ask-search

Web search powered by SearxNG. Aggregates multiple search engines, no API key needed (optional Tavily backend).

Usage

ask-search "your query"                    # top 10 results
ask-search "query" --num 5                 # limit results
ask-search "AI news" --categories news     # news only
ask-search "query" --lang zh-CN            # Chinese results
ask-search "query" --urls-only             # URL list (pipe to web_fetch)
ask-search "query" --json                  # raw JSON

Agent Workflow

1. Run ask-search "topic" to get candidates
2. Check snippet — if enough, answer directly
3. If snippet truncated, use web_fetch on the URL for full content

Parameters

Setup

Requires SearxNG running locally, with json in search.formats (the bundled searxng/ Docker Compose setup does this). Set SEARXNG_URL if not on default port 8080.

bash install.sh            # installs the `ask-search` command (sudo, or: bash install.sh ~/.local/bin)

Optional Tavily backend: SEARCH_PROVIDER=tavily + TAVILY_API_KEY (--engines/--lang/--categories are ignored in this mode).

🔍 ask-search

Self-hosted web search for AI agents — no search API key needed

Works in OpenClaw · Claude Code · Antigravity · Any CLI

ask-search is a self-hosted web search CLI and MCP server for AI agents. It wraps SearxNG so Claude Code, OpenClaw, Antigravity or any shell can search Google, Bing, DuckDuckGo, Brave and more without a paid search API key. Tavily is an optional backend.

给 AI Agent 用的自托管联网搜索：包装 SearxNG，一条命令 / 一个 MCP server 就能聚合 Google、Bing、DuckDuckGo、Brave 等搜索结果，无需付费搜索 API key。

Python: CLI 3.8+; MCP server 3.10+ (required by the mcp package).

😡 The Problem

Your AI agent wants to search the web, but:

• Most search APIs need a key, cost money, and are rate limited
• Built-in web search sends your queries to third-party services

You just want your local agent to search Google and friends without a paid API.

✅ The Solution

ask-search wraps SearxNG — a self-hosted meta search engine that aggregates Google, Bing, DuckDuckGo, Brave and many more sources. One command, all results, no per-query fees.

📊 Compatibility

🚀 Quick Start

1. Start SearxNG (Docker Compose, recommended)

git clone https://github.com/ythx-101/ask-search
cd ask-search/searxng
cp .env.example .env      # then set SEARXNG_SECRET (python3 -c "import secrets; print(secrets.token_hex(32))")
docker compose up -d

Or with plain docker run:

docker run -d --name searxng \
  -p 127.0.0.1:8080:8080 \
  -e SEARXNG_SECRET=your-secret-key \
  -v "$PWD/searxng/searxng.yml:/etc/searxng/settings.yml" \
  searxng/searxng

2. Install the command

bash install.sh              # or: sudo bash install.sh, or: bash install.sh ~/.local/bin

3. Search

ask-search "hello world"

Already have SearxNG?

git clone https://github.com/ythx-101/ask-search
cd ask-search
bash install.sh
export SEARXNG_URL=http://localhost:8080   # if not the default
ask-search "hello world"

Your SearxNG must have json enabled in search.formats in settings.yml:

search:
  formats:
    - html
    - json

🔧 Usage

ask-search "query"                    # top 10 results
ask-search "query" --num 5            # limit results
ask-search "AI news" --categories news # news only
ask-search "query" --lang zh-CN       # language filter
ask-search "query" --urls-only        # URLs only (pipe to web_fetch)
ask-search "query" --json             # raw JSON
ask-search "query" -e google,brave    # specific engines

⚙️ Configuration

# SearxNG (default)
export SEARXNG_URL="http://localhost:8080"
ask-search "query"

# Tavily (opt-in)
export SEARCH_PROVIDER=tavily
export TAVILY_API_KEY=tvly-YOUR_API_KEY
ask-search "query"

claude mcp add ask-search -e SEARXNG_URL=http://localhost:8080 -- python3 /path/to/ask-search/mcp/server.py

