Exa MCP Server Project Detailed Introduction

Project Overview

The Exa MCP Server is a server application based on the Model Context Protocol (MCP), providing powerful web search capabilities for AI assistants (especially Claude Desktop). This project integrates the Exa AI Search API, enabling AI models to access real-time web information in a secure and controlled manner.

Technical Background

The Model Context Protocol (MCP) is an open standard that allows AI applications (such as Claude Desktop) to connect to external tools and data sources. It provides AI assistants with a clear and secure way to interact with local services and APIs, while maintaining user control.

• Git

Installation Methods

Method 1: NPM Global Installation

npm install -g exa-mcp-server

Method 2: Automatic Installation via Smithery

npx -y @smithery/cli install exa --client claude

Method 3: Source Code Installation

git clone https://github.com/exa-labs/exa-mcp-server.git
cd exa-mcp-server
npm install
npm run build
npm link

Claude Desktop Configuration

Add the following configuration to the Claude Desktop configuration file:

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

Usage Examples

Basic Search Examples

Search for the latest developments in quantum computing
Search for and summarize the latest news about AI startups in New York
Find the latest research papers on climate change solutions

Social Media Search

Search for @elonmusk's tweets about SpaceX
Find @samaltman's tweets about AI safety from last week

Business Research

Research exa.ai and find its pricing and feature information
Find competitors for companies that provide web search API services

Content Extraction

Extract the content of this research paper: https://arxiv.org/pdf/1706.03762

How It Works

1. Request Processing: The server receives search requests from Claude
2. API Call: Queries the Exa API using optimal settings (including real-time crawling)
3. Result Formatting: Formats the search results and returns them to Claude
4. Cache Management: Caches search results for future reference

Debugging and Testing

MCP Inspector

npx @modelcontextprotocol/inspector node ./build/index.js

This will open an interactive interface where you can:

• Explore server functionality
• Execute search queries
• View cached search results

Log Viewing

# macOS
tail -n 20 -f ~/Library/Logs/Claude/mcp*.log

# Windows
type "%APPDATA%\Claude\logs\mcp*.log"

Troubleshooting

Server Not Found

• Verify that the npm link is set up correctly
