🧪 Test-box note: Docker isn't available on the box (no root); tested with HashiCorp's official 1.3.0 Linux binary from releases.hashicorp.com.

Install

claude mcp add terraform -- terraform-mcp-server stdio

Run in your terminal. This exact command is what our harness runs in Claude Code; see the results above.

{
  "mcpServers": {
    "terraform": {
      "command": "terraform-mcp-server",
      "args": [
        "stdio"
      ]
    }
  }
}

Save as .cursor/mcp.json. This exact config is what our harness runs in Cursor; see the results above.

{
  "mcpServers": {
    "terraform": {
      "command": "terraform-mcp-server",
      "args": [
        "stdio"
      ]
    }
  }
}

Add to claude_desktop_config.json and restart Claude Desktop. Tested on the Linux beta; see the results above.

[mcp_servers.terraform]
command = "terraform-mcp-server"
args = ["stdio"]

Add to ~/.codex/config.toml (shared by the ChatGPT (Codex) CLI and the ChatGPT desktop app; Codex runs inside the ChatGPT desktop app). Tested with the ChatGPT (Codex) CLI bundled in the ChatGPT desktop app; see the results above.
