Setup Guide

1. Prerequisites

• Claude Desktop installed on your computer.
• A Tavily API key: a. Sign up for a Tavily API account. b. Choose a plan (Free tier available). c. Generate your API key from the Tavily dashboard.

2. Installation

1. Clone this repository somewhere on your computer:

   git clone https://github.com/apappascs/tavily-search-mcp-server.git 
   

2. Install dependencies & build the project:

   cd tavily-search-mcp-server
   

   npm install
   

   npm run build
   

3. Integration with Claude Desktop

1. Open your Claude Desktop configuration file:

   # On Mac:
   ~/Library/Application Support/Claude/claude_desktop_config.json
   
   # On Windows:
   %APPDATA%Claudeclaude_desktop_config.json
   

2. Add one of the following to the mcpServers object in your config, depending on whether you want to run the server using npm or docker:

   Option A: Using NPM (stdio transport)

   {
       "mcpServers": {
           "tavily-search-server": {
               "command": "node",
               "args": [
                   "/Users/<username>/<FULL_PATH...>/tavily-search-mcp-server/dist/index.js"
               ],
               "env": {
                   "TAVILY_API_KEY": "your_api_key_here"
               }
           }
       }
   }
   

   Option B: Using NPM (SSE transport)

   {
       "mcpServers": {
           "tavily-search-server": {
               "command": "node",
               "args": [
                   "/Users/<username>/<FULL_PATH...>/tavily-search-mcp-server/dist/sse.js"
               ],
               "env": {
                   "TAVILY_API_KEY": "your_api_key_here"
               },
               "port": 3001
           }
       }
   }
   

   Option C: Using Docker

   {
       "mcpServers": {
           "tavily-search-server": {
               "command": "docker",
               "args": [
                   "run",
                   "-i",
                   "--rm",
                   "-e",
                   "TAVILY_API_KEY",
                   "-v",
                   "/Users/<username>/<FULL_PATH...>/tavily-search-mcp-server:/app",
                   "tavily-search-mcp-server"
               ],
               "env": {
                   "TAVILY_API_KEY": "your_api_key_here"
               }
           }
       }
   }
   

3. Important Steps:

   • Replace /Users/<username>/<FULL_PATH...>/tavily-search-mcp-server with the actual full path to where you cloned the repository.
   • Add your Tavily API key in the env section. It’s always better to have secrets like API keys as environment variables.
   • Make sure to use forward slashes (/) in the path, even on Windows.
   • If you are using docker make sure you build the image first using docker build -t tavily-search-mcp-server:latest .

4. Restart Claude Desktop for the changes to take effect.

Installing via Smithery

To install Tavily Search for Claude Desktop automatically via Smithery:

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

Environment Setup (for npm)

1. Copy .env.example to .env:

   cp .env.example .env
   

2. Update the .env file with your actual Tavily API key:

   TAVILY_API_KEY=your_api_key_here
   

   Note: Never commit your actual API key to version control. The .env file is ignored by git for security reasons.

Running with NPM

Start the server using Node.js:

node dist/index.js

For sse transport:

node dist/sse.js

Running with Docker

1. Build the Docker image (if you haven’t already):

   docker build -t tavily-search-mcp-server:latest .
   

2. Run the Docker container with:

   For stdio transport:

   docker run -it --rm -e TAVILY_API_KEY="your_api_key_here" tavily-search-mcp-server:latest
   

   For sse transport:

   docker run -it --rm -p 3001:3001 -e TAVILY_API_KEY="your_api_key_here" -e TRANSPORT="sse" tavily-search-mcp-server:latest
   

   You can also leverage your shell’s environment variables directly, which is a more secure practice:

    docker run -it --rm -p 3001:3001 -e TAVILY_API_KEY=$TAVILY_API_KEY -e TRANSPORT="sse" tavily-search-mcp-server:latest
   

   Note: The second command demonstrates the recommended approach of using -e TAVILY_API_KEY=$TAVILY_API_KEY to pass the value of your TAVILY_API_KEY environment variable into the Docker container. This keeps your API key out of your command history, and it is generally preferred over hardcoding secrets in commands.

3. Using docker compose

   Run:

   docker compose up -d
   

   To stop the server:

   docker compose down