MCP tools provided:

• web_search — search via SearxNG
• web_search_news — news search via SearxNG
• web_search_tavily — search via Tavily API (requires TAVILY_API_KEY)

🦞 OpenClaw Skill

Copy SKILL.md to your OpenClaw skills directory, or:

# OpenClaw skill loader
skill-add https://github.com/ythx-101/ask-search

Then in OpenClaw:

ask-search "latest news about X"

🤝 Agent Workflow

# 1. Search
ask-search "React Server Components performance 2026" --num 10

# 2. Got a promising URL? Deep-dive:
# Pass the URL to web_fetch / curl for full content

# 3. News mode
ask-search "GPT-5 release" --categories news --lang en

⚠️ SearxNG Setup Notes

• Must enable json in search.formats in settings.yml
• Bot detection may block requests from some IPs — add your server IP to pass_ip in limiter.toml
• Bind to 127.0.0.1 for security unless you need remote access

🧭 When to use

Privacy note: no third-party search API sees your queries; SearxNG forwards them to upstream engines from your own server.

❓ FAQ

Does ask-search need an API key? Not in the default SearxNG mode. In Tavily mode (SEARCH_PROVIDER=tavily) you need TAVILY_API_KEY.

How do I use it in Claude Code? Call the CLI from Bash (ask-search "query"), or register the MCP server (see MCP Integration above).

Why do I get 403 or "SearxNG did not return JSON"? json must be listed in search.formats in SearxNG's settings.yml (the bundled searxng/searxng.yml does this). If requests are blocked by the bot limiter, add your IP to pass_ip in limiter.toml.

Is it really private? No third-party search API sees your queries, but SearxNG still forwards them to upstream engines (Google, Bing, etc.) from your own server's IP.

How do I search in Chinese or get news only? ask-search "query" --lang zh-CN and ask-search "query" --categories news.

Can I use Tavily instead of SearxNG? Yes: export SEARCH_PROVIDER=tavily TAVILY_API_KEY=tvly-YOUR_API_KEY, and install tavily-python (pip install tavily-python; install.sh does this automatically when TAVILY_API_KEY is set). In Tavily mode --engines, --lang and --categories are ignored.

Does it work on Windows? It needs Python 3 and curl; install.sh is a bash script, so on Windows use WSL. Not tested on native Windows.

How is it different from Perplexica? Perplexica is a full AI search application with a UI. ask-search only returns search results (title, URL, snippet) for an agent to consume, via one CLI command or an MCP server.

🌐 Deep-Dive Limitations & Workarounds

ask-search returns URLs + snippets from search engine indexes. When your agent needs the full page content (deep-dive via curl / web_fetch), some sites will block depending on your server's network environment:

What works out of the box

Key insight: Search always works because SearxNG queries search engines (Google, Brave, etc.), not the target sites directly. The search engines have already indexed the content. The problem only appears when your agent tries to fetch the full page.

Solution 1: SOCKS proxy via residential IP

If you have a machine on a residential network (home server, laptop, etc.), create an SSH SOCKS tunnel:

# On your VPS/server:
ssh -f -N -D 127.0.0.1:1082 user@your-home-machine

# Then fetch through the proxy:
curl -x socks5h://127.0.0.1:1082 "https://reddit.com/r/example/comments/xxx.json"

For Reddit specifically, append .json to any post URL for structured data:

# Returns full post + all comments as JSON
curl -x socks5h://127.0.0.1:1082 \
  "https://www.reddit.com/r/LocalLLaMA/comments/xxxxx/post_title.json"

To persist the tunnel as a systemd service:

# /etc/systemd/system/socks-proxy.service
[Unit]
Description=SSH SOCKS Proxy for web scraping
After=network.target

[Service]
Type=simple
ExecStart=/usr/bin/ssh -N -D 127.0.0.1:1082 -o Serve
