A SerpApi-powered MCP server for web search capabilities using FastMCP

🔍 Gemini LLM-powered MCP Client integrated with Web Search Remote MCP Server

A local web search system that combines Google's Gemini LLM with a FastMCP tool-calling interface and a Streamlit UI. Uses SerpApi for live, real-time search results via a custom MCP server to show Remote MCP Server capabilities with Gemini LLM.

Features

• ✅ Google's Gemini API integration with Remote FastMCP Server
• ✅ Tool calling using FastMCP based Remote MCP Server
• ✅ Custom MCP Server with live web search via SerpApi

Installation

1. Clone the repository:

   git clone https://github.com/genieincodebottle/generative-ai.git
   cd genai-usecases\mcp\web_search_mcp
   

2. Open the Project in VS Code or any code editor.

3. Create a virtual environment:

   pip install uv #if uv not installed
   uv venv
   .venv\Scripts\activate # On Linux -> source venv/bin/activate
   

4. Create a requirements.txt file and add the following libraries:

     asyncio>=3.4.3
     aiohttp>=3.12.13
     python-dotenv>=1.1.0
     google-search-results>=2.4.2
     fastmcp>=2.8.1
     mcp>=1.9.4
     streamlit>=1.45.1
     requests>=2.32.4
     google-genai>=1.20.0
     anthropic>=0.54.0
     openai>=1.88.0
   

5. Install dependencies:

   uv pip install -r requirements.txt
   

6. Set up environment variables

   • Rename .env.example to .env
   • Update the file with your API keys:

   GOOGLE_API_KEY=your_key_here # Using the free-tier API 
   SERPAPI_API_KEY=your_serpapi_key # Using free-tier
   

   • 🔑 Get your API keys:

     For GOOGLE_API_KEY follow this -> https://aistudio.google.com/app/apikey

     For SERPAPI_API_KEY follow this -> https://serpapi.com/manage-api-key

7. Run the MCP Server at one terminal

   cd genai-usecases\mcp\web_search_mcp
   .venv\Scripts\activate
   python web_search_mcp_server.py --host localhost --port 8000
   

8. Run the Streamlit Client App in another terminal (Split VSCode terminal or Open window's terminal)

   cd genai-usecases\mcp\web_search_mcp
   .venv\Scripts\activate
   streamlit run gemini_mcp_client.py
   

9. Once started, go to:

   http://localhost:8501

   Use the sidebar to view Gemini API status, adjust model/temperature, and run queries with real-time web search using SerpApi.

   

⚙️ How It Works

• The Remote MCP server exposes tools (like web_search) via FastMCP over Streamable HTTP.
• The Streamlit app uses Gemini's function calling to request results from the Remote Web Saerch MCP server.
• Gemini combines LLM reasoning with live data via SerpApi using tool calling.
