💡 Key Use Cases in AI Workflows

Case 1: Research Assistant

In a research setting, an AI assistant can use Exa MCP Server to query web data related to specific topics. For instance, if a researcher needs up-to-date information on artificial intelligence startups in New York City:

Search for and summarize the latest news about artificial intelligence startups in new york.

The server processes this request through the Exa API and returns relevant articles with titles, URLs, and summaries.

Case 2: News Aggregator

AI can be used to aggregate news from various sources. By configuring the server, an AI tool can efficiently scrape and provide summarized headlines for specific categories:

Compile a list of top tech news stories published today.

The MCP server sends this prompt to the Exa API, processing and returning the filtered news articles.
