Web Search MCP Server

A Model Context Protocol (MCP) server that enables free web searching using Google search results, with no API keys required.

Features

npm install

npm run build

For VSCode (Claude Dev Extension):

{
  "mcpServers": {
    "web-search": {
      "command": "node",
      "args": ["/path/to/web-search/build/index.js"]
    }
  }
}

For Claude Desktop:

{
  "mcpServers": {
    "web-search": {
      "command": "node",
      "args": ["/path/to/web-search/build/index.js"]
    }
  }
}

The server provides a single tool named search that accepts the following parameters:

{
  "query": string,    // The search query
  "limit": number     // Optional: Number of results to return (default: 5, max: 10)
}

Example usage:

use_mcp_tool({
  server_name: "web-search",
  tool_name: "search",
  arguments: {
    query: "your search query",
    limit: 3  // optional
  }
})

Example response:

[
  {
    "title": "Example Search Result",
    "url": "https://example.com",
    "description": "Description of the search result..."
  }
]

Since this tool uses web scraping of Google search results, there are some important limitations to be aware of:

Rate Limiting: Google may temporarily block requests if too many searches are performed in a short time. To avoid this:
- Keep searches to a reasonable frequency
- Use the limit parameter judiciously
- Consider implementing delays between searches if needed
Result Accuracy:
- The tool relies on Google's HTML structure, which may change
- Some results might be missing descriptions or other metadata
- Complex search operators may not work as expected
Legal Considerations:
- This tool is intended for personal use
- Respect Google's terms of service
- Consider implementing appropriate rate limiting for your use case
