Exa MCP Server

Overview

Exa MCP Server brings AI-optimized web search to any MCP client. Exa’s neural search engine understands meaning, not just keywords — finding genuinely relevant technical content instead of SEO-optimized listicles.

How It Works

1. Get API key — Free tier at exa.ai
2. Install MCP server — npm install and configure
3. Search semantically — Agents search by meaning
4. Extract clean content — Full page content cleaned for LLMs

Use Cases

• Research — Find authoritative sources on any topic
• Competitive analysis — Find similar companies
• Content discovery — Find relevant articles and papers
• Fact-checking — Verify claims with real web sources
