# Integration Tests
This directory contains integration tests for the Terraform MCP Server. These tests verify the server's functionality by starting a Node.js server process for each test and making real requests.
## Structure
The integration tests are organized as follows:
- `tests/integration/helpers.ts`: Helper functions for running tests
- `tests/integration/resources.test.ts`: Tests for the Resources API
- `tests/integration/tools.test.ts`: Tests for the Tools API
- `tests/integration/tfc.test.ts`: Tests for Terraform Cloud functionality
## Running Tests
```bash
# Run all integration tests
npm run test:integration
# Run specific test files
npm run test:integration -- -t "should list providers"
# Run with a specific workspace name
TEST_WORKSPACE_ID=my-workspace-name npm run test:integration
```
## Test Requirements
- Some tests require external credentials:
- `TFC_TOKEN`: For Terraform Cloud tests (stored in environment or config.ts)
- Workspace `mcp-integration-test` must exist in your organization for TFC tests
## Default Values
The integration tests use the following defaults:
- Organization: `pthrasher_v2` (can be overriden with `TEST_ORG` env var)
- Workspace name: `mcp-integration-test` (can be overriden with `TEST_WORKSPACE_ID` env var)
## Error Handling
The integration tests verify success responses and will fail the test if:
1. API returns an error result
2. API returns a 404 status
3. API returns error content
4. Timeout waiting for server to start (7 seconds)
5. Timeout waiting for server response (5 seconds)
## Adding New Tests
When adding new tests:
1. Use the helper functions in `helpers.ts`
2. Always use `assertSuccessResponse(response)` to validate responses
3. For Terraform Cloud tests, use the sequence pattern in `tfc.test.ts`
4. Set appropriate timeouts for your tests
## Differences from Unit Tests
- Integration tests start actual Node.js server processes
- They make real API calls to external services
- They test the full request/response cycle
- Tests take longer to run than unit tests
## Migration from Shell Scripts
These integration tests replace the previous shell scripts:
- `test.sh`
- `test-tfc.sh`
- `test-resources.sh`
The Jest tests provide better error reporting, organization, and isolation compared to shell scripts.

# Terraform Registry MCP Server
A Model Context Protocol (MCP) server that provides tools for interacting with the Terraform Registry API. This server enables AI agents to query provider information, resource details, and module metadata.
> [!IMPORTANT]
> This project was used as a PoC for a new official [Terraform MCP server](https://github.com/hashicorp/terraform-mcp-server). This repo has been archived in favor of that one.
## Installation
### Installing in Cursor
To install and use this MCP server in [Cursor](https://cursor.sh/):
1. In Cursor, open Settings (⌘+,) and navigate to the "MCP" tab.
2. Click "+ Add new MCP server."
3. Enter the following:
- Name: terraform-registry
- Type: command
- Command: npx -y terraform-mcp-server
4. Click "Add" then scroll to the server and click "Disabled" to enable the server.
5. Restart Cursor, if needed, to ensure the MCP server is properly loaded.
### Installing in Claude Desktop
To install and use this MCP server in Claude Desktop:
1. In Claude Desktop, open Settings (⌘+,) and navigate to the "Developer" tab.
2. Click "Edit Config" at the bottom of the window.
3. Edit the file (`~/Library/Application Support/Claude/claude_desktop_config.json`) to add the following code, then Save the file.
```json
{
"mcpServers": {
"terraform-registry": {
"command": "npx",
"args": ["-y", "terraform-mcp-server"]
