Web search via SearXNG and/or You.com, plus clean Markdown crawling via Crawl4AI. Self-hosted.

概览

AI 生成的概览

自托管的 MCP 服务器,让助手通过 SearXNG 和/或 You.com 进行网页搜索,并把网页与整站抓取为干净的 Markdown。

可以做什么
  • 并行调用已配置的搜索提供方检索网页,合并去重并标注每条结果的来源,可按语言、时间范围、安全搜索和分页筛选
  • 用 Chromium 渲染一个或多个网址,返回带元数据和引用的 Markdown 或 JSON
  • 从种子网址按深度、页数和超时限制抓取整站,针对文档站点优化
  • 借助已保存的浏览器会话状态抓取需要登录的页面
  • 同时提供命令行工具和 Python API
适用场景
适合希望助手获取最新网页结果和可读正文、又不想为托管搜索或抓取 API 付费的场景,例如查文档、总结文章或收集站点页面。适合已经运行或愿意自建 SearXNG 实例,或持有 You.com 密钥的用户。
运行要求
通过 uvx 以 STDIO 在本地运行,需要 uv。搜索至少需要一个提供方:启用 JSON 输出的 SearXNG 实例(通过 SEARXNG_URL 配置)和/或 YDC_API_KEY 中的 You.com 密钥;抓取无需任何搜索提供方。首次抓取会下载 Playwright 的 Chromium(约 550 MB)。可选基本认证使用 SEARXNG_USERNAME 与 SEARXNG_PASSWORD;SEARXNG_EXTRA_HEADERS 可添加自定义请求头。
安装前请注意
使用 You.com 时查询内容会发送到位于美国的 You.com,搜索词会离开本机。SEARXNG_PASSWORD、SEARXNG_EXTRA_HEADERS 和 YDC_API_KEY 属于机密,请求头值可从密钥文件读取。抓取会访问任意网址并可携带已保存的登录会话,会话状态文件应妥善保护。可选的 HTTP 传输默认不认证,需置于带认证的 TLS 代理之后并启用 Host/Origin 校验。

安装

在 SourceWeft 中

  1. 打开 控制台中的 searxNcrawl,将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Desktop only,通过 STDIO。 STDIO 服务会启动本地进程,因此需要 SourceWeft 桌面宿主。

[An MCP client starts uvx searxncrawl, calls search for crawl4ai quick start, then crawls the top result and receives clean Markdown]
A real MCP client session (fastmcp) against uvx searxncrawl 0.31.0 and a local SearXNG: search, then crawl the top hit into Markdown. Output is shortened for display. Reproduce it with docs/assets/demo/.

searxNcrawl is an open-source MCP server and CLI toolkit that gives AI agents web search and clean Markdown crawling, built on Crawl4AI. Search queries the configured providers, SearXNG and/or You.com, in parallel and merges the results. It runs on your own hardware, needs no API key with SearXNG and succeeds searxng-mcp.

Web search
Your own SearXNG instance and/or the You.com API, queried in parallel; results are merged and attributed to their providers, filtered by language and time range.
Page crawl
One or many URLs to Markdown or JSON, with repeated blocks removed and links optionally stripped.
Site crawl
Whole sites with depth and page limits, tuned for documentation.
Authenticated crawls
Capture a login session once with crawl-capture, then crawl behind the login.
STDIO and HTTP
Plug into local MCP clients, or run an HTTP endpoint with opt-in Host/Origin checks and configurable CORS.
CLI and Python API
crawl, search and crawl-capture on the command line, or import it in Python.
bash
SEARXNG_URL=http://your-searxng:8888 uvx searxncrawl

Quick start

Connect your MCP client directly to searxNcrawl over STDIO or its HTTP endpoint.

You need uv and, for the search tool, at least one search provider: a SearXNG instance with JSON output enabled and/or a You.com API key (YDC_API_KEY). No SearXNG yet? Start one with Docker. Crawling works without either.

Add it to your agent

One step for every agent on your machine

bash
uvx searxncrawl setup

setup detects Claude Code, Codex, Gemini CLI, Cursor, VS Code and Claude Desktop, asks for your SearXNG URL and, optionally, a You.com API key (hidden input, never printed), shows each config change and applies it only after you confirm. Every file it touches is backed up first, and setup --remove undoes it. More options are in MCP server.

Or per agent

[Add searxNcrawl to Cursor] [Install searxNcrawl in VS Code]

The buttons and commands below assume SearXNG at http://localhost:8888; change SEARXNG_URL if yours runs elsewhere, or add YDC_API_KEY for You.com.

Claude Code

bash
claude mcp add searxncrawl --env SEARXNG_URL=http://localhost:8888 -- uvx searxncrawl

Codex

bash
codex mcp add searxncrawl --env SEARXNG_URL=http://localhost:8888 -- uvx searxncrawl

VS Code

bash
code --add-mcp '{"name":"searxncrawl","command":"uvx","args":["searxncrawl"],"env":{"SEARXNG_URL":"http://localhost:8888"}}'

Cursor (~/.cursor/mcp.json), Claude Desktop and other clients that use the mcpServers format

json
{  "mcpServers": {    "searxncrawl": {      "command": "uvx",      "args": ["searxncrawl"],      "env": { "SEARXNG_URL": "http://localhost:8888" }    }  }}

The first crawl downloads Playwright's Chromium once (about 550 MB). For Docker, HTTP transport and other setups see Installation and MCP server.

