Multi-provider web search and extraction MCP server with intelligent auto-routing, quality reports, and research mode

🔍 web-search-plus-mcp

Multi-provider web search and extraction MCP server with intelligent auto-routing.

web-search-plus-mcp is the standalone MCP packaging of Web Search Plus. It gives Claude Desktop, NanoBot, Cursor, and other MCP-compatible hosts access to the same Python routing engine family used by the Hermes/OpenClaw Web Search Plus tools.

Version note: web-search-plus-mcp uses its own MCP package version (0.2.1) while tracking the Web Search Plus engine family (v1.7). The Hermes plugin is versioned separately as hermes-web-search-plus v1.7.x.

✨ Features

• 10 search providers — Serper, Brave, Tavily, Exa, Querit, Linkup, Firecrawl, Perplexity, You.com, SearXNG
• 5 extract providers — Firecrawl, Linkup, Tavily, Exa, You.com
• Intelligent auto-routing — scores query intent and picks a provider automatically
• Quality reports — optional routing/result diagnostics
• Research mode — opt-in multi-provider search + top-source extraction with a time budget
• Zero-install run — uvx web-search-plus-mcp
• MCP-native — stdio server exposing web_search and web_extract

🚀 Quick Start

# Run instantly with uvx
