browser tab. The helper clicks, types and scrolls like a real person would. It reads the page, the console messages and the network activity, and takes screenshots. Then it tells you what it found, and you can take over the tab at any moment.

What you can do with it

• Open a page and check that a form or button works
• Click, type, scroll and drag on the page for you
• Take screenshots of the page or a single element
• Read console errors and network requests
• Point at an element and jump to the code that made it
• Work with several browser tabs at once
• Wait for text to show up, then highlight it so you can see it

Try asking your AI

• “Open http://localhost:5173 and check the signup form works”
• “Click the checkout button and tell me if any errors show up in the console”
• “Take a screenshot of the pricing section and describe what you see”
• “Wait for the loading text to disappear, then click the first product”

What it gives back to you

You get back plain answers in the chat, like what the AI saw and did. It can also show you screenshots, lists of console messages, and lists of network requests. If it changed something on the page, like typing in a field or clicking a button, it tells you that too. Everything appears right in your conversation.