}
}
}
```
4. Restart Claude Desktop to ensure the MCP server is properly loaded.
## Tools
The following tools are available in this MCP server:
### Core Registry Tools
| Tool | Description |
|------|-------------|
| `providerDetails` | Gets detailed information about a Terraform provider |
| `resourceUsage` | Gets example usage of a Terraform resource and related resources |
| `moduleSearch` | Searches for and recommends Terraform modules based on a query |
| `listDataSources` | Lists all available data sources for a provider and their basic details |
| `resourceArgumentDetails` | Fetches comprehensive details about a resource type's arguments |
| `moduleDetails` | Retrieves detailed metadata for a Terraform module |
| `functionDetails` | Gets details about a Terraform provider function |
| `providerGuides` | Lists and views provider-specific guides and documentation |
| `policySearch` | Searches for policy libraries in the Terraform Registry |
| `policyDetails` | Gets detailed information about a specific policy library |
### Terraform Cloud Tools
These tools require a Terraform Cloud API token (`TFC_TOKEN`):
| Tool | Description |
|------|-------------|
| `listOrganizations` | Lists all organizations the authenticated user has access to |
| `privateModuleSearch` | Searches for private modules in an organization |
| `privateModuleDetails` | Gets detailed information about a private module |
| `explorerQuery` | Queries the Terraform Cloud Explorer API to analyze data |
| `listWorkspaces` | Lists workspaces in an organization |
| `workspaceDetails` | Gets detailed information about a specific workspace |
| `lockWorkspace` | Locks a workspace to prevent runs |
| `unlockWorkspace` | Unlocks a workspace to allow runs |
| `listRuns` | Lists runs for a workspace |
| `runDetails` | Gets detailed information about a specific run |
| `createRun` | Creates a new run for a workspace |
| `applyRun` | Applies a run that's been planned |
| `cancelRun` | Cancels a run that's in progress |
| `listWorkspaceResources` | Lists resources in a workspace |
## Resources
The MCP server supports the following resource URIs for listing and reading via the `resources/*` methods:
| Resource Type | Example URI(s) | Description |
|---------------|----------------|-------------|
| **Providers** | `terraform:providers` | List all namespaces/providers |
| | `terraform:provider:<namespace>/<name>` | Get details for a specific provider |
| **Provider Versions** | `terraform:provider:<namespace>/<name>/versions` | List available versions for a provider |
| **Provider Resources** | `terraform:provider:<namespace>/<name>/resources` | List resources for a provider |
| | `terraform:resource:<namespace>/<name>/<resource_name>` | Get details for a specific resource type |
| **Provider Data Sources** | `terraform:provider:<namespace>/<name>/dataSources` | List data sources for a provider |
| | `terraform:dataSource:<namespace>/<name>/<data_source_name>` | Get details for a specific data source |
| **Provider Functions** | `terraform:provider:<namespace>/<name>/functions` | List functions for a provider |
| | `terraform:function:<namespace>/<name>/<function_name>` | Get details for a specific function |
The server also supports `resources/templates/list` to provide templates for creating:
- `terraform:provider`
- `terraform:resource`
- `terraform:dataSource`
## Prompts
The following prompts are available for generating contextual responses:
| Prompt | Description | Required Arguments |
|--------|-------------|-------------------|
| `migrate-clouds` | Generate Terraform code to migrate infrastructure between cloud providers | `sourceCloud`, `targetCloud`, `terraformCode` |
| `generate-resource-skeleton` | Helps users quickly scaffold new Terraform resources with best practices | `resourceType` |
| `optimize-terraform-module` | Provides actionable recommendations for improving Terraform code | `terraformCode` |
| `migrate-provider-version` | Assists with provider version upgrades and breaking changes | `providerName`, `currentVersion`, `targetVersion`, `terraformCode` (optional) |
| `analyze-workspace-runs` | Analyzes recent run failures and provides troubleshooting guidance for Terraform Cloud workspaces | `workspaceId`, `runsToAnalyze` (optional, default: 5) |
### Known Issues with Prompts
**Note**: There is a known issue with the `getPrompt` functionality that can cause server crashes. The server properly registers prompts and can list them, but direct requests using the `getPrompt` method may cause connectivity issues. This is being investigated and may be related to SDK compatibility or implementation details. Until resolved, use `listPrompts` to see available prompts but avoid direct `getPrompt` calls.
## Running the Server
The server runs using stdio transport for MCP communication:
```bash
npm install
npm start
```
### Configuration with Environment Variables
The server can be configured using environment variables:
| Environment Variable | Description | Default Value |
|---------------------|-------------|---------------|
| `TERRAFORM_REGISTRY_URL` | Base URL for Terraform Registry API | https://registry.terraform.io |
| `DEFAULT_PROVIDER_NAMESPACE` | Default namespace for providers | hashicorp |
| `LOG_LEVEL` | Logging level (error, warn, info, debug) | info |
| `REQUEST_TIMEOUT_MS` | Timeout for API requests in milliseconds | 10000 |
| `RATE_LIMIT_ENABLED` | Enable rate limiting for API requests | false |
| `RATE_LIMIT_REQUESTS` | Number of requests allowed in time window | 60 |
| `RATE_LIMIT_WINDOW_MS` | Time window for rate limiting in milliseconds | 60000 |
| `TFC_TOKEN` | Terraform Cloud API token for private registry access (optional) | |
Example usage with environment variables:
```bash
# Set environment variables
export LOG_LEVEL="debug"
export REQUEST_TIMEOUT_MS="15000"
export TFC_TOKEN="your-terraform-cloud-token"
# Run the server
npm start
```

# Terraform MCP Server Testing
This document provides information about the testing approach for the Terraform MCP Server.
