Automatically turn Terraform code into professional cloud architecture diagrams.

The supplied materials identify TerraVision as an AGPL-3.0 open-source, locally run Terraform diagram generator with stdio MCP startup support. It offers full AWS coverage and core-service support for Azure and GCP, but the materials do not provide MCP tool names or client compatibility information.
TerraVision is a locally run MCP server that generates cloud architecture diagrams from Terraform code or pre-generated Terraform plans. It supports AWS, Google Cloud, and Azure, uses official cloud-service icon sets, and can produce interactive HTML, PNG, SVG, PDF, and editable draw.io outputs.
Tools
The tool list has not been reviewed yet.
Setup
Start it with uvx: uvx --from terravision[mcp] terravision mcp. The environment requires Python 3.10+; normal Terraform processing also requires Terraform 1.x, Graphviz, and Git.
Fit and risk
Not for
- Projects that do not use Terraform
- Workloads requiring complete Azure or GCP resource coverage
- Users seeking server-side cloud discovery or remote infrastructure management
Required permissions
- It needs to read local Terraform projects, variable files, and optionally plan JSON and graph DOT files
- Normal operation requires local Terraform, Graphviz, and Git installations
- AWS credentials are needed when using AWS Bedrock for AI annotations
Risks and side effects
- Azure and GCP currently have partial support limited to core services, so diagrams may be incomplete
- When Bedrock or another REST API annotation backend is enabled, metadata and a summary graph are sent to the configured model service; the README states that .tf source files are not sent
- Generated diagrams depend on the accuracy of the Terraform, plan, or graph inputs and do not replace infrastructure validation
Troubleshooting
- Confirm that Python 3.10 or newer is installed
- Confirm that Terraform 1.x, Graphviz, and Git are installed and available
- When using a pre-generated plan, provide both the plan JSON and graph DOT files
- Check the Terraform workspace, varfile, and source directory
- For AI annotations, verify the selected backend configuration and AWS credentials or REST API environment variables
Use cases
