Automate browser tasks with an AI agent

Browser automation servers hand an agent a real browser. It can open a page, read the accessibility tree, click buttons, fill in forms, and take screenshots, then decide on the next step from what it sees. Developers use them to reproduce bugs, write end-to-end tests, and check a deploy without opening a window themselves. Most are built on Playwright or Puppeteer and run headless on your machine, while hosted options handle logins and scale in the cloud. Give the agent a test account rather than your personal sessions.

Setup

How to set it up

  1. Pick a server. Aether WCAG Scanner is the strongest match. Check its tools and the API keys it needs on its page.
  2. Copy the config for your client. Open the install guide for Claude Desktop, Claude Code, Cursor, or VS Code, and paste the generated block into the client's config file. The client guides show where each config file lives.
  3. Restart and try a prompt. Restart the client so it loads the server, then paste one of the example prompts above.
FAQ

Questions about browser automation

What is the best MCP server for browser automation?

Aether WCAG Scanner ranks first here with a trust score of 70/100, followed by browser-compat-mcp-server (70) and mcp (70). Servers that name the topic directly come first, each group ordered by the public trust score, which nobody can pay for. See the methodology for how it is calculated.

How do I set up Aether WCAG Scanner in Claude or Cursor?

Open the install guide for Claude Desktop or Cursor, copy the generated config into the client's config file, add any API keys the server asks for, then restart the client. The client guides cover VS Code, Claude Code, Windsurf, and more.

Can I use a hosted server instead of installing one locally?

2 of the 12 servers listed here can connect remotely over HTTP, so there is nothing to run on your machine: browser-compat-mcp-server, mcp. The rest run locally over stdio.
