Terraform Infrastructure as Code

Automate HashiCorp Cloud Platform (HCP) Terraform infrastructure management through type-safe TypeScript wrappers for Terraform Cloud and Terraform Enterprise.

When to Use This Skill

Invoke this skill when you need to:

• Create, configure, or update Terraform Cloud/Enterprise workspaces
• Trigger and monitor Terraform runs programmatically
• Manage workspace variables and variable sets
• Search for public Terraform modules, providers, or policies
• Access private registry modules and providers
• List organizations and projects in your Terraform Cloud/Enterprise account

This skill is ideal for infrastructure-as-code automation and programmatic HCP Terraform management workflows.

Prerequisites

Required:

• Terraform Cloud/Enterprise account
• TFE_TOKEN environment variable with a valid Terraform API token
• Docker (for running the MCP server)

MCP Server Command:

docker run -i --rm -e TFE_TOKEN=your_token hashicorp/terraform-mcp-server

Security Best Practices

⚠️ Important Security Guidelines:

• Never hardcode credentials: Always use environment variables for TFE_TOKEN
• Token security: Store tokens in secure credential managers or environment configuration
• Least privilege: Use workspace-specific or organization-specific tokens when possible
• Review before execution: Examine all generated code before running in production environments
• No secrets in code: Never commit tokens to version control

Example of secure token handling:

// ✅ Correct: Use environment variables
const token = process.env.TFE_TOKEN;

// ❌ Wrong: Hardcoded token
const token = "abc123..."; // NEVER DO THIS

Quick Start

import { initializeMCPClient, closeMCPClient } from "./scripts/client.js";
import { CreateWorkspace } from "./scripts/workspaces/index.js";
import { CreateRun } from "./scripts/runs/index.js";

// 1. Initialize connection
await initializeMCPClient({
  command: "docker",
  args: [
    "run", "-i", "--rm",
    "-e", `TFE_TOKEN=${process.env.TFE_TOKEN}`,
    "hashicorp/terraform-mcp-server"
  ]
});

try {
  // 2. Create a workspace
  const workspace = await CreateWorkspace({
    workspace_name: "my-infrastructure",
    terraform_org_name: "my-org",
    auto_apply: "false"
  });

  // 3. Trigger a run
  const run = await CreateRun({
    workspace_name: "my-infrastructure",
    terraform_org_name: "my-org",
    message: "Initial deployment"
  });
} finally {
  // 4. Clean up
  await closeMCPClient();
}

Common Workflows

Workflow 1: Create Infrastructure Workspace

// Use case: Setting up a new production environment for an API service
import { CreateWorkspace } from "./scripts/workspaces/index.js";

const workspace = await CreateWorkspace({
  workspace_name: "production-api",
  terraform_org_name: "acme-corp",
  description: "Production API infrastructure",
  auto_apply: "false",           // Require manual approval for production
  execution_mode: "remote",
  terraform_version: "1.6.0",
  tags: "production,api,critical"
});

Workflow 2: Find and Use Registry Module

// Use case: Discovering the right VPC module for AWS infrastructure
import { SearchModules, GetModuleDetails } from "./scripts/public-registry/index.js";

// 1. Search for VPC modules
const modules = await SearchModules({
  module_query: "vpc aws terraform-aws-modules"
});

// 2. Get detailed documentation for the best match
const moduleDetails = await GetModuleDetails({
  module_id: "terraform-aws-modules/vpc/aws/5.1.2"
});

console.log(moduleDetails.content[0].text);

Workflow 3: Configure Workspace Variables

// Use case: Setting up environment-specific configuration
import { CreateVariableSet, CreateVariableInVariableSet, AttachVariableSetToWorkspaces } from "./scripts/variables/index.js";

// 1. Create a variable set for AWS credentials
const varSet = await CreateVariableSet({
  terraform_org_name: "acme-corp",
  name: "aws-production-credentials",
  description: "AWS credentials for production workspaces",
  global: false
});

// 2. Add variables to the set
await CreateVariableInVariableSet({
  variable_set_id: varSet.id,
  key: "AWS_REGION",
  value: "us-east-1",
  category: "env",
  sensitive: false
});

// 3. Attach to workspaces
await AttachVariableSetToWorkspaces({
  variable_set_id: varSet.id,
  workspace_ids: "ws-123,ws-456,ws-789"
});

Workflow 4: Trigger and Monitor Runs

// Use case: Deploying infrastructure changes with monitoring
import { CreateRun, GetRunDetails } from "./scripts/runs/index.js";

// 1. Trigger a run
const run = await CreateRun({
  workspace_name: "production-api",
  terraform_org_name: "acme-corp",
  message: "Deploy v2.1.0 API changes",
  run_type: "plan-and-apply"
});

// 2. Monitor run status
const runDetails = await GetRunDetails({
  run_id: run.id
});

console.log(`Run status: ${runDetails.status}`);
console.log(`Plan output: ${runDetails.content[0].text}`);

Using the TypeScript Wrappers

Import from category indexes or individual files:

// Import from category index
import { CreateWorkspace, UpdateWorkspace, ListWorkspaces } from "./scripts/workspaces/index.js";

// Or import specific tool with types
import { CreateWorkspace, CreateWorkspaceInput, CreateWorkspaceOutput } from "./scripts/workspaces/createWorkspace.js";

All wrapper functions are fully typed with Input/Output interfaces. Use your IDE's autocomplete to discover parameters and see JSDoc documentation.

Error Handling

try {
  const result = await CreateWorkspace({
    workspace_name: "my-workspace",
    terraform_org_name: "my-org"
  });

  if (result.isError) {
    console.error("Workspace creation failed:", result.content);
  } else {
    console.log("Workspace created successfully");
  }
} catch (error) {
  console.error("MCP call failed:", error);
}

Testing This Skill

Before Using:

1. Verify TFE_TOKEN is set: echo $TFE_TOKEN
2. Confirm Docker is running: docker --version
3. Test MCP server connectivity:

   docker run -i --rm -e TFE_TOKEN=$TFE_TOKEN hashicorp/terraform-mcp-server
   

Troubleshooting:

• Connection errors: Verify Docker is running and token is valid
• Authentication failures: Check TFE_TOKEN has correct permissions for the operation
• Type errors: Ensure you're using the correct Input interface for each function

Architecture

• scripts/client.ts - MCP connection manager (initializeMCPClient, callMCPTool, closeMCPClient)
• scripts/{category}/ - Type-safe wrapper functions organized by category
  • Each tool has its own .ts file with Input/Output interfaces
  • index.ts provides barrel exports for convenient importing
• Full type safety - All interfaces generated from JSON Schema definitions

Limitations

This skill is NOT suitable for:

• Direct Terraform CLI operations (use Terraform CLI directly instead)
• Local Terraform state management (this is for Cloud/Enterprise only)
• Terraform configuration generation (use Terraform language skills instead)
• Non-Terraform infrastructure management
