FAQ from SearxNG MCP Server

What SearxNG instance does the server use by default?

The default is the public instance at https://paulgo.io/.

What transport protocols are supported and how do I choose?

The server supports stdio (default for CLI and direct MCP integration) and sse (for HTTP‑based clients). Set the TRANSPORT_PROTOCOL environment variable to sse to use SSE.

What are the prerequisites to run the server?

Python 3.10 or higher and a SearxNG instance (public or self‑hosted) are required.

Can I use a custom SearxNG instance?

Yes, by setting the SEARXNG_MCP_SEARXNG_URL environment variable to your instance’s URL.

Do I need to install the package permanently?

No. You can run it on the fly with pipx run searxng-simple-mcp or uvx run searxng-simple-mcp, or via Docker without permanent installation.
