Pick Browser Control MCP if you need the broadest set of tools.

Pick web-eval-agent if you want the official, vendor-maintained server, and you prefer the more popular, battle-tested option.

Add Browser Control MCP

Install / run

npm install && npm run build

{
  "mcpServers": {
    "browser-control-mcp": {
      "command": "node",
      "args": [
        "/path/to/repo/mcp-server/dist/server.js"
      ],
      "env": {
        "EXTENSION_SECRET": "<secret_on_firefox_extension_options_page>",

      }
    }
  }
}

Add web-eval-agent

Install / run

curl -LSf https://operative.sh/install.sh -o install.sh && bash install.sh && rm install.sh

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "web-eval-agent": {
      "command": "uvx",
      "args": [
        "--refresh-package",
        "webEvalAgent",
        "--from",
        "git+https://github.com/Operative-Sh/web-eval-agent.git",
        "webEvalAgent"
      ],
      "env": {
        "OPERATIVE_API_KEY": "<YOUR_KEY>"
