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
