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

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
