About Exa Search

Exa Search is an exa search mcp server that connects an AI assistant to Exa's web search and content retrieval services. It lets an assistant find relevant material on the public web, then return usable content from search results or fetch content from URLs a user already knows. The hosted MCP service gives compatible clients a remote connection, so a user can add Exa search and retrieval without running a local server process.

What can Exa Search do?

The default Exa MCP tools cover web search and retrieval. The search tool returns relevant, ready-to-use content, while the fetch tool retrieves clean content from one or more specified URLs. These tools give an assistant a way to find pages and then read material from selected addresses.

Optional tools add more control or broader research workflows. Advanced search offers filters and controls for domains, dates, categories, location, freshness, highlights, summaries, and subpage crawling. The agent tool can handle multi-step research, list-building, enrichment, and structured output, but it requires an authenticated connection.

  • Search the web for relevant content.
  • Fetch clean content from known URLs.
  • Refine searches with filters, summaries, highlights, or subpage crawling.
  • Run multi-step research and request structured output through the agent tool.

How Exa Search connects and authenticates

The hosted service connects through a remote MCP endpoint, so the client does not need to run a local server process. Exa also documents a local package option for clients that need a locally run server. Authentication options include rate-limited keyless access, OAuth sign-in, or an API key. Exa names clients including ChatGPT, Codex, Claude, Grok, Cursor, and VS Code, and provides configuration guidance for additional clients such as Zed, Windsurf, Gemini CLI, and Warp. Support can vary by client version, so the published client list is not a compatibility guarantee.

Who is Exa Search best for?

Exa Search suits people who want an AI assistant to search the public web, retrieve content from known URLs, or run more involved research workflows. Keyless access is an option for limited use, but it is rate-limited and does not include the agent tool. Higher usage uses OAuth or an API key and is charged against the user's Exa team account, so users who need authenticated tools or more usage need an Exa account with the relevant credits or plan.

What Exa Search can access and change

The server accesses Exa's search and retrieval services. It returns public-web search results and content from URLs supplied to the fetch tool. Authenticated use is associated with the user's Exa team account. The verified documentation describes search and retrieval, not actions that alter pages or other external services, so this listing makes no claim that the server can change them. Keyless requests are rate-limited, agent_run is unavailable without OAuth or an API key, and an explicit tools URL parameter replaces the default tool list. A client using that parameter must include every tool it wants available.

Alternatives to Exa Search

For another web-search connection, Brave Search MCP is a comparable server to consider. Perplexity Official MCP Server is another search-focused option, while Tavily Official MCP Server offers a further alternative in the same broad category. Their inclusion here identifies similar directory listings, not a verified comparison of search results or quality.

Before you installSecurity checklist for MCP servers

An MCP server runs code and gives your AI assistant access to files, accounts or data. A few minutes of checking is worth it.

  1. Check the source. Make sure the repository belongs to the vendor or author you expect, that the vendor's own documentation links to it, and that it is actively maintained. Beware of lookalike names.
  2. Read what it can do. Look at the tools the server exposes and the permissions or scopes it asks for. Start with read-only access where the server allows it.
  3. Use the least access that works. Give it a dedicated API key or a narrowly scoped token, ideally on a test project or sandbox, not your production credentials.
  4. Pin versions and review updates. Install a specific version, read changes before upgrading, and do not run copied commands you do not understand.
  5. Treat what it returns as untrusted. Documents, web pages and tool results can contain text that tries to steer your AI assistant. Keep confirmation switched on for actions that write, delete, send or spend.
  6. Know where your data goes. Find out whether the server runs on your machine or is hosted, and what it sends to the vendor or to third parties.
  7. Keep a way back. Know how to revoke the key and remove the server from your client's configuration.
