Render one Mermaid source to durable assets:

npx vaults-mermaid-render path/to/diagram.mmd --output-dir out --manifest out/manifest.json

Generate Mermaid diagrams from source code:

npx vaults-source-diagrams --source-dir src --output-dir diagrams

Run the MCP stdio server:

npx vaults-diagram-mcp

Use one-shot npx when the project should not keep a dependency:

npx --yes --package vaults-diagram-tools vaults-mermaid-render path/to/diagram.mmd --output-dir out
npx --yes --package vaults-diagram-tools vaults-source-diagrams --source-dir src --output-dir diagrams
npx --yes --package vaults-diagram-tools vaults-diagram-mcp
