Content Extraction: Automatically identifies and extracts main content areas from web pages
Markdown Conversion: Converts HTML to clean, readable markdown
Pagination Support: Handles large content through pagination
Robots.txt Compliance: Respects robots.txt directives for autonomous fetching
Proxy Support: Allows routing requests through a proxy server

Requirements

Python 3.13.2 or newer
uv package manager
Playwright browsers installed

Installation

1. Install with uv (recommended)

uv pip install git+https://github.com/ThreatFlux/playwright-fetch.git
# Install Playwright browsers
uv pip exec playwright install

Alternatively, clone the repository and install:

git clone https://github.com/ThreatFlux/playwright-fetch.git
cd playwright-fetch
uv pip install -e .
# Install Playwright browsers
uv pip exec playwright install

2. Using Docker

docker build -t mcp/playwright-fetch .

Configuration

Configure for Claude.app

Add to your Claude settings:

Using uvx

"mcpServers": {
  "playwright-fetch": {
    "command": "uvx",
    "args": ["mcp-server-playwright-fetch"]
  }
}

Using docker

"mcpServers": {
  "playwright-fetch": {
    "command": "docker",
    "args": ["run", "-i", "--rm", "mcp/playwright-fetch"]
  }
}

Configure for VS Code

For manual installation, add the following JSON block to your User Settings (JSON) file in VS Code.

Using uvx

{
  "mcp": {
    "servers": {
      "playwright-fetch": {
        "command": "uvx",
        "args": ["mcp-server-playwright-fetch"]
      }
    }
  }
}

Using Docker

{
  "mcp": {
    "servers": {
      "playwright-fetch": {
        "command": "docker",
        "args": ["run", "-i", "--rm", "mcp/playwright-fetch"]
      }
    }
  }
}

Command Line Options

The server supports these command-line options:

--user-agent: Custom User-Agent string
--ignore-robots-txt: Ignore robots.txt restrictions
--proxy-url: Proxy URL to use for requests
--headless: Run browser in headless mode (default: True)
--wait-until: When to consider navigation succeeded (choices: "load", "domcontentloaded", "networkidle", "commit", default: "networkidle")

Example Usage

# Run with default settings
uv run mcp-server-playwright-fetch

# Run with a custom user agent and proxy
uv run mcp-server-playwright-fetch --user-agent="MyCustomAgent/1.0" --proxy-url="http://myproxy:8080"

# Run with visible browser for debugging
uv run mcp-server-playwright-fetch --headless=false

Debugging

You can use the MCP inspector to debug the server:

npx @modelcontextprotocol/inspector uvx mcp-server-playwright-fetch

Differences from Standard Fetch Server

This implementation differs from the standard fetch MCP server in these ways:

Browser Automation: Uses Playwright to render JavaScript-heavy pages
Content Extraction: Attempts to extract main content from common page structures
Wait Options: Configurable page loading strategy (wait for load, DOM content, network idle)
Visible Browser Option: Can run with a visible browser for debugging
