Diagram

How to Set Up and Use Diagram

The Infrastructure Diagram MCP Server is a Python-based tool that lets AI assistants generate architecture diagrams for AWS, Azure, GCP, Kubernetes, and other cloud platforms using the Diagrams-as-code library, which provides over 2000 icons. It exposes three parsing tools that accept Kubernetes manifests, Helm charts, and Terraform HCL files — extracting resources and relationships automatically — and then renders them as PNG diagrams or .drawio files ready for editing in draw.io. Developers and infrastructure engineers use it to visualize cloud architectures, document IaC configurations, and share diagrams without manually maintaining diagram tools.

# macOS:
brew install graphviz

# Ubuntu/Debian:
sudo apt-get install graphviz graphviz-dev

# Windows:
choco install graphviz

# macOS example (adjust path from 'brew --prefix graphviz'):
export CFLAGS="-I$(brew --prefix graphviz)/include"
export LDFLAGS="-L$(brew --prefix graphviz)/lib"

# Ubuntu/Debian: usually not needed, headers are in standard paths

# macOS:
brew install helm

# Linux:
curl https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 | bash
