Prerequisites

• Python 3.8+

• A running SearXNG instance (default: http://localhost:8080)

Installation

1. Clone or download this repository

2. Install dependencies:

pip install -r requirements.txt

3. Ensure SearXNG is running locally at http://localhost:8080

Configuration

Edit searxng_mcp_server.py to customize:

SEARXNG_BASE_URL = "http://localhost:8080/search"  # Your SearXNG instance
DEFAULT_MAX_RESULTS = 5                            # Default search results
DEFAULT_MAX_WORDS = 5000                           # Max words per page
REQUEST_TIMEOUT = 20                               # Request timeout (seconds)
SERVER_PORT = 8765                                 # Server port
USE_TOR = False                                    # Route scraping through Tor (requires Tor on 127.0.0.1:9050)

Tor Support

To enable anonymous scraping through Tor:

1. Install and start Tor service (must be running on 127.0.0.1:9050)

2. Set USE_TOR = True in the configuration

3. Restart the server

When enabled, all web scraping requests will be routed through the Tor network.

Usage

Start the Server

python searxng_mcp_server.py

The server will run on http://localhost:8765

Configure with LM Studio

Add to your LM Studio MCP settings:

{
  "mcpServers": {
    "searxng": {
      "url": "http://localhost:8765",
      "transport": "http"
    }
  }
}

How It Works

1. Receives MCP tool calls from AI assistants

2. Queries SearXNG with specified search terms

3. Retrieves search results in JSON format

6. Truncates content to word limit

7. Returns formatted results to the AI assistant
