*A Python MCP server using browser fingerprint impersonation, headless Chrome,
and multi-tier anti-detection to reliably fetch web pages for AI agents —
published on PyPI with CI/CD pipeline and test coverage.*

## What is this?

`web-fetch-mcp` is an [MCP](https://modelcontextprotocol.io) server that lets AI
assistants (like Claude, Cursor, or any MCP-compatible client) fetch web pages
**reliably**.

### The problem it solves

When an AI agent fetches a web page, many sites return a CAPTCHA, a JavaScript
challenge, or a login wall — but still send HTTP status `200 OK`. A naive
fetcher hands this garbage to the AI, which then reasons from nonsense.

### How this tool fixes it

`web-fetch-mcp` **detects** when a site returns a block page instead of real
content, and either:

1. **Escalates** to a stronger fetching strategy (there are 3 tiers), or
2. **Fails loudly** with a clear error (`FetchBlocked`) — never silently
   returning junk.

> **Status:** Alpha. Core logic is tested, but real-world bypass benchmarks are
> in progress.

## Installation

**Requirements:** Python 3.11+

```bash
pip install web-fetch-mcp
```

That's it. This installs the `web-fetch-mcp` command on your system.

---

## Quick Start

### 1. Run the server

```bash
web-fetch-mcp
```

This starts the MCP server in the background. It doesn't show anything on its
own — your AI client talks to it automatically.

### 2. Register with your MCP client

Add this to your MCP client's configuratio…
