Overview

What is SearXNG MCP Server?

A Model Context Protocol (MCP) server that enables AI assistants to perform web searches using SearXNG, a privacy-respecting metasearch engine. It works out‑of‑the‑box by automatically selecting a random public instance from SearX.space, and also supports private instances with basic authentication.

How to use SearXNG MCP Server?

Install from source with Node.js v16+ and npm v7+, then run node build/index.js. Configure via environment variables (SEARXNG_URL, SEARXNG_USERNAME, SEARXNG_PASSWORD, USE_RANDOM_INSTANCE) in a .env file or in the MCP server configuration for Claude Desktop or VSCode. Invoke the searxngsearch tool with a query parameter and optional parameters (language, time_range, categories, engines, safesearch, pageno, max_results).

Key features of SearXNG MCP Server

  • Zero-configuration setup using random public instances.
  • Support for private SearXNG instances with basic authentication.
  • Customizable search parameters (language, time range, categories, engines, safesearch).
  • Markdown‑formatted search results.
  • Sensible default values for all parameters.
  • Integration with Claude Desktop, VSCode, and Smolagents.

Use cases of SearXNG MCP Server

  • AI assistants performing privacy‑focused web searches.
  • Integrating web search into agentic workflows (e.g., with Smolagents).
  • Using a self‑hosted SearXNG instance for controlled search environments.
  • Obtaining search results in markdown for easy consumption by language models.

Frequently asked questions

1

What is the difference between this server and searxNcrawl?

This project is deprecated and its successor is `searxNcrawl` at https://github.com/DasDigitaleMomentum/searxNcrawl. The successor currently does not include round‑robin instance selection.

2

What are the runtime dependencies?

Node.js v16 or higher and npm v7 or higher are required. Access to a SearXNG instance (self‑hosted or public) is also needed.

3

Where does the search data come from?

By default, a random public SearXNG instance from SearX.space is used. You can also provide a custom instance URL via the `SEARXNG_URL` environment variable.

4

Are there any known limitations?

Public instances might be unavailable for this purpose and return "Request failed with status code 429". The successor `searxNcrawl` does not include round‑robin instance selection.

5

How is authentication handled?

Private instances can be accessed with basic authentication by setting `SEARXNG_USERNAME` and `SEARXNG_PASSWORD` environment variables.
