Quick Start

You need an existing SearXNG instance with JSON search enabled. This project connects an MCP client to SearXNG; it does not install SearXNG. Use an instance you operate or trust. Start with the self-hosted or public-instance guide if needed.

Choose how to connect:

Your setup	Start here
Client starts the server locally	Install Node.js 22 or later, then use the NPX example below or your client recipe.
Client starts a Docker container	Use the Docker/STDIO recipe in Installation.
You have an independently running HTTP service	Use your client's HTTP recipe with the full /mcp URL.
You need to operate an HTTP service	Follow the HTTP server guide.

For clients using mcpServers JSON (such as Claude Desktop), add:

{
  "mcpServers": {
    "searxng": {
      "command": "npx",
      "args": ["-y", "mcp-searxng"],
      "env": { "SEARXNG_URL": "https://search.example.com" }
    }
  }
}

Replace the example URL with your SearXNG base URL. Other clients use different configuration shapes: choose your client recipe. Leave MCP_HTTP_PORT unset for local STDIO. Docker also needs environment forwarding into the container.

Reload the client, inspect its MCP tool inventory, then ask it to search for SearXNG documentation. A simple tool call is searxng_web_search with {"query":"SearXNG"}. Discovery alone does not test SearXNG connectivity. If the call fails, start with troubleshooting.

Features

• Search with pagination, filters, direct answers and full or compact text/JSON output.
• Read HTML, structured text and bounded PDF text; inspect headings or selected sections.
• Discover instance capabilities and get query suggestions.
• Optional replica failover/fan-out, HTML fallback, caching, proxies and browser solvers.
• Local STDIO or Streamable HTTP, with static bearer and optional OAuth protection.

See the tool guide for capabilities and limits, configuration reference for settings, and historical deployment measurements for bounded resource-planning evidence.

Why mcp-searxng?

<details> <summary>Capability comparison recorded on 2026-07-29</summary>

As of 2026-07-29, the capability comparison below reflects the official Brave MCP, Exa MCP, and Firecrawl MCP projects. “Pagination” means an exposed page or offset control. “Self-hosted” means the search service can run under your control. “Free / No API key” means this MCP server does not require a paid search-vendor API key; you still operate or select the underlying SearXNG instance.

Privacy depends on the SearXNG deployment. An operator-controlled instance can avoid trusting a third-party search operator, while a public instance receives the query and may log it. SearXNG and this MCP integration do not by themselves provide anonymity.
