Automate Browser Tasks with Browser MCP and AI
Job to be done: Automate browser-based tasks and testing by connecting AI applications to a web browser
🇳🇬 Ways to use this in Nigeria
Ideas to get you started, adapt to your situation.
- Student
Use Claude to automatically fill out your NYSC registration forms on the portal, ensuring all personal and academic details are correctly entered without manual repetition.
- Small business
Automate updating product prices and stock levels across your Jumia and Konga seller accounts by having Claude navigate and input data on each platform.
- 9-5 employee
Automate the monthly submission of your travel expense claims on your company's internal portal, ensuring all fields are correctly filled from a spreadsheet.
What you’ll get
A setup where you can tell an AI assistant, in plain English, to do things in your own web browser: “fill this form”, “click submit”, “copy these prices into the other tab”. Browser MCP is the bridge that lets the AI see and control the page you have open, so it can handle repetitive web chores for you.
A heads-up before you start: this connects through something called MCP, which the free web chat at claude.ai does not support. You need a desktop app or code editor that speaks MCP, the Claude desktop app, Cursor, or VS Code. That is why this is intermediate, not beginner.
Tools you need
- Browser MCP (freemium): a browser extension plus a small local “server” that together let an AI control your browser. (“MCP”, Model Context Protocol, is just an agreed way for AI apps to plug into outside tools.)
- An MCP-capable AI client (freemium): the Claude desktop app, Cursor, or VS Code. This is the app you actually chat with; the claude.ai website will not work for this.
- VS Code (free) or Cursor (freemium): code editors that can act as the MCP client if you prefer them over the Claude app.
Steps
-
Install the Browser MCP extension: in Chrome or Firefox, go to the extension store, search “Browser MCP”, and click Add to browser. You should see its icon appear in your browser toolbar.
-
Add the Browser MCP server to your AI client: open your MCP client (Claude desktop app, Cursor, or VS Code) and add Browser MCP in its MCP/Connectors settings, following the exact snippet on browsermcp.io. This is the step that tells your AI app “you are allowed to use the browser.” You should see Browser MCP listed as an available tool or connector inside the app.
-
Confirm the connection: click the Browser MCP extension icon; it should show as connected to the server. If your client lists a “browser” tool as active, the bridge is live.
-
Give the AI a task: in the AI client’s chat, describe exactly what to do and be specific about fields and values. Vague requests fail; precise ones work:
On the page that is currently open, type "John Doe" into the First Name field, type "john.doe@example.com" into the Email field, then click the Submit button.You should watch the AI carry out each action in your browser (typing, clicking, navigating) and report back what it did.

Notes & variations
- Free-tier viability: the extension is free to install and Claude has a free tier, so you can try this without paying. Heavy automation will use more of your AI message allowance.
- Common pitfall: trying to use this with the claude.ai website. It only works through an MCP-capable app (Claude desktop, Cursor, VS Code). If nothing happens, that is usually why, or the local server is not running.
- Tip for better results: name the exact fields and the exact text to enter. “Fill out the form” is too vague; “type X into the Name field and Y into the Email field” gets reliable results.
