Features

Tools

The server provides four specialized tools:

• get-raw-text: Extracts raw text content directly from URLs without browser rendering

  • Arguments:
    • url: URL of the target web page (text, JSON, XML, csv, tsv, etc.) (required)
  • Best used for structured data formats or when fast, direct access is needed

• get-rendered-html: Fetches fully rendered HTML content using a headless browser

  • Arguments:
    • url: URL of the target web page (required)
  • Essential for modern web applications and SPAs that require JavaScript rendering

• get-markdown: Converts web page content to well-formatted Markdown

  • Arguments:
    • url: URL of the target web page (required)
  • Preserves structural elements while providing clean, readable text output

• get-markdown-from-media: Performs AI-powered content extraction from media files

  • Arguments:
    • url: URL of the target media file (images, videos) (required)
  • Utilizes computer vision and OCR for visual content analysis
  • Requires a valid OPENAI_API_KEY to be set in environment variables
  • Will return an error message if the API key is not set or if there are issues processing the media file

Usage

Claude Desktop

To use with Claude Desktop, add the server configuration:

On MacOS: ~/Library/Application\ Support/Claude/claude_desktop_config.json
On Windows: %APPDATA%/Claude/claude_desktop_config.json

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

Environment Variables

The following environment variables can be configured:

• OPENAI_API_KEY: Required for using the get-markdown-from-media tool. This key is needed for AI-powered image analysis and content extraction.
• PYTHONIOENCODING: Set to "utf-8" if you encounter character encoding issues in the output.
• MODEL_NAME: Specifies the model name to use. Defaults to "gpt-4o".

"mcpServers": {
  "mcp-server-fetch-python": {
    "command": "uvx",
    "args": [
      "mcp-server-fetch-python"
    ],
    "env": {
        "OPENAI_API_KEY": "sk-****",
        "PYTHONIOENCODING": "utf-8",
        "MODEL_NAME": "gpt-4o",        
    }
  }
}

Local Installation

Alternatively, you can install and run the server locally:

git clone https://github.com/tatn/mcp-server-fetch-python.git
cd mcp-server-fetch-python
uv sync
uv build

Then add the following configuration to Claude Desktop config file:

"mcpServers": {
  "mcp-server-fetch-python": {
    "command": "uv",
    "args": [
      "--directory",
      "path\\to\\mcp-server-fetch-python",  # Replace with actual path to the cloned repository
      "run",
      "mcp-server-fetch-python"
    ]
  }
}
