How to connect

Your client connects to the URL. The first time, it asks you to sign in or, for some servers such as GitHub's, to add a token; the repository's README says which.

Terminal

claude mcp add --transport http exa https://mcp.exa.ai/mcp

~/.cursor/mcp.json

{
  "mcpServers": {
    "exa": {
      "url": "https://mcp.exa.ai/mcp"
    }
  }
}

~/.codex/config.toml

[mcp_servers.exa]
url = "https://mcp.exa.ai/mcp"

Terminal

claude mcp add --transport stdio exa -- npx -y exa-mcp-server

~/.cursor/mcp.json

{
  "mcpServers": {
    "exa": {
      "command": "npx",
      "args": [
        "-y",
        "exa-mcp-server"
      ]
    }
  }
}

~/.codex/config.toml

[mcp_servers.exa]
command = "npx"
args = ["-y", "exa-mcp-server"]
