# Exa

> Real-time web search for AI models and assistants

The Exa MCP Server brings real-time web search and content extraction capabilities to your Caylex AI agents, powered by Exa's search API. Agents can perform intelligent web searches, crawl and extract content from specific URLs, and retrieve code-focused context for technical research and development tasks. This makes the server well-suited for use cases such as academic research, competitive analysis, market intelligence, and staying current with rapidly evolving topics. The server is open-source and backed by Exa's purpose-built search infrastructure, designed specifically for AI agent consumption rather than traditional keyword-based retrieval.

<Warning>
  **Prerequisites:**

  * An active Exa account with a valid API key, obtainable from the Exa dashboard.
</Warning>

<Note>
  **Important API details:**

  * An Exa API key is required to authenticate requests; the key must be provided when connecting the server in Caylex.
  * The server supports OAuth-based authentication in addition to API key header authentication.
  * Web search results reflect real-time data from Exa's index, so result freshness depends on Exa's crawl schedule.
</Note>
