Prerequisites

• Python 3.11 or later
• A Tavily API key (obtain from Tavily's website)
• uv Python package manager (recommended)

Installation

Option 1: Using pip or uv

# With pip
pip install mcp-tavily

# Or with uv (recommended)
uv add mcp-tavily

You should see output similar to:

Resolved packages: mcp-tavily, mcp, pydantic, python-dotenv, tavily-python [...]
Successfully installed mcp-tavily-0.1.4 mcp-1.0.0 [...]

Option 2: From source

# Clone the repository
git clone https://github.com/RamXX/mcp-tavily.git
cd mcp-tavily

# Create a virtual environment (optional but recommended)
python -m venv .venv
source .venv/bin/activate  # On Windows: .venv\Scripts\activate

# Install dependencies and build
uv sync  # Or: pip install -r requirements.txt
uv build  # Or: pip install -e .

# To install with test dependencies:
uv sync --dev  # Or: pip install -r requirements-dev.txt

During installation, you should see the package being built and installed with its dependencies.

Usage with VS Code

For quick installation, use one of the one-click install buttons below:

For manual installation, add the following JSON block to your User Settings (JSON) file in VS Code. You can do this by pressing Ctrl + Shift + P and typing Preferences: Open User Settings (JSON).

Optionally, you can add it to a file called .vscode/mcp.json in your workspace. This will allow you to share the configuration with others.

Note that the mcp key is not needed in the .vscode/mcp.json file.

{
  "mcp": {
    "inputs": [
      {
        "type": "promptString",
        "id": "apiKey",
        "description": "Tavily API Key",
        "password": true
      }
    ],
    "servers": {
      "tavily": {
        "command": "uvx",
        "args": ["mcp-tavily"],
        "env": {
          "TAVILY_API_KEY": "${input:apiKey}"
        }
      }
    }
  }
}

Configuration

API Key Setup

The server requires a Tavily API key, which can be provided in three ways:

1. Through a .env file in your project directory:

   TAVILY_API_KEY=your_api_key_here
   

2. As an environment variable:

   export TAVILY_API_KEY=your_api_key_here
   

3. As a command-line argument:

   python -m mcp_server_tavily --api-key=your_api_key_here
   

Configure for Claude.app

Add to your Claude settings:

"mcpServers": {
  "tavily": {
    "command": "python",
    "args": ["-m", "mcp_server_tavily"]
  },
  "env": {
    "TAVILY_API_KEY": "your_api_key_here"
  }
}

If you encounter issues, you may need to specify the full path to your Python interpreter. Run which python to find the exact path.

Usage Examples

For a regular web search:

Tell me about Anthropic's newly released MCP protocol

To generate a report with domain filtering:

Tell me about redwood trees. Please use MLA format in markdown syntax and include the URLs in the citations. Exclude Wikipedia sources.

To use answer search mode for direct answers:

I want a concrete answer backed by current web sources: What is the average lifespan of redwood trees?

For news search:

Give me the top 10 AI-related news in the last 5 days

Testing

The project includes a comprehensive test suite. To run the tests:

1. Install test dependencies:

   source .venv/bin/activate  # If using a virtual environment
   uv sync --dev  # Or: pip install -r requirements-dev.txt
   

2. Run the tests:

   ./tests/run_tests.sh
   

You should see output similar to:

# Using npx
npx @modelcontextprotocol/inspector python -m mcp_server_tavily

# For development
cd path/to/mcp-tavily
npx @modelcontextprotocol/inspector python -m mcp_server_tavily
