Terraform MCP

Reads Terraform provider documentation and registry metadata so an agent writes HCL against the real schema instead of inventing arguments.

Official Go stdio

What it does

Reads Terraform provider documentation and registry metadata so an agent writes HCL against the real schema instead of inventing arguments. It does not run plan or apply — this is a documentation and validation aid, not an execution engineer. Docker is the simplest way to keep it updated.

Install

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

Client configuration

Paste this into your MCP client config (Claude Desktop, Cursor, or any client that reads mcpServers), then restart the client.

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

When to use it

Reach for this when the task needs infrastructure inside the agent loop. Skip it if a plain shell command or a one-off script is enough — every server you add costs context and adds a failure mode.

  • Kubernetes MCP — Talks to the Kubernetes API directly instead of shelling out to kubectl, so an agent can list contexts, read pod logs, and apply manifests without parsing command output
