The Terraform MCP Server is aModel Context Protocol (MCP)server that provides seamless integration with Terraform Registry APIs, enabling advancedautomation and interaction capabilities for Infrastructure as Code (IaC) development.

• Automating Terraform provider and module discovery
• Extracting and analyzing data from Terraform Registry
• Getting detailed information about provider resources and data sources
• Exploring and understanding Terraform modules

Caution: The outputs and recommendations provided by the MCP server are generated dynamically and may vary based on the query, model, and the connected MCP server. Users shouldthoroughly review all outputs/recommendations to ensure they align with their organization'ssecurity best practices,cost-efficiency goals, andcompliance requirements before implementation.

1. To run the server in a container, you will need to haveDocker installed.
2. Once Docker is installed, you will need to ensure Docker is running.

Add the following JSON block to your User Settings (JSON) file in VS Code. You can do this by pressingCtrl + Shift + P and typingPreferences: Open User Settings (JSON).

More about using MCP server tools in VS Code'sagent mode documentation.

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

Optionally, you can add a similar example (i.e. without the mcp key) to a file called.vscode/mcp.json in your workspace. This will allow you to share the configuration with others.

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

More about using MCP server tools in Claude Desktopuser documentation.

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

The following sets of tools are available:

Use the latest release version:

go install github.com/hashicorp/terraform-mcp-server/cmd/terraform-mcp-server@latest

Use the main branch:

go install github.com/hashicorp/terraform-mcp-server/cmd/terraform-mcp-server@main

{"mcp": {"servers": {"terraform": {"command":"/path/to/terraform-mcp-server","args": ["stdio"]      }    }  }}

Before using the server, you need to build the Docker image locally:

1. Clone the repository:

git clone https://github.com/hashicorp/terraform-mcp-server.gitcd terraform-mcp-server

2. Build the Docker image:

make docker-build

This will create a local Docker image that you can use in the following configuration.

{"servers": {"terraform": {"command":"docker","args": ["run","-i","--rm","terraform-mcp-server"      ]    }  }}

• Go (checkgo.mod file for specific version)
• Docker (optional, for container builds)
