MCP Server Search

June 11, 2025 ยท View on GitHub

An MCP (Model Context Protocol) server that provides Google search functionality for AI models. This server allows models to search for up-to-date information from the web.

Features

  • Google search integration with caching
  • Configurable request delays and retries to avoid rate limiting
  • Support for both simple and advanced searches (with descriptions)
  • Throttling and randomization to be a good web citizen

Installation

  1. Build the Docker image:

    docker build -t mcp-server-search .
    
  2. Create required directories for persistence:

    mkdir -p ./logs ./cache
    
  3. Run the container (with SSE enabled):

    docker run --rm -p 8000:8000 \
      -v "$(pwd)/logs:/app/logs" \
      -v "$(pwd)/cache:/app/cache" \
      mcp-server-search
    

This will start the server with SSE enabled and make it accessible at http://localhost:8000/sse.

The volumes ensure:

  • Logs are persisted to ./logs directory
  • Search cache is persisted to ./cache directory
  • Both directories are automatically created by Docker if they don't exist

Note: The -i flag is required for MCP protocol communication, and --rm automatically removes the container when it exits.

Cline Integration

To use this MCP server with Cline, add the following configuration to your Cline MCP settings file (located at ~/.config/Code/User/globalStorage/rooveterinaryinc.roo-cline/settings/cline_mcp_settings.json for VS Code):

{
    "mcpServers": {
        "google_search": {
            "url": "http://localhost:8000/sse"
        }
    }
}

This configuration:

  • Connects to the search MCP server via HTTP SSE on port 8000 at the /sse endpoint
  • No longer uses the Docker stdio transport; Cline connects directly to the HTTP endpoint

Configuration

The server accepts the following command-line arguments:

  • --log-level: Set the logging level (DEBUG, INFO, WARNING, ERROR, CRITICAL). Default: INFO
  • --log-file: Path to log file (default: stdout)
  • --cache-path: Path to the search cache file (default: cache/google_cache.db)
  • --request-delay: Delay between search requests in seconds (default: 5)
  • --max-retries: Maximum number of retries for failed searches (default: 3)

Usage

The server exposes the following MCP endpoints:

Tools

  • google_search: Search Google and return results. Results are presented in a formatted Markdown structure with titles, URLs, and descriptions (when enabled).

    Parameters:

    • query (string, required): The search query to execute
    • num_results (integer, optional): Number of results to return (min: 1, max: 20, default: 5)
    • use_cache (boolean, optional): Whether to use cached results if available (default: true)
    • include_descriptions (boolean, optional): Whether to include descriptions in results (default: true)

    Features:

    • Automatic request throttling and retry mechanism
    • Random user agent rotation for better request distribution
    • File-based caching with thread-safe access
    • Exponential backoff on rate limiting (HTTP 429)

Prompts

  • google_search: Search Google with the given query. Returns results in a conversational format.

    Parameters:

    • query (string, required): The search query to execute
    • num_results (integer, optional): Number of results to return (1-20, default: 5)
