What is the Exa AI MCP Server?
Connect your Exa AI (formerly Metaphor) account to any AI agent and take full control of your web research and data extraction workflows through natural conversation.
What you can do
- Semantic Search Orchestration — Perform AI-native searches that understand intent and meaning to retrieve the most relevant web pages programmatically
- Content Intelligence — Programmatically extract clean, parsed text or highlights from any URL, excluding ads and boilerplate automatically
- Similarity Discovery — Find pages semantically similar to a source URL to build comprehensive and high-fidelity research datasets
- Deep Data Mapping — Discover all reachable links on a domain and retrieve discovery metadata to understand site structures programmatically
- Search Filtering — Restricted searches by domain, category (company, blog, news), or discovery date directly through your agent
How it works
- Subscribe to this server
- Retrieve your API Key from the Exa AI dashboard (Settings > API Keys)
- Start searching the web semantically from Claude, Cursor, or any MCP client
No more manual keyword-based searching or messy scraping scripts. Your AI acts as your dedicated neural research assistant.
Who is this for?
- AI Developers — build RAG pipelines by programmatically ingesting semantically relevant web data using natural language
- Market Researchers — instantly identify competitors and find similar companies across the web using semantic discovery
- Content Analysts — automate the extraction of highlights and clean text from technical blogs and news without leaving your workspace

Frequently asked questions
How do I find my Exa AI API Key?
Log in to your Exa AI dashboard, and copy your unique API Key from the settings section.
What makes semantic search different?
Traditional search uses keywords. Semantic search uses neural embeddings to understand the meaning and context of your query, finding better matches.
Can I extract text from multiple URLs at once?
Yes! The extract_page_content tool accepts a JSON array of URLs and retrieves the parsed content for all of them programmatically.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
