Tavily vs Brave Search
Tavily MCP and Brave Search MCP are both official, API-key-authenticated servers in the search-and-data category, but they cover the agent search loop in very different ways. Tavily exposes four tools: tavily-search for real-time LLM-optimized web search, tavily-extract for pulling clean content from specific pages, tavily-crawl for systematically following links across a domain, and tavily-map for generating a structured map of a site's pages. Brave Search exposes eight tools: brave_web_search, brave_local_search, brave_video_search, brave_image_search, brave_news_search, brave_summarizer, brave_place_search, and brave_llm_context, all drawing on Brave's independent search index. Tavily leans into depth (extract, crawl, map); Brave leans into breadth (six distinct media and result types).
How they compare
| Dimension | Tavily | Brave Search |
|---|---|---|
| Tool surface | Four tools covering search, page extraction, site crawling, and site mapping: tavily-search, tavily-extract, tavily-crawl, and tavily-map. | Eight tools covering web, local, video, image, news, place, AI summarization, and RAG-ready context: brave_web_search, brave_local_search, brave_video_search, brave_image_search, brave_news_search, brave_summarizer, brave_place_search, and brave_llm_context. |
| Going deep on a site vs. searching broadly | Beyond search, tavily-crawl follows links across a domain systematically and tavily-map returns a structured map of a site's pages, covering the fetch-and-traverse loop without a separate scraping server. | Stays in the search layer: brave_web_search, brave_news_search, and brave_llm_context return results from Brave's own index. There is no crawl or site-map tool to traverse a specific domain. |
| Media and result types | Results are text-focused: tavily-search and tavily-extract return clean text content. No image, video, news, or local business tools. | brave_image_search returns images as base64, brave_video_search returns video metadata, brave_news_search returns current articles with freshness controls, and brave_local_search and brave_place_search cover businesses and points of interest. |
| Index and summarization | Tavily runs its own search index tuned for LLM consumption and returns citation-ready results from tavily-search without a separate summarization step. | Brave runs an independent index that does not depend on a third-party engine, and brave_summarizer generates an AI summary from web results; brave_llm_context returns pre-extracted, RAG-friendly content for grounding pipelines. |
| Deployment and auth | Local stdio via npx with a TAVILY_API_KEY env var, plus a hosted remote endpoint at https://mcp.tavily.com/mcp/ that supports both an API key as a query parameter and OAuth for clients that handle it automatically. | Local stdio via npx with a BRAVE_API_KEY env var; an HTTP transport mode is available behind a flag. No hosted OAuth endpoint. |
Verdict
Pick Tavily MCP when the task involves reading and traversing a target site: tavily-extract, tavily-crawl, and tavily-map give an agent the tools to pull content, follow links, and map a domain without bolting on a separate scraper. Pick Brave Search MCP when the task requires breadth across result types: brave_image_search, brave_video_search, brave_news_search, brave_local_search, brave_place_search, and brave_llm_context cover media and local queries that Tavily does not expose. Both serve real-time general web search well; the divergence is crawl depth versus result-type breadth.
FAQ
- Which supports OAuth for remote access?
- Tavily does. Its hosted endpoint at https://mcp.tavily.com/mcp/ supports OAuth so compatible clients handle authorization automatically, and the API key can be passed as a query parameter for headless use. Brave Search runs over local stdio and offers an HTTP transport mode but does not expose an OAuth endpoint.
- Can either server crawl a website or map its pages?
- Only Tavily. tavily-crawl follows links systematically across a domain and tavily-map returns a structured map of a site's pages. Brave Search has no crawl or map tool; its tools all operate at the search-results layer.
