Verdict

Pick Radar if you prefer the more popular, battle-tested option, and you want a hosted/remote server with nothing to install.

Pick Terraform MCP Server if you want a local (stdio) server that keeps data on your machine, and you want a verified, documented setup.

Add Radar

Install / run

curl -fsSL https://get.radarhq.io | sh

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "radar": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "http://localhost:9280/mcp"
      ]
    }
  }
}

Claude Desktop connects to remote servers through the `mcp-remote` proxy (installed on first run via npx). Restart Claude Desktop after saving.

Add Terraform MCP Server

Install / run

docker run -i --rm hashicorp/terraform-mcp-server

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "terraform-mcp-server": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "hashicorp/terraform-mcp-server"
      ]
    }
  }
}

Requires Docker to be installed and running.
