clear_cache
Purge the search cache, fetch cache, crawl manifest cache, or all. Useful when researching fast-moving topics where cached results may be stale.
How to use it
Project documentation lists clear_cache for the Searxng MCP MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.
Install Searxng MCP

Crawl an entire site and return a manifest of URL/title/snippet for each page. Tries Firecrawl crawl first, falls back to sitemap parsing, then optional BFS. Full page content is cached in Valkey so follow-up fetchurl calls are zero-cost.
Read-only view of the domain capability database. With hostname: one domain's per-tier success rates and capability flags. Without: an aggregate across all tracked domains (per-tier success, worst failing domains, seen-but-never-fetched count). Returns MCP structured output (structuredContent) for p
Fetch and extract readable markdown from any public URL. GitHub hosts take the GitHub fast path; YouTube video URLs return the transcript and Reddit thread URLs return post+comments (both opt-in via robots, see below); all others use the fetch cascade (Firecrawl → Crawl4AI → raw HTTP). Trimmed to a
Search via SearXNG with local reranking. Fetches a wider result pool, reranks by relevance, returns top N. SearXNG's native direct answers, infoboxes, spelling corrections, and related suggestions are surfaced above the list and in structuredContent.
Search, rerank, then fetch full content of the top result(s) using the fetch cascade (Firecrawl → Crawl4AI → raw HTTP).
Search, fetch top results, then synthesize a summary with citations via Ollama (OLLAMASUMMARIZEMODEL). Falls back to raw fetched content if Ollama is unavailable.
