## What is MCP? 🤔
The Model Context Protocol (MCP) is a system that lets AI apps, like Claude Desktop, connect to external tools and data sources. It gives a clear and safe way for AI assistants to work with local services and APIs while keeping the user in control.
## What does this server do? 🚀
The Exa MCP server:
- Enables AI assistants to perform web searches using Exa's powerful search API
- Provides structured search results including titles, URLs, and content snippets
- Handles rate limiting and error cases gracefully
## Prerequisites 📋
Before you begin, ensure you have:
- [Node.js](https://nodejs.org/) (v18 or higher)
- [Claude Desktop](https://claude.ai/download) installed
- An [Exa API key](https://dashboard.exa.ai/api-keys)
- Git installed
You can verify your Node.js installation by running:
```bash
node --version # Should show v18.0.0 or higher
````
## Installation 🛠️
### NPM Installation
```bash
npm install -g exa-mcp-server
```
### Using Smithery
To install the Exa MCP server for Claude Desktop automatically via [Smithery](https://smithery.ai/server/exa):
```bash
npx -y @smithery/cli install exa --client claude
```
### Manual Installation
1. Clone the repository:
```
git clone https://github.com/exa-labs/exa-mcp-server.git
cd exa-mcp-server
```
2. Install dependencies:
```
npm install --save axios dotenv
```
3. Build the project:
```
npm run build
```
4. Create a global link (this makes the server executable from anywhere):
```
npm link
```
## Configuration ⚙️
### 1. Configure Claude Desktop to recognize the Exa MCP server
You can find claude_desktop_config.json inside the settings of Claude Desktop app:
Open the Claude Desktop app and enable Developer Mode from the top-left menu bar.
Once enabled, open Settings (also from the top-left menu bar) and navigate to the Developer Option, where you'll find the Edit Config button. Clicking it will open the claude_desktop_config.json file, allowing you to make the necessary edits.
OR (if you want to open claude_desktop_config.json from terminal)
#### For macOS:
1. Open your Claude Desktop configuration:
```
code ~/Library/Application\ Support/Claude/claude_desktop_config.json
```
#### For Windows:
1. Open your Claude Desktop configuration:
```
code %APPDATA%\Claude\claude_desktop_config.json
```
### 2. Add the Exa server configuration:
```
{
"mcpServers": {
"exa": {
"command": "npx",
"args": ["/path/to/exa-mcp-server/build/index.js"],
"env": {
"EXA_API_KEY": "your-api-key-here"
}
}
}
}
```
Replace `your-api-key-here` with your actual Exa API key from [dashboard.exa.ai/api-keys](https://dashboard.exa.ai/api-keys).
### 3. Restart Claude Desktop
For the changes to take effect:
1. Completely quit Claude Desktop (not just close the window)
2. Start Claude Desktop again
3. Look for the 🔌 icon to verify the Exa server is connected
## Usage 🎯
Once configured, you can ask Claude to perform web searches. Here are some example prompts:
```
Can you search for recent developments in quantum computing?
```
```
Search for and summarize the latest news about artificial intelligence startups in new york.
```
```
Find and analyze recent research papers about climate change solutions.
```
The server will:
1. Process the search request
2. Query the Exa API
3. Return formatted results to Claude
4. Cache the search for future reference
## Features ✨
