🔍 My Tavily Search MCP Agent

I've created a powerful Model Context Protocol (MCP) Server powered by the Tavily API. With this, you can get high-quality, reliable information from business, news, finance, and politics - all through a robust and developer-friendly interface.

🌟 Why I Built Tavily Search MCP

In today's fast-paced digital landscape, I recognized the need for quick access to precise information. I needed a web search tool that works with my sequential thinking MCP server. That's why I developed Tavily Search MCP, which excels with:

⚡️ Lightning-fast async search responses
🛡️ Built-in fault tolerance with automatic retries
🎯 Clean, markdown-formatted results
🔍 Smart content snippets
🛠️ Comprehensive error handling
🖼️ Optional image results
📰 Specialized news search

🚀 Quick Start

Installing via Smithery

To install Tavily Search for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install mcp-tavily-search --client claude

Installing Manually

Here's how you can get up and running with my project in minutes:

# 1. Create environment
uv venv && .venv\Scripts\activate     # Windows
# OR
uv venv && source .venv/bin/activate  # Unix/MacOS

# 2. Install dependencies
uv pip install -e .

# 3. Set up configuration
echo TAVILY_API_KEY=your-key-here > .env

# 4. Start server
cd mcp_tavily_search && uv run server.py

Claude Desktop Setup

I've optimized the Claude Desktop experience with this configuration:

{
  "mcpServers": {
    "tavily-search": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/mcp-tavily-search/mcp_tavily_search",
        "run",
        "server.py"
      ],
      "env": {
        "TAVILY_API_KEY": "YOUR-API-KEY"
      }
    }
  }
}

📁 Configuration paths:

• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Unix/MacOS: ~/.config/Claude/claude_desktop_config.json

Project Architecture

I've designed a clean, modular structure to make development a breeze:

├── mcp_tavily_search/     # Core package
│   ├── server.py          # Server implementation
│   ├── client.py          # Tavily API client
│   ├── test_server.py     # Server tests

Key Components

Server (server.py)

• I've implemented the MCP protocol
• Request handling and routing
• Error recovery and health monitoring

Client (client.py)

• Tavily API integration
• Retry mechanism with exponential backoff
• Result formatting and processing
• Error handling and logging

Tests (test_server.py and test_client.py)

• Comprehensive unit tests for both server and client
• Ensures reliability and correctness of the implementation

Usage Examples

Here are some examples of how to use the enhanced search capabilities I've implemented:

1. Basic search:

{
  "name": "search",
  "arguments": {
    "query": "Latest news on artificial intelligence"
  }
}

2. Advanced search with images:

{
  "name": "search",
  "arguments": {
    "query": "Elon Musk SpaceX achievements",
    "search_depth": "advanced",
    "include_images": true,
    "max_results": 10
  }
}

3. News-specific search:

{
  "name": "search",
  "arguments": {
    "query": "Climate change impact on agriculture",
    "topic": "news",
    "max_results": 5
  }
}

4. Search with raw content:

{
  "name": "search",
  "arguments": {
    "query": "Python programming best practices",
    "include_raw_content": true,
    "max_results": 3
  }
}

Troubleshooting Guide

Connection Issues

If things don't work as expected, follow these steps I've outlined:

1. Verify your configuration paths
2. Check the Claude Desktop logs:

   # Windows
   type %APPDATA%\Claude\logs\latest.log
   # Unix/MacOS
   cat ~/.config/Claude/logs/latest.log
   

3. Test the server manually using the quick start commands

API Troubleshooting

If you're experiencing API issues:

1. Validate your API key permissions
2. Check your network connection
3. Monitor the API response in the server logs

Running Tests

To run the unit tests for this project, follow these steps:

1. Install the development dependencies:

   uv pip install -e ".[dev]"
   

2. Run the tests using pytest:

   pytest mcp_tavily_search
   

This will run all the tests in the mcp_tavily_search directory, including both test_client.py and test_server.py.
