SearxNG MCP Server

A Model Context Protocol (MCP) server that provides search capabilities through SearxNG, the privacy-respecting metasearch engine.

PyPi: https://pypi.org/project/searxng-mcp-server/#description

Usage

Using uvx

You can also just pip install this but we recommend using uv.

# With command line argument (stdio transport)
uvx searxng-mcp-server --searxng-url https://searx.be

# With environment variable (stdio transport)
SEARXNG_URL=https://searx.be uvx searxng-mcp-server

# With HTTP transport on port 8080
uvx searxng-mcp-server --searxng-url https://searx.be --port 8080

# With HTTP transport using environment variable
SEARXNG_URL=https://searx.be MCP_PORT=8080 uvx searxng-mcp-server

Package link: https://pypi.org/project/searxng-mcp-server/

Using Docker/Podman

# With command line argument (stdio transport)
podman run --rm -i docker.io/icewreck/searxng-mcp-server:latest --searxng-url https://searx.be

# With environment variable (stdio transport)
podman run --rm -i -e SEARXNG_URL=https://searx.be docker.io/icewreck/searxng-mcp-server:latest

# With HTTP transport on port 8080
podman run --rm -i -e SEARXNG_URL=https://searx.be -p 8080:8080 docker.io/icewreck/searxng-mcp-server:latest --port 8080

Usage as Library

You can also use the SearxNG client directly in your Python projects. The client is fully async and requires async/await syntax.

For detailed examples, see the examples/client_example.py file in the repository.

The SearxNGClient can be easily integrated into custom AI agents as a search tool. All search methods are async and return structured response objects.

Available Tools

• search_web: General web search with language and time filtering

• search_images: Image search across multiple search engines

• search_videos: Video search from various platforms

• search_news: News search with time range filtering

• fetch_url: Fetch content from a URL and convert it to markdown

Configuration

The server requires a SearxNG instance URL. You can provide it via:

• Environment Variable: SEARXNG_URL=https://your-searxng-instance.com

• Command Line Argument: --searxng-url https://your-searxng-instance.com

By default, the server uses stdio transport. To enable HTTP transport, set a port:

• Environment Variable: MCP_PORT=8080

• Command Line Argument: --port 8080

When a port is provided, the server listens on http://0.0.0.0:<port> using the streamable-http transport.

Optional: SEARXNG_TIMEOUT (default: 30), SEARXNG_USER_AGENT, LOG_LEVEL
