An MCP server implementation that integrates the Tavily Search API, providing optimized search capabilities for LLMs.
- Web Search: Perform web searches optimized for LLMs, with control over search depth, topic, and time range.
- Content Extraction: Extracts the most relevant content from search results, optimizing for quality and size.
- Optional Features: Include images, image descriptions, short LLM-generated answers, and raw HTML content.
- Domain Filtering: Include or exclude specific domains in search results.
- tavily_search
- Execute web searches using the Tavily Search API.
- Inputs:
query(string, required): The search query.search_depth(string, optional): "basic" or "advanced" (default: "basic").topic(string, optional): "general" or "news" (default: "general").days(number, optional): Number of days back for news search (default: 3).time_range(string, optional): Time range filter ("day", "week", "month", "year" or "d", "w", "m", "y").max_results(number, optional): Maximum number of results (default: 5).include_images(boolean, optional): Include related images (default: false).include_image_descriptions(boolean, optional): Include descriptions for images (default: false).include_answer(boolean, optional): Include a short LLM-generated answer (default: false).include_raw_content(boolean, optional): Include raw HTML content (default: false).include_domains(string[], optional): Domains to include.exclude_domains(string[], optional): Domains to exclude.
- 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.
-
Clone this repository somewhere on your computer:
git clone https://github.com/apappascs/tavily-search-mcp-server.git
-
Install dependencies & build the project:
cd tavily-search-mcp-servernpm install
npm run build
-
Open your Claude Desktop configuration file:
# On Mac: ~/Library/Application\ Support/Claude/claude_desktop_config.json # On Windows: %APPDATA%\Claude\claude_desktop_config.json -
Add one of the following to the
mcpServersobject in your config, depending on whether you want to run the server usingnpmordocker: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" } } } } -
Important Steps:
- Replace
/Users/<username>/<FULL_PATH...>/tavily-search-mcp-serverwith the actual full path to where you cloned the repository. - Add your Tavily API key in the
envsection. 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 .
- Replace
-
Restart Claude Desktop for the changes to take effect.
To install Tavily Search for Claude Desktop automatically via Smithery:
npx -y @smithery/cli install @apappascs/tavily-search-mcp-server --client claude-
Copy
.env.exampleto.env:cp .env.example .env
-
Update the
.envfile with your actual Tavily API key:TAVILY_API_KEY=your_api_key_here
Note: Never commit your actual API key to version control. The
.envfile is ignored by git for security reasons.
Start the server using Node.js:
node dist/index.jsFor sse transport:
node dist/sse.js-
Build the Docker image (if you haven't already):
docker build -t tavily-search-mcp-server:latest . -
Run the Docker container with:
For stdio transport:
docker run -it --rm -e TAVILY_API_KEY="your_api_key_here" tavily-search-mcp-server:latestFor 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_KEYto pass the value of yourTAVILY_API_KEYenvironment 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. -
Using docker compose
Run:
docker compose up -d
To stop the server:
docker compose down
