web-search-plus-mcp 0.1.0

Multi-provider web search MCP server with intelligent auto-routing (Serper, Tavily, Exa)

web-search-plus-mcp

A Model Context Protocol (MCP) server that gives AI assistants access to multi-provider web search with intelligent auto-routing. Automatically selects the best search provider based on query intent — no manual switching needed.

Features

• 🔍 Intelligent auto-routing — picks the right provider per query
• ⚡ Zero config — uvx web-search-plus-mcp and you're done
• 🔌 MCP-native — works with Claude Desktop, NanoBot, and any MCP host
• 🔑 Bring your own keys — use whichever providers you have

Quick Start

# Run directly with uvx (no install needed)
uvx web-search-plus-mcp

# Or install globally
pip install web-search-plus-mcp
web-search-plus-mcp

Provider Routing

Provider	Best For	Required Key
Serper (Google)	General search, news, current events	SERPER_API_KEY
Tavily	Research, deep content extraction	TAVILY_API_KEY
Exa	Neural / semantic / discovery search	EXA_API_KEY

Auto-routing picks Serper for news/general queries, Tavily for research/analysis, and Exa for discovery-style or semantic queries. Falls back gracefully if a provider key is missing.

Claude Desktop Config

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "web-search-plus": {
      "command": "uvx",
      "args": ["web-search-plus-mcp"],
      "env": {
        "SERPER_API_KEY": "your_serper_key",
        "TAVILY_API_KEY": "your_tavily_key",
        "EXA_API_KEY": "your_exa_key"
      }
    }
  }
}

NanoBot Config

Add to your NanoBot config.json under mcp_servers:

{
  "mcp_servers": [
    {
      "name": "web-search-plus",
      "command": "uvx",
      "args": ["web-search-plus-mcp"],
      "env": {
        "SERPER_API_KEY": "your_serper_key",
        "TAVILY_API_KEY": "your_tavily_key",
        "EXA_API_KEY": "your_exa_key"
      }
    }
  ]
}

Provider	Free Tier	Get Key
Serper	2,500 free searches/month	serper.dev
