Intro

Exa MCP Server connects clients to Exa’s hosted web/code search tools via a remote MCP URL, with simple config for Cursor, VS Code, Claude Code, and Codex.

  • Best for: agent builders who want high-quality search tools without running local infra
  • Works with: MCP clients with HTTP transport (Cursor/VS Code/Claude Code/Codex), Exa API key
  • Setup time: 5–15 minutes

Practical Notes

  • Data point: it’s a hosted remote MCP URL (no local server required).
  • Quant: budget 1–2 minutes to validate auth and a first tool call.

Pattern: keep search as a dedicated tool

In agent setups, keep search separate from browsing:

  • search finds candidates (URLs/snippets),
  • browsing fetches and verifies content.

This reduces hallucinations because the agent can cite the tool result, then confirm with a second step.

Operational tips

  • Prefer HTTP transport for multi-user clients.
  • Treat the API key like any other secret (CI secret store, not in git).

FAQ

Q: Do I have to run this server myself? A: No. The repo documents a hosted endpoint you can connect to directly.

Q: Which transport should I use? A: Use HTTP transport when your client supports it.

Q: What if tools fail? A: Verify the MCP URL is reachable and the API key is configured correctly in your client.
