Intelligent multi-provider search routing for AI agents. One query — the right provider, automatically.
Analyzes query intent and selects the best provider. No manual switching, no guesswork.
Automatically picks the right provider based on query intent. Research → Tavily. Shopping → Serper. Neural discovery → Exa.
If one provider is down or key is missing, seamlessly falls back to the next best option. Never fails silently.
Querit handles non-English queries natively. Region, language, and UI locale parameters supported across all providers.
Each provider excels at different query types. Web Search Plus knows which one to call.
| Provider | Best for | Config Key |
|---|---|---|
| Serper | Google results, shopping, news, local | SERPER_API_KEY |
| Tavily | Research, deep analysis, "how does X work" | TAVILY_API_KEY |
| Exa | Discovery, "similar to", neural search | EXA_API_KEY |
| Querit | Multilingual queries, AI-native search | QUERIT_API_KEY |
| Perplexity | Direct AI answers, summarized results | PERPLEXITY_API_KEY |
| You.com | RAG, real-time web, code snippets | YOU_API_KEY |
| SearXNG | Privacy-first, self-hosted, no API key | SEARXNG_BASE_URL |
Four ways in — same smart routing engine under the hood.
Native skill for OpenClaw agents. Auto-routing, confidence scoring, and multi-provider fallback built right in. Install once, search everywhere.
clawhub install web-search-plus
Standard MCP server. Works with Claude Desktop, Cursor, NanoBot, and any MCP-compatible client. One command to install.
uvx web-search-plus-mcp
Registers web_search_plus as a native OpenClaw tool. Multi-provider search with auto-routing — no subprocess overhead, direct Python execution.
openclaw plugins install clawhub:web-search-plus-plugin
Python port of web-search-plus for Hermes Agent. Multi-provider search (Serper, Tavily, Exa, Querit, Perplexity) with intelligent auto-routing. Same providers, same routing logic — native Hermes integration.
