Can't enable JSON? (HTML fallback)

If you must use a public instance you don't control and it rejects format=json (the 403 above), set the opt‑in flag instead of editing the server: before enabling it, review the public operator's policy and the public‑instance usage guide. A search that gets a 403/404 or a non‑JSON response is then retried automatically without format=json and parsed from the regular HTML results page. On success you get normal results (title, URL, snippet) marked sourceFormat: "html" in JSON mode, and text mode adds the line "Note: Results parsed from SearXNG HTML fallback; metadata is limited." Relevance scores and engine names are not available from HTML. On failure, parsing is best‑effort and varies by the instance's theme/version, so some results may be missed or sparse. If the HTML page itself also fails — still blocked, rate‑limited (429), auth (401), or 5xx — the fallback attempt's error is surfaced, so the search never silently returns empty results. The fallback only triggers on 403/404/non‑JSON, never on auth or network errors. Enabling JSON on an instance you control remains the recommended setup — the fallback is a compatibility aid, not a replacement.

How It Works?

mcp-searxng is a standalone MCP server — a separate Node.js process that your AI assistant connects to for web search. It queries one SearXNG instance, or a semicolon‑separated list of interchangeable SearXNG replicas, via the HTTP JSON API. This project cannot be installed as a native SearXNG plugin. Point it at any existing SearXNG instance, or interchangeable replica list, by setting SEARXNG_URL. For SearXNG deployment, configuration, and troubleshooting, see Operating Self‑Hosted SearXNG with mcp-searxng.

Why mcp-searxng?

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. | | Brave MCP | Exa MCP | Firecrawl MCP | mcp-searxng | |--|:---------:|:-------:|:-------------:|:---------------:| | Web Search | ✓ | ✓ | ✓ | ✓ | | Read URL | ✗ | ✓ | ✓ | ✓ | | Pagination | ✓ | ✗ | ✓ | ✓ | | Self-hosted | ✗ | ✗ | Partial | ✓ | | Free / No API key | ✗ | ✗ | ✗ | ✓ | 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.
