SearXNG Model Context Protocol Server

A Model Context Protocol (MCP) server for interfacing language models with SearXNG search engine.

Description

This server enables language models to perform web searches through SearXNG using the Model Context Protocol standard. It provides a clean interface for language models to send search queries to SearXNG and receive formatted results.

Installation

# Clone the repository
git clone https://github.com/aeon-seraph/searxng-mcp.git
cd searxng-mcp

# Install dependencies
npm install

# Build the project
npm run build

Requirements

• Node.js 16+
• A running SearXNG instance (by default at http://localhost:8888)

Usage

# Run the server
node build/index.js

The server will run on stdio, making it suitable for integration with MCP-compatible language models.

Configuration

The server can be configured using environment variables:

Variable	Description	Default
SEARXNG_PROTOCOL	Protocol to use (http/https)	http
SEARXNG_HOST	SearXNG host	localhost
SEARXNG_PORT	SearXNG port	8888
CACHE_TTL	Cache time-to-live in milliseconds	600000 (10 minutes)
MAX_CACHE_SIZE	Maximum number of cached queries	100

Example:

SEARXNG_HOST=mysearx.example.com SEARXNG_PORT=443 SEARXNG_PROTOCOL=https node build/index.js

Docker

The project includes a Dockerfile for easy deployment:

# Build the Docker image
docker build -t searxng-mcp .

# Run the container
docker run -e SEARXNG_HOST=mysearx.example.com -e SEARXNG_PROTOCOL=https searxng-mcp

Search Parameters

The search function supports the following parameters:

• query (required): The search query string
• categories: Comma-separated list of search categories
• pageno: Search page number (default: 1)
• time_range: Time range for results ("day", "week", "month", "year")
• raw_json: Return raw JSON response instead of formatted text (default: false)
