Tavily MCP Demo

The Model Context Protocol (MCP) is an open standard that enables AI systems to interact seamlessly with various data sources and tools, facilitating secure, two-way connections.

Developed by Anthropic, the Model Context Protocol (MCP) enables AI assistants like Claude to seamlessly integrate with Tavily's advanced search and data extraction capabilities. This integration provides AI models with real-time access to web information, complete with sophisticated filtering options and domain-specific search features.

The Tavily MCP server provides:

Seamless interaction with the tavily-search and tavily-extract tools
Real-time web search capabilities through the tavily-search tool
Intelligent data extraction from web pages via the tavily-extract tool

Prerequisites 🔧

Tavily API key
- If you don't have a Tavily API key, you can sign up for a free account here
Claude Desktop or Cursor
Node.js (v20 or higher)
- You can verify your Node.js installation by running:
  - node --version
Git installed (only needed if using Git installation method)
- On macOS: brew install git
- On Linux:
  - Debian/Ubuntu: sudo apt install git
  - RedHat/CentOS: sudo yum install git
- On Windows: Download Git for Windows

Tavily MCP server installation ⚡

To install the tavily-mcp server, you can use the following methods:

Running with NPX
Git installation

1. Running with NPX

npx -y tavily-mcp@0.1.3

Although you can launch a server on its own, it's not particularly helpful in isolation. Instead, you should integrate it into an MCP client. Below is an example of how to configure the Claude Desktop app to work with the tavily-mcp server.

Configuring MCP Clients ⚙️

This repository will explain how to configure both Cursor and Claude Desktop to work with the tavily-mcp server.

Configuring Cursor 🖥️

Note: Requires Cursor version 0.45.6 or higher

To set up the Tavily MCP server in Cursor:

Open Cursor Settings
Navigate to Features > MCP Servers
Click on the "+ Add New MCP Server" button
Fill out the following information:
- Name: Enter a nickname for the server (e.g., "tavily-mcp")
- Type: Select "command" as the type
- Command: Enter the command to run the server:
```
env TAVILY_API_KEY=your-api-key npx -y tavily-mcp@0.1.3
```
  Important: Replace your-api-key with your Tavily API key. You can get one at app.tavily.com/home

After adding the server, it should appear in the list of MCP servers. You may need to manually press the refresh button in the top right corner of the MCP server to populate the tool list.

The Composer Agent will automatically use the Tavily MCP tools when relevant to your queries. It is better to explicitly request to use the tools by describing what you want to do (e.g., "User tavily-search to search the web for the latest news on AI"). On mac press command + L to open the chat, select the composer option at the top of the screen, beside the submit button select agent and submit the query when ready.

Cursor Interface Example

Configuring the Claude Desktop app 🖥️

For macOS:

# Create the config file if it doesn't exist
touch "$HOME/Library/Application Support/Claude/claude_desktop_config.json"

# Opens the config file in TextEdit 
open -e "$HOME/Library/Application Support/Claude/claude_desktop_config.json"

# Alternative method using Visual Studio Code (requires VS Code to be installed)
code "$HOME/Library/Application Support/Claude/claude_desktop_config.json"

For Windows:

code %APPDATA%\Claude\claude_desktop_config.json

Add the Tavily server configuration:

Replace your-api-key-here with your actual Tavily API key.

{
  "mcpServers": {
    "tavily-mcp": {
      "command": "npx",
      "args": ["-y", "tavily-mcp@0.1.2"],
      "env": {
        "TAVILY_API_KEY": "your-api-key-here"
      }
    }
  }
}

2. Git Installation

Clone the repository:

git clone https://github.com/tavily-ai/tavily-mcp.git
cd tavily-mcp

Install dependencies:

npm install

Build the project:

npm run build

Configuring the Claude Desktop app ⚙️

Follow the configuration steps outlined in the Configuring the Claude Desktop app section above, using the below JSON configuration.

Replace your-api-key-here with your actual Tavily API key and /path/to/tavily-mcp with the actual path where you cloned the repository on your system.

{
  "mcpServers": {
    "tavily": {
      "command": "npx",
      "args": ["/path/to/tavily-mcp/build/index.js"],
      "env": {
        "TAVILY_API_KEY": "your-api-key-here"
      }
    }
  }
}

Usage in Claude Desktop App 🎯

Once the installation is complete, and the Claude desktop app is configured, you must completely close and re-open the Claude desktop app to see the tavily-mcp server. You should see a hammer icon in the bottom left of the app, indicating available MCP tools, you can click on the hammer icon to see more detial on the tavily-search and tavily-extract tools.

Troubleshooting 🛠️

Common Issues

Server Not Found
- Verify the npm installation by running npm --verison
- Check Claude Desktop configuration syntax by running code ~/Library/Application\ Support/Claude/claude_desktop_config.json
- Ensure Node.js is properly installed by running node --version
NPX related issues

If you encounter errors related to npx, you may need to use the full path to the npx executable instead.
You can find this path by running which npx in your terminal, then replace the "command": "npx" line with "command": "/full/path/to/npx" in your configuration.

API Key Issues
- Confirm your Tavily API key is valid
- Check the API key is correctly set in the config
- Verify no spaces or quotes around the API key
