Ghostlight MCP server

Ghostlight is a helper that lets your AI work inside the browser you already use, with your logins already in place. It opens a special sky-blue tab group so you can watch every step, pause it, or take over. It is handy if you want an assistant to handle web chores without setting up a fresh, empty browser.

What this MCP server does

You ask your AI to do something in the browser, like read a page or fill in a form. Your AI passes that request to Ghostlight, which carries out the browser steps in a sky-blue tab group inside the browser window you chose. It can move between tabs, wait for pages to load, upload files, and answer popups. After each action it tells you plainly what happened, what changed, and whether it is safe to run again. If something goes wrong, it suggests a next step instead of guessing.

What you can do with it

• Open a web page in a new Ghostlight tab and summarize it
• Fill in a form and submit it while you watch
• Upload a file to a website
• Click buttons and links by meaning, not by guessing coordinates
• Take a screenshot of a page
• Follow a popup or a new tab that opens during a task
• Check what failed by looking at page state, console messages, and network requests

Try asking your AI

• “Open example.com in a new Ghostlight tab, summarize the page, and tell me which tab you used. Do not click or type anything.”
• “Go to our supplier portal, log in using the session that is already open, and download last month's invoice as a PDF.”
• “Fill in the contact form on this page with my name and email, then stop before submitting so I can check it.”
• “Something went wrong on the checkout page earlier. Open it again and tell me what the console and network errors say.”

What it gives back to you

You get a short, plain answer in the chat: what it did, what changed on the page, and whether it is safe to repeat. It can also give you page summaries, screenshots, and lists of elements it found. When something is uncertain, it says so instead of pretending. It never writes its answer using the page's own words, so you can trust the description.

Who it's for

Anyone who wants an AI to handle everyday web tasks inside their own logged-in browser, especially office workers, researchers, and people testing web workflows.
