Prysm MCP Server

The Prysm MCP (Model Context Protocol) Server enables AI assistants like Claude and others to scrape web content with high accuracy and flexibility.

Features

• Multiple Scraping Modes: Choose from focused (speed), balanced (default), or deep (thorough) modes
• Content Analysis: Analyze URLs to determine the best scraping approach
• Format Flexibility: Format results as markdown, HTML, or JSON
• Image Support: Optionally extract and even download images
• Smart Scrolling: Configure scroll behavior for single-page applications
• Responsive: Adapts to different website layouts and structures
• File Output: Save formatted results to your preferred directory

Usage

There are multiple ways to set up Prysm MCP Server:

Using mcp.json Configuration

Create a mcp.json file in the appropriate location according to the above guides.

{
  "mcpServers": {
    "prysm-scraper": {
      "description": "Prysm web scraper with custom output directories",
      "command": "npx",
      "args": [
        "-y",
        "@pinkpixel/prysm-mcp"
      ],
      "env": {
        "PRYSM_OUTPUT_DIR": "${workspaceFolder}/scrape_results",
        "PRYSM_IMAGE_OUTPUT_DIR": "${workspaceFolder}/scrape_results/images"
      }
    }
  }
}

Tools

The server provides the following tools:

scrapeFocused

Fast web scraping optimized for speed (fewer scrolls, main content only).

Please scrape https://example.com using the focused mode

Available Parameters:

• url (required): URL to scrape
• maxScrolls (optional): Maximum number of scroll attempts (default: 5)
• scrollDelay (optional): Delay between scrolls in ms (default: 1000)
• scrapeImages (optional): Whether to include images in results
• downloadImages (optional): Whether to download images locally
• maxImages (optional): Maximum images to extract
• output (optional): Output directory for downloaded images

scrapeBalanced

Balanced web scraping approach with good coverage and reasonable speed.

Please scrape https://example.com using the balanced mode

Available Parameters:

• Same as scrapeFocused with different defaults
• maxScrolls default: 10
• scrollDelay default: 2000
• Adds timeout parameter to limit total scraping time (default: 30000ms)

scrapeDeep

Maximum extraction web scraping (slower but thorough).

Please scrape https://example.com using the deep mode with maximum scrolls

Available Parameters:

• Same as scrapeFocused with different defaults
• maxScrolls default: 20
• scrollDelay default: 3000
• maxImages default: 100

formatResult

Format scraped data into different structured formats (markdown, HTML, JSON).

Format the scraped data as markdown

Available Parameters:

• data (required): The scraped data to format
• format (required): Output format - “markdown”, “html”, or “json”
• includeImages (optional): Whether to include images in output (default: true)
• output (optional): File path to save the formatted result

You can also save formatted results to a file by specifying an output path:

Format the scraped data as markdown and save it to "my-results/output.md"

Configuration

Output Directory

By default, when saving formatted results, files will be saved to ~/prysm-mcp/output/. You can customize this in two ways:

1. Environment Variables: Set environment variables to your preferred directories:

# Linux/macOS
export PRYSM_OUTPUT_DIR="/path/to/custom/directory"
export PRYSM_IMAGE_OUTPUT_DIR="/path/to/custom/image/directory"

# Windows (Command Prompt)
set PRYSM_OUTPUT_DIR=C:pathtocustomdirectory
set PRYSM_IMAGE_OUTPUT_DIR=C:pathtocustomimagedirectory

# Windows (PowerShell)
$env:PRYSM_OUTPUT_DIR="C:pathtocustomdirectory"
$env:PRYSM_IMAGE_OUTPUT_DIR="C:pathtocustomimagedirectory"

2. Tool Parameter: Specify output paths directly when calling the tools:

# For general results
Format the scraped data as markdown and save it to "/absolute/path/to/file.md"

# For image downloads when scraping
Please scrape https://example.com and download images to "/absolute/path/to/images"

3. MCP Configuration: In your MCP configuration file (e.g., .cursor/mcp.json), you can set these environment variables:

{
  "mcpServers": {
    "prysm-scraper": {
      "command": "npx",
      "args": ["-y", "@pinkpixel/prysm-mcp"],
      "env": {
        "PRYSM_OUTPUT_DIR": "${workspaceFolder}/scrape_results",
        "PRYSM_IMAGE_OUTPUT_DIR": "${workspaceFolder}/scrape_results/images"
      }
    }
  }
}

If PRYSM_IMAGE_OUTPUT_DIR is not specified, it will default to a subfolder named images inside the PRYSM_OUTPUT_DIR.

If you provide only a relative path or filename, it will be saved relative to the configured output directory.

Path Handling Rules

The formatResult tool handles paths in the following ways:

• Absolute paths: Used exactly as provided (/home/user/file.md)
• Relative paths: Saved relative to the configured output directory (subfolder/file.md)
• Filename only: Saved in the configured output directory (output.md)
• Directory path: If the path points to a directory, a filename is auto-generated based on content and timestamp

Development

# Install dependencies
npm install

# Build the project
npm run build

# Run the server locally
node bin/prysm-mcp

# Debug MCP communication
DEBUG=mcp:* node bin/prysm-mcp

# Set custom output directories
PRYSM_OUTPUT_DIR=./my-output PRYSM_IMAGE_OUTPUT_DIR=./my-output/images node bin/prysm-mcp

Running via npx

You can run the server directly with npx without installing:

# Run with default settings
npx @pinkpixel/prysm-mcp

# Run with custom output directories
PRYSM_OUTPUT_DIR=./my-output PRYSM_IMAGE_OUTPUT_DIR=./my-output/images npx @pinkpixel/prysm-mcp
