Skrapr - MCP Server

🎉 Cloud version available! Fill this form to get access.

Skrapr is an intelligent web scraping tool that combines AI capabilities with browser automation to extract structured data from websites.

In short:

website url + JSON schema = structured website data

This tool is an alternative between http request tool (dump) and scraper tools (brute force).

Example

Once configured, you can use Skrapr's capabilities directly in any MCP client (Claude Desktop, n8n, librechat, ...).

For example, you can ask Claude:

Extract product information from all categories at https://example.com/products.
I want name, description and price for each product.

The model with create a similar schema and pass it to Skrapr :

{
    "type":"object",
    "properties":{
        "products":{
            "type":"array",
            "items":{
                "type":"object",
                "properties":{
                    "name":{
                        "type":"string"
                    },
                    "price":{
                        "type":"string"
                    },
                    "description":{
                        "type":"string"
                    }
                }
            }
        }
    }
}

Scrapr will navigate the website, page by page, until it has found all the data it needs.

After scraping, you will receive the following response :

{
    "products": [
        {
            "name": "Product 1",
            "price": "10",
            "description": "Description of product 1"
        },
        {
            "name": "Product 2",
            "price": "20",
            "description": "Description of product 2"
        }
    ]
}

Getting Started with MCP Host

For a typical MCP Host integration (Claude Desktop), here's how to set it up:

With .NET:

{
  "mcpServers": {
    "skrapr": {
      "command": "dotnet",
      "args": [
        "run",
        "--project",
        "path/to/Skrapr/Skrapr.csproj"
        "-e", "AzureOpenAi__ApiKey=your-api-key", 
        "-e", "AzureOpenAi__Endpoint=https://your-resource.openai.azure.com/", 
        "-e", "AzureOpenAi__DeploymentName=your-deployment-name", 
        "-e", "PlaywrightMcp__IsLocal=true", 
      ]
    }
  }
}

With Docker:

1. Build the Docker image:

   docker build -t skrapr .
   

2. Run the container:

   docker run \
        -p 80:80 \
        -e AzureOpenAi__ApiKey=your-api-key \
        -e AzureOpenAi__Endpoint=https://your-resource.openai.azure.com/ \
        -e AzureOpenAi__DeploymentName=your-deployment-name \
        -e PlaywrightMcp__IsLocal=true \
        skrapr
   

3. The MCP server will be available at http://localhost:5000.

4. You can configure your MCP Host

   {
     "mcpServers": {
       "skrapr": {
         "url": "http://localhost:5000/sse"
       }
     }
   }
   

With Cloud version

I am hosting a Skrapr instance on Cloud with everything configured.

If you are interested to try it out, reach me here to get access to the beta.

    {
      "mcpServers": {
        "skrapr": {
          "url": "https://[ask-for-url]/sse"
        }
      }
    }

Playwright configuration

Playwright can be executed locally or remotely.

Local

Setting environment variable PlaywrightMcp__IsLocal=true will make Playwright run locally.

You need to have Node.js installed to make it work.

It uses npx @playwright/mcp to run Playwright.

Remote

Setting environment variable PlaywrightMcp__Endpoint will use Playwright on a remote host.

Under the hood?

AI Agent

Skrapr uses an AI agent internally aiming to :

• Understand website structure and content
• Autonomously navigate across the website
• Make strategic navigation decisions to locate the requested information
• Produce a structured JSON result based on a provided JSON schema.

Technical stack

It uses:

• Microsoft's Semantic Kernel to build the agent
• Playwright MCP to expose tools for websites navigation
• Azure OpenAI for AI capabilities and data extraction according to user-defined JSON schemas

Thanks to MCP (Model Context Protocol), you can connect Skrapr to any agent whatever the language.

Why Skrapr?

When building a AI Agent, you may want the agent to extract easily information from websites.

Currently, ai models can't navigate websites natively.

Simple HTTP Request tools exist however there is few limitations :

• No javascript execution: cannot read dynamic content
• Information may not be present in the loaded page, but in a subpage

Scraper tools are also exists, but they :

• Load to much information (randomly scrape)
• Takes to much time to scrape
