Exa MCP Server 🔍

A Model Context Protocol (MCP) server lets AI assistants like Claude use the Exa AI Search API for web searches. This setup allows AI models to get real-time web information in a safe and controlled way.

Specify which tools to enable:

{
  "mcpServers": {
    "exa": {
      "command": "npx",
      "args": [
        "-y",
        "exa-mcp-server",
        "--tools=web_search_exa,research_paper_search,company_research,crawling,competitor_finder,linkedin_search,wikipedia_search_exa,github_search"
      ],
      "env": {
        "EXA_API_KEY": "your-api-key-here"
      }
    }
  }
}

For enabling multiple tools, use a comma-separated list:

{
  "mcpServers": {
    "exa": {
      "command": "npx",
      "args": [
        "-y",
        "exa-mcp-server",
        "--tools=web_search_exa,research_paper_search,company_research,crawling,competitor_finder,linkedin_search,wikipedia_search_exa,github_search"

      "env": {
        "EXA_API_KEY": "your-api-key-here"

    }
  }
}

If you don't specify any tools, all tools enabled by default will be used.
