In the chat app your model can search the web. On the API it cannot. ModSearch puts the web back: web search, X search, page fetch. Free, no signup, no API key.
🥇 The strongest free web search plugin for DeepSeek Harness (dsh) 🥇

Models like DeepSeek and GLM have no web access, or a weak one. ModSearch is a plug-in that greatly strengthens web search, X search, and single-page fetch. It works the moment it lands: the default engine is Firecrawl's keyless tier, 1,000 free credits every month, with no account, no API key, and no card.
Hit a problem? Open an issue. Everything else is welcome on X: @liustack. What you built with it, which harness you are on, what should come next. New releases land there first. A community space is on the way.

Give it a blog link and ask what the post says. Twenty-five seconds later: a structured summary of the whole post, with no browser involved.

Give it no target at all, just "anything interesting in AI today?". Thirty-six seconds later: six sourced stories, with a closing note on which details came from aggregation and deserve a second look. The note comes from the uncertainty field.
An open-ended question comes back as six sourced stories with a stated confidence caveat
Ask dsh web for today's top AI stories. dsh's native search tool row runs straight on the modsearch engine chain, and eighteen seconds later three stories come back, each with a source link.

Ask which Node.js line is still in maintenance. read_page reads the release page and the release schedule in turn, and sixty seconds later the verdict arrives with a version status table and sources at the end.

Firecrawl works with zero setup. Every other engine is one command away. Keys live in ~/.modsearch/config.json (0600, masked when shown):
| Engine | Does | Free tier | Turn it on |
|---|---|---|---|
| Firecrawl (default) | web search + page fetch | keyless: 1,000 free credits/month, no signup. A free key adds your own 1,000/month | nothing, it works as installed |
| Antigravity CLI | web search + page fetch | free, browser sign-in | install agy and sign in |
| Tavily | web search | 1,000 credits/month, no card | modsearch config set tavily.apiKey <key> |
| Exa | web search | $10/month recurring credit (~1,400 searches), no card | modsearch config set exa.apiKey <key> |
| Grok Build | X (Twitter) search | rides SuperGrok or X Premium | install grok and sign in |
| local | page fetch | built in, nothing to install | nothing |
Keys can also come from the environment (TAVILY_API_KEY, EXA_API_KEY, FIRECRAWL_API_KEY). One engine can take multiple keys as a comma-separated value such as key-one,key-two, in either the config file or its environment variable. Multiple engines configured means automatic failover, best first. Every engine participates by default. Exclude one with modsearch config set tavily.enabled false. Using a Tavily-, Exa-, or Firecrawl-compatible third-party or self-hosted endpoint? Point the engine at it: modsearch config set tavily.baseURL <url>. Official endpoints stay built into the code and are never written as default config. Every knob, engine by engine, is in the configuration guide.
Step 1, hand it to your AI. Search and page fetch work as soon as the skill lands, on Firecrawl's free keyless quota, so installation is one message:
Install and configure the modsearch skill following INSTALL.md at https://github.com/liustack/modsearch, then run the health check and tell me the result.
Prefer a direct command? Install the same skill through skills.sh:
npx skills add liustack/modsearch
Step 2 (optional), add more free engines. Antigravity CLI writes better synthesized answers. A free Tavily, Exa, or Firecrawl key adds a personal quota on top of the keyless one. None requires a card. agy's browser sign-in is the only step that needs your hands:
curl -fsSL https://antigravity.google/cli/install.sh | bash
agy # sign in, then exit
Picked a key instead? Send one line to your AI: "set my tavily key to tvly-...".
dsh users have a path that never touches the command line. Settings → Plugins → Plugin config has a ModSearch card: pick the preferred engine, fill in an API key or a self-hosted endpoint, tick which engines join failover, hit save and it takes effect.
Once installed, you do not need to remember any commands. Just chat. Ask anything that needs checking, or paste a URL, and the skill triggers on its own: it picks an engine, runs the search or fetch, and the answer comes back with sources.

Proxy fake-IP mode (Clash, Clash Verge Rev, mihomo, Surge) works out of the box. DNS answers in 198.18.0.0/15 are treated as fake-IP placeholders with no switch needed. Literal URLs such as http://198.18.0.5/ stay blocked when allowPrivateNetwork is off. For other reserved ranges used by VPNs or hosts-file accelerators such as Steam++ / Watt Toolkit, see Blocked private network target.
