# searxNcrawl, an open-source alternative to Tavily, Exa and Brave Search By Das Digitale Momentum, published 2026-11-03 Tavily, Exa and Brave Search give AI agents web search as a hosted API. searxNcrawl does the same job on your own hardware: an open-source MCP server that searches through your SearXNG instance and, opt-in, You.com, and crawls the results to Markdown. ## searxNcrawl, Tavily, Exa and Brave Search compared | Capability | searxNcrawl | Tavily | Exa | Brave Search | | --- | --- | --- | --- | --- | | Runs on | Your machine | Tavily's service | Exa's service | Brave's service | | Self-hosted search | Yes, MIT licence | No | No | No | | API key | None with your own SearXNG instance | Required | Optional; the hosted MCP endpoint is rate-limited without one | Required | | MCP server | Built in, STDIO or HTTP | `tavily-mcp`, local or hosted | `exa-mcp-server`, hosted at mcp.exa.ai | `@brave/brave-search-mcp-server` | | Search tool | `search` | `tavily-search` | `web_search_exa` | `brave_web_search` | | Read a page as Markdown | `crawl`, or `include_content=true` on `search` | `tavily-extract` | `web_fetch_exa` | No tool that reads a given URL | | Whole-site crawl | `crawl_site` with depth and page limits | Map and crawl tools | Not among its default tools | Not among its tools | | Where queries go | Your SearXNG instance; You.com only with your key | Tavily | Exa | Brave | | Licence of the MCP server | MIT | MIT | MIT | MIT | Provider facts as published in the READMEs of the official MCP servers of [Tavily](https://github.com/tavily-ai/tavily-mcp), [Exa](https://github.com/exa-labs/exa-mcp-server) and [Brave Search](https://github.com/brave/brave-search-mcp-server), fact-checked on 2026-11-03. searxNcrawl facts describe version 0.33.1. ## How the approaches differ Tavily, Exa and Brave Search are hosted search APIs built for software: you send a query, the provider searches its own systems and returns ranked results, and each request counts against your plan or a rate limit. Their official MCP servers are thin, MIT-licensed clients of those APIs; the search itself always runs at the provider. Exa stands out in one respect: its hosted MCP endpoint answers without a key, at lower limits, which makes it easy to try. searxNcrawl moves the search into your infrastructure. [SearXNG](https://docs.searxng.org/), a metasearch engine you run, forwards each query to the search engines you enable and merges their answers; searxNcrawl adds the MCP tools, the optional You.com provider and the crawler that turns result pages into Markdown. There is no account and no metering, and running SearXNG and a browser is your job. For an agent, the difference shows in three places: who holds the key, where the queries go, and who fixes it when search stops working. ## Reading pages, not only snippets Search snippets rarely hold the answer. Tavily and Exa offer tools that return the content of a page, and Brave lists a summarizer and an LLM context tool among its tools; searxNcrawl crawls the result pages itself, either in the same call with `include_content=true` or afterwards with `crawl`. Because it renders pages in Chromium, it also reads pages that build their content with JavaScript, and it removes repeated blocks such as navigation from the Markdown. For long pages, `crawl` can drop all links with `remove_links`, which shortens the Markdown further and leaves more of the context for the text. ## Privacy and data flow With a hosted API, every query and every page you ask for goes to the provider, together with your API key. With searxNcrawl, queries go to your SearXNG instance, which passes them on to the engines it is configured for on its own behalf; the engines see the address of your instance, not who asked. Queries reach You.com only if you add a You.com key, and those are processed in the US. Crawls fetch pages directly from your network. Search queries often contain names of customers, projects or internal systems. A self-hosted path does not tie them to an account: the upstream engines still receive the query text, but not who sent it. Crawled pages follow the same rule: the sites see a visit from your network, as they would from a browser in it. ## Result quality and coverage The results of SearXNG depend on the engines you enable and on how those engines treat your instance. When we tested