Overview

What is Searxng Mul Mcp?

Searxng Mul Mcp is a Model Context Protocol (MCP) server for integrating SearXNG, a metasearch engine, into MCP-compatible clients. It enables multi-query parallel search and supports both stdio and HTTP transport protocols. Designed for developers and AI assistants, it provides a single search tool to query SearXNG via its REST API without browser automation.

How to use Searxng Mul Mcp?

You can run it directly via npx (e.g., SEARXNG_URL=https://your.searxng.com npx -y searxng-mul-mcp) or deploy with Docker. Configure via environment variables: SEARXNG_URL (required), optional USERNAME/PASSWORD for Basic Auth, TRANSPORT, HOST, PORT. For HTTP mode, add --transport=http --host=0.0.0.0 --port=3000. Integrate with Claude Desktop by adding a mcpServers entry in claude_desktop_config.json. Install from source with npm install && npm run build && npm start.

Frequently asked questions

1

What do I need to run Searxng Mul Mcp?

A SearXNG instance URL is required. Node.js 18+ for source/npx usage, or Docker for containerized deployment. Optionally, Basic Auth credentials if your SearXNG server is protected.

2

How do I switch between stdio and HTTP transports?

Set `TRANSPORT=stdio` or `TRANSPORT=http` in environment variables, or use the `--transport` CLI flag. HTTP mode requires `HOST` and `PORT` (default 0.0.0.0:3000) and provides a `/health` endpoint and `/mcp` endpoint for clients.

3

How does authentication work?

If your SearXNG server uses Basic Auth, provide `USERNAME` and `PASSWORD` as environment variables. The server passes these credentials along with API requests.

4

What search parameters can I use?

The single `search` tool accepts required `queries` (array of strings), and optional `engines`, `categories`, `safesearch` (0–2), and `language` (e.g., "en", "zh").

5

How are errors handled?

Network errors retry up to 3 times. Authentication failures, API rate limits, and timeouts (default 30 seconds) produce clear error messages. Enable `DEBUG=true` for detailed logging.
