_{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.

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

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

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

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

Codex

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

VS Code

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

{
  "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

Search for the Crawl4AI quick start, crawl the official page and summarise
how 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

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

Choose how to connect

• 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["AI agent<br/>Claude Code · Codex<br/>Cursor · VS Code"]
    server["searxNcrawl<br/>MCP server"]
    searxng["SearXNG (your instance)<br/>and/or You.com API"]
    browser["Crawl4AI +<br/>Playwright Chromium"]
    results["Merged results<br/>attributed per provider"]
    markdown["Deduplicated<br/>Markdown or JSON"]

    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:

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.
