Frequently asked questions

1

How does mcp-searxng-public differ from other SearXNG MCP servers?

Most SearXNG MCP servers use the JSON output format, which fails on public servers. This server parses HTML from public instances and includes fallback servers for reliability.

2

What environment variables are required?

`SEARXNG_BASE_URL`: a semicolon-separated list of SearXNG URLs (default list provided). `DEFAULT_LANGUAGE`: language code (e.g., `en`). Optional, falls back to no language if unset.

3

Where does the search data come from?

Data comes from public SearXNG instances specified in the `SEARXNG_BASE_URL` environment variable. The server reads up to three of these, using the first as primary and others as fallback.

4

What transport or authentication does the server use?

The server communicates via the Standard Input/Output (stdio) transport. No authentication is configured; it relies on public SearXNG instances.

5

Are there any known limitations?

The server relies on publicly accessible SearXNG instances, which may have rate limits or become unavailable. It parses HTML, so result structure may change if instance UI updates.