  • Claude Desktop bundle: download searxncrawl-<version>.mcpb from GitHub Releases and open it in Claude Desktop.
  • Smithery users: use the direct installation above or the native bundle; see the Smithery transition.

Ask your agent

text
Search for the Crawl4AI quick start, crawl the official page and summarisehow to run a first crawl.

Your agent calls search, picks a result and calls crawl. It gets back clean Markdown instead of raw HTML.

Use the terminal

bash
uvx --from searxncrawl crawl https://modelcontextprotocol.io/docs/getting-started/introSEARXNG_URL=http://localhost:8888 uvx --from searxncrawl search "model context protocol" --max-results 5SEARXNG_URL=http://localhost:8888 uvx --from searxncrawl search "Python documentation" --max-results 3 --include-content

  • Standard installations and releases do not require Arcade.
  • For shared HTTP access, use an authenticated TLS proxy. Enable Host/Origin checks with FASTMCP_HTTP_HOST_ORIGIN_PROTECTION=true before startup; allowlists alone do not enable checks or authenticate callers.

How it works

    agent -- "MCP · STDIO or HTTP" --> server    server -- "search" --> searxng --> results    server -- "crawl · crawl_site" --> browser --> markdown

Results return to the agent as the tool response. Search and crawling are also available as the search and crawl CLI commands, crawling also as a Python API.

searxNcrawl exposes three MCP tools:

ToolWhat it does
searchQueries the configured providers (SearXNG, You.com) in parallel and returns one merged, deduplicated list with the source of each result. Filters: language, time range, safe search, paging; categories and engines for SearXNG. With include_content, also returns the Markdown of each result page in the same call.
crawlRenders one or many URLs in Chromium and returns Markdown or JSON with metadata and references.
crawl_siteFollows links from a seed URL within depth, page and timeout limits, tuned for documentation sites.

Both crawl tools drop sections that repeat within a page's Markdown (dedup_mode="exact"), can strip links for a smaller context (remove_links), and accept a Playwright storage_state for pages behind a login. Full parameters are in the MCP tools reference.

Private SearXNG instances

  • SEARXNG_EXTRA_HEADERS adds headers to SearXNG requests in both CLI and MCP, including access-gateway credentials and a custom User-Agent.
  • Values such as @~/.config/searxncrawl/cf_secret load secrets from files; absolute and ~/ paths are supported.
  • Invalid header configuration disables SearXNG with a value-free warning; a configured You.com provider remains available.
  • Setup and JSON examples: SearXNG configuration.

Why searxNcrawl

Hosted search and crawl APIs are quick to start with, but every call goes through someone else's service and is billed per request or credit. searxNcrawl runs on your own machine or server.

Self-hosted Firecrawl can search through SearXNG too; it runs as a multi-service stack (API, Playwright service, Redis, RabbitMQ, PostgreSQL and more), while searxNcrawl is a single Python process with Chromium, plus your SearXNG instance if you use one.

Where the others are a better fit: if you do not want to run a search provider and a browser yourself, a hosted API is less work, and Exa's semantic search index or Firecrawl's extraction features go beyond what searxNcrawl does today. Comparison based on each project's public repository and documentation in October 2026; corrections are welcome. Firecrawl is a trademark of its owner; searxNcrawl is not affiliated with it.

FAQ

Do I need SearXNG?

Only for the search tool, and only if you do not use You.com (YDC_API_KEY). crawl and crawl_site work without any search provider. SearXNG serves HTML only by default, so JSON output must be enabled (search.formats in settings.yml). Public instances may not enable it and often rate-limit automated requests, so run your own. Installation has a Docker one-liner.

Does it handle JavaScript-heavy pages?

Yes. Pages are rendered in Playwright's Chromium through Crawl4AI before they are converted to Markdown, so client-side content is captured.

Can it crawl pages behind a login?

Yes. Capture a session once with crawl-capture, then pass the saved storage_state file to crawl or crawl_site. See Session capture.

Can I run it remotely or share it with a team?
  • Start with --transport http (port 8000 by default) or Docker Compose (port 9555).
  • Put shared access behind an authenticated TLS proxy and connect clients to its /mcp endpoint.
  • Enable header protection and configure the externally visible Host and Origin allowlists.
Why is the first crawl slow?

The first crawl downloads Playwright's Chromium (about 550 MB on disk). Later runs reuse it. Set PLAYWRIGHT_AUTO_INSTALL=false where browsers are provisioned separately.

I used searxng-mcp. What changed?

searxng-mcp is deprecated in favour of searxNcrawl. It only searched SearXNG and could pick a random public instance; searxNcrawl adds page and site crawling but needs your own SEARXNG_URL (or a You.com key), as random public-instance selection is not included.

Do I need Arcade?
  • No. Connect directly over STDIO or HTTP for the standard setup.
  • The optional adapter connects a separately hosted worker to Arcade's authentication and gateway.
  • Arcade Cloud's current runner cannot install Playwright; the worker needs a compatible host.
