Exa MCP Server FAQ
What does Exa MCP Server do?
Exa MCP Server gives AI agents semantic web search powered by Exa's neural search engine. Unlike keyword-based search, Exa understands meaning — so queries like "startups using Rust for backend infrastructure" return precisely relevant results, not just keyword matches.
How is Exa different from Brave Search MCP?
Brave Search is keyword-based (like Google), returning results ranked by links and keywords. Exa uses neural embeddings to understand query intent, which excels at finding niche content, research papers, and specific types of pages that keyword search misses.
Is Exa MCP Server free?
Exa offers a free tier with 1,000 searches per month. Paid plans start at $99/month for 10,000 searches. The MCP server itself is open source. An Exa API key is required.
What tools does Exa MCP Server expose?
It exposes
exa_search (semantic or keyword search with filters), exa_find_similar (find pages similar to a given URL), and exa_get_contents (extract clean text from URLs). The search tool supports date filters, domain filters, and content type filters.How do I set up Exa MCP Server?
Install via
npx -y exa-mcp-server and set your EXA_API_KEY environment variable. Get a free API key at exa.ai. Add it to your Claude Desktop or Cursor MCP configuration.Source: exa.ai