## Overview
The project uses Jest for unit and integration tests, covering:
- **Tools**: Tests for all MCP tool handlers (Registry and TFC)
- **Resources**: Tests for the Resources API endpoints
- **Prompts**: Tests for MCP prompt functionality
- **Integration**: End-to-end tests for all components
## Running Tests
```bash
# Run all tests
npm test
# Run specific test patterns
npm test -- --testPathPattern=tools
npm test -- --testPathPattern=resources
npm test -- --testPathPattern=prompts
# Run integration tests
npm run test:integration
```
## Test Structure
### Tools Tests
Tests for MCP tools that interact with the Terraform Registry and Terraform Cloud:
- Registry tools (provider details, resource usage, module search)
- Terraform Cloud tools (workspace management, runs, resources)
### Resources Tests
Tests for the MCP Resources API endpoints:
- `resources/list` - Lists resources by URI
- `resources/read` - Reads a specific resource
- `resources/templates/list` - Lists available resource templates
- `resources/subscribe` - Tests subscription functionality
### Prompt Tests
Tests for MCP prompts in the `src/tests/prompts` directory:
| Prompt | Description | Key Arguments |
|--------|-------------|---------------|
| `migrate-clouds` | Cloud migration | `sourceCloud`, `targetCloud` |
| `generate-resource-skeleton` | Resource scaffolding | `resourceType` |
| `optimize-terraform-module` | Code optimization | `terraformCode` |
| `migrate-provider-version` | Version upgrades | `providerName`, `currentVersion` |
| `analyze-workspace-runs` | TFC run analysis | `workspaceId`, `runsToAnalyze` |
Run prompt tests specifically with:
```bash
npm test -- --testPathPattern=prompts
```
### Integration Tests
End-to-end tests that verify the complete server functionality:
- Tool call handling
- Resource listing and reading
- Error handling and validation
## Known Issues
### getPrompt Test Failures
Currently, tests for the `getPrompt` functionality are disabled due to consistent timeouts and server crashes. This is a known issue that needs further investigation. The issue might be related to how the SDK handles prompt requests or an implementation detail in the server.
## Environment Variables
Tests use sensible defaults, but you can override these with environment variables:
```bash
# For Terraform Cloud tests
TEST_ORG=my-org TEST_WORKSPACE_ID=my-workspace npm run test:integration
# Configure logging level
LOG_LEVEL=debug npm test
```

# Terraform Registry API Usage
This document outlines our understanding and use of the Terraform Registry API for the terraform-mcp-server project.
## API Endpoints
### Provider Endpoints
- **Provider Lookup**: `https://registry.terraform.io/v1/providers/{namespace}/{provider}`
- Used in `providerDetails` tool
- Returns provider metadata including versions
- **Provider Schema**: `https://registry.terraform.io/v1/providers/{namespace}/{provider}/{version}/download/{os}/{arch}`
- Used as a fallback in `listDataSources` and `resourceArgumentDetails` tools
- Returns detailed provider schema with resources and data sources
### Resource Endpoints
- **Resource Details**: `https://registry.terraform.io/v1/providers/{namespace}/{provider}/resources/{resource}`
- Used in `resourceArgumentDetails`
- This endpoint has been reported as returning 404 errors
- We now use a fallback approach when this fails
- **Resource Documentation**: `https://registry.terraform.io/providers/{namespace}/{provider}/latest/docs/resources/{resource}`
- HTML documentation page that can be parsed for examples
- Used for retrieving resource details when API endpoints fail
### Module Endpoints
- **Module Search**: `https://registry.terraform.io/v1/modules/search?q={query}`
- Used in `moduleSearch` tool
- Returns modules matching the search query
- **Module Details**: `https://registry.terraform.io/v1/modules/{namespace}/{name}/{provider}`
- Used in `moduleDetails` tool
- Returns module metadata including versions and inputs
## API Changes and Issues
As of version 0.12.0, we've encountered some issues with the Terraform Registry API:
1. **Resource Details Endpoint Failures**:
- The `/v1/providers/{namespace}/{provider}/resources/{resource}` endpoint often returns 404 errors
- We've implemented fallbacks using documentation URLs to handle these failures
2. **Provider Schema Access**:
- When API endpoints fail, we attempt to download the provider schema directly
- This provides a complete schema but requires additional processing
## Fallback Strategies
When API endpoints fail, we employ these fallback strategies:
1. **Documentation URL Parsing**:
- For resource details, we fall back to using the documentation URL directly
- URLs follow the pattern: `https://registry.terraform.io/providers/{namespace}/{provider}/latest/docs/resources/{resource}`
2. **Provider Schema Download**:
- For resource details, we can download the complete provider schema
- This requires additional filtering to find the specific resource
## Future Improvements
Potential improvements to our API interaction:
1. **Retry Logic**: Add more sophisticated retry logic for transient failures
2. **Version Selection**: Allow users to specify provider versions for more precise documentation
