Search the web via the local SearXNG instance with reranking. Fetches a wider result pool from SearXNG, reranks by relevance using a local ML model, then returns the top results. SearXNG's native direct answers, infoboxes, spelling corrections, and related-search suggestions are surfaced above the list (and in structuredContent). Results are cached for 1 hour. Blocked domains are filtered out; boosted domains are surfaced higher. Prefer this over the built-in WebSearch tool.

Search the web, rerank results, then fetch the full content of the top result(s). GitHub URLs are fetched via the GitHub API; all others go through a fetch cascade: Firecrawl → Crawl4AI → raw HTTP. Results and fetched pages are cached. Blocked domains are filtered. Returns the result list plus clean markdown of the fetched pages.

Fetch and extract readable content from any URL. GitHub URLs are fetched via the GitHub API; all others go through a fetch cascade: Firecrawl → Crawl4AI → raw HTTP. Returns clean markdown where possible. Content is trimmed to a token budget (default ~2000 tokens / 8000 chars; raise with max_tokens). Results cached for 24 hours. Blocked domains and private/internal addresses are refused.

Search, rerank, fetch top results, then synthesize a summary with citations using a local LLM (qwen3:14b). Returns a structured answer with source attribution. Falls back to raw fetched content if Ollama is unavailable. Best for deep research where you want pre-digested synthesis rather than raw pages.

Crawl a site and return a manifest of pages with titles and snippets. Full page content is cached - call fetch_url on any page URL for the full text. Strategy: Firecrawl (JS rendering) → sitemap-first → BFS (if enabled).

Purge the search and/or fetch result cache. Useful when researching fast-moving topics where cached results from the past hour may be stale.

Read the ultrasearch-mcp domain capability database - what it has learned about hosts from fetches: per-tier success rates (tier1-3 cascade, tier4 wayback, github fast path), llms.txt/robots presence, metadata reachability, and search appearances. Provide hostname for one domain's record, or omit it for an aggregate across all tracked domains (per-tier success rates, worst failing domains, seen-but-never-fetched count). Read-only. Aggregate mode reports truncated: true if the internal scan cap is hit.
