Configuration

Using with Custom Puppeteer Options

You can configure Puppeteer launch options by providing a JSON string in the PUPPETEER_ARGS environment variable. This allows you to customize browser behavior without modifying the server code.

Example: Using Firefox Instead of Chrome

{
  "mcpServers": {
    "puppeteer": {
      "command": "npx",
      "args": ["-y", "github:afshawnlotfi/mcp-configurable-puppeteer"],
      "env": {
        "PUPPETEER_ARGS": "{"browser": "firefox"}"
      }
    }
  }
}

Example: Configuring Browser Window Size

{
  "mcpServers": {
    "puppeteer": {
      "command": "npx",
      "args": ["-y", "github:afshawnlotfi/mcp-configurable-puppeteer"],
      "env": {
        "PUPPETEER_ARGS": "{"defaultViewport": {"width": 1280, "height": 800}}"
      }
    }
  }
}

Standard Configuration

NPX

{
  "mcpServers": {
    "puppeteer": {
      "command": "npx",
      "args": ["-y", "github:afshawnlotfi/mcp-configurable-puppeteer"]
    }
  }
}

You can also specify a branch, tag, or commit:

{
  "mcpServers": {
    "puppeteer": {
      "command": "npx",
      "args": ["-y", "github:afshawnlotfi/mcp-configurable-puppeteer#main"]
