Verdict

Pick tfmcp if you want a local (stdio) server that keeps data on your machine, and you need the broadest set of tools.

Pick Radar if you want the official, vendor-maintained server, and you prefer the more popular, battle-tested option.

Add tfmcp

Install / run
cargo install tfmcp

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

{
  "mcpServers": {
    "tfmcp": {
      "command": "/path/to/your/tfmcp",
      "args": [
        "mcp"
      ],
      "env": {
        "HOME": "/Users/yourusername",
        "PATH": "/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin",
        "TERRAFORM_DIR": "/path/to/your/terraform/project"
      }
    }
  }
}

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.
