Web Search & Data API MCP Server

Web search results (SERP). Keyless web search returning ranked title, URL, and snippet for a query — with locale/region targeting, freshness filters (past day, week, month, year), pagination, a news mode that adds publish date and source, and selectable backend engine (auto rotation, or pin Brave, Yahoo, or Yandex). [$0.05/call]. Params — q: search query; num_results: max results, cap 25; region: locale, e.g. us-en, uk-en, de-de; timelimit: restrict to past day/week/month/year (d|w|m|y); safesearch: string (on|moderate|off); page: result page (pagination); mode: web results or recent news (news adds date+source per item). the news index is narrow, so a long or highly specific news query that matches nothing falls through to web rather than returning empty; those items carry requestedMode=news and servedBy=web (web|news); engine: search backend: auto (recommended - rotates engines and falls back on blocks) or pin one of yahoo, yandex (web mode); news mode supports bing. when set, each result carries an 'engine' field; if the pinned engine returns nothing, auto serves instead and results also carry 'requestedEngine' Example params: {'q': 'best python web scraping library', 'num_results': 10}

Bulk web search: up to 5 search queries in a single call, each returning ranked title, URL, and snippet, with the same locale, freshness, and news filters as the single-query web search. One paid call instead of five for research fan-out. [$0.10/call]. Params — queries: up to 5 search queries separated by '|'; num_results: max results per query, cap 25; region: locale, e.g. us-en, uk-en, de-de; timelimit: restrict to past day/week/month/year (d|w|m|y); safesearch: string (on|moderate|off); mode: string (web|news); engine: search backend: auto (recommended) or yahoo/yandex (web); bing (news) Example params: {'queries': 'python asyncio tutorial|rust tokio tutorial'}

Multi-engine web search (metasearch). One search query fanned out across 2-3 search engines (Brave, Yahoo, Yandex) with results deduplicated by URL and merged by reciprocal-rank fusion: consensus ranking across engines instead of one engine's bias, with per-engine rank attribution on every result. [$0.05/call]. Params — q: search query; engines: comma list of 2-3 engines: yahoo, yandex (web mode). news mode has a single live engine (bing), so multi-engine is web-only; num_results: max results per engine, cap 25; region: locale, e.g. us-en, uk-en, de-de; timelimit: restrict to past day/week/month/year (d|w|m|y); safesearch: string (on|moderate|off); mode: string (web|news) Example params: {'q': 'best vector database 2026', 'engines': 'yahoo,yandex'}

Params — q: search query; fetch_top: how many top results to fetch and extract, cap 5; maxChars: max markdown chars per fetched page; num_results: ranked results to return, cap 25; region: locale, e.g. us-en, uk-en, de-de; timelimit: restrict to past day/week/month/year (d|w|m|y); safesearch: string (on|moderate|off); mode: string (web|news); engine: search backend: auto (recommended) or yahoo/yandex (web); bing (news) Example params: {'q': 'how does x402 payment protocol work', 'fetch_top': 3}