a fresh instance on 2026-11-04, two default engines rate-limited or challenged it within the first queries, and the remaining engines still returned 20 results. Hosted providers avoid that problem, and some add capabilities of their own, such as Exa's agent tool or Brave's local, image and news search. Adding You.com as a second provider in searxNcrawl gives you a commercial index as a fallback without giving up the self-hosted default. Setup takes a little longer than with a hosted API: start SearXNG in a container, enable JSON output as described in the [SearXNG JSON API guide](https://www.searxncrawl.io/searxng-json-api/), then run `uvx searxncrawl setup`. After that there is no key to renew and no quota to watch, which also suits evaluation runs and CI jobs that search a lot. To steer the results, choose the engines in `settings.yml`, or per call with the `categories` and `engines` parameters that `search` passes to SearXNG. Our test used the default engines of SearXNG without any tuning. ## When searxNcrawl fits - You want web search for agents without an API key or usage fees: with your own SearXNG instance, searxNcrawl needs neither. - Search queries should stay on infrastructure you run. - Your agents need search, page content and whole-site crawls from one MCP server. - You want to combine sources: SearXNG and You.com, queried in parallel, merged and attributed per provider. It also suits teams that want one tool across their clients: the same server works in Claude Code, Codex, Gemini CLI, Cursor, VS Code and Claude Desktop, registered once with `uvx searxncrawl setup`. ## When a hosted search API fits better - You want no infrastructure at all: no SearXNG instance and no browser to run. - You need a feature of one provider, such as Exa's agent tool, Brave's local, image, video and news search, or Tavily's map and crawl. - The search engines behind your SearXNG instance rate-limit or block it. searxNcrawl Cloud is planned for these cases: a hosted MCP endpoint and premium search across several sources are among its [planned capabilities](https://www.searxncrawl.io/#cloud). None of them is available yet. You can also keep both registered: searxNcrawl as the default for search and reading pages, and one hosted provider for the cases above. Name the tools in your agent instructions so the agent knows which one to prefer. ## Which one to try first Start with searxNcrawl if you already run containers and want search without accounts: one SearXNG container and one setup command, and every MCP client on the machine can search and read pages. Start with a hosted provider if you need results within minutes on a machine where you cannot run containers, or a capability only that provider has. The keyless Exa endpoint is the quickest hosted trial; Tavily and Brave Search need an account and a key first. ## Switch an MCP client to searxNcrawl Run `uvx searxncrawl setup` to register searxNcrawl with Claude Code, Codex, Gemini CLI, Cursor, VS Code and Claude Desktop; the [SearXNG MCP server page](https://www.searxncrawl.io/searxng-mcp-server/) has the command for each client. The tools map like this: | Tavily, Exa or Brave Search tool | searxNcrawl MCP tool | | --- | --- | | `tavily-search`, `web_search_exa`, `brave_web_search` | `search` | | `tavily-extract`, `web_fetch_exa` | `crawl` | | Tavily's crawl tool | `crawl_site` | Tavily, Exa and Brave are trademarks of their owners; searxNcrawl is not affiliated with them.

Yes. searxNcrawl is MIT licensed and runs on your own hardware. With your own SearXNG instance it searches without an API key, and with `include_content=true` it returns the Markdown of each result page in the same call. ### Do I need an API key for web search in an MCP client? Not with searxNcrawl and your own SearXNG instance. The Tavily and Brave Search MCP servers need an API key; the hosted Exa MCP endpoint answers without one, at lower rate limits. ### Is searxNcrawl a drop-in replacement for the Tavily API? No. searxNcrawl has no Tavily-compatible REST API. Agents use it through its MCP tools, and scripts through its CLI or Python API. ### Where do my search queries go with searxNcrawl? To your own SearXNG instance, which forwards them to the search engines it is configured for. They go to You.com only if you add a You.com API key; those queries are processed in the US.
