@diagrammo/dgmo-cli

The dgmo command — render DGMO diagrams to PNG or SVG from your terminal, and wire the DGMO MCP server into AI editors.

brew install diagrammo/dgmo/dgmo     # macOS
npm install -g @diagrammo/dgmo-cli   # anywhere
npx @diagrammo/dgmo-cli diagram.dgmo # no install

Rendering

dgmo diagram.dgmo                          # PNG (the default)
dgmo diagram.dgmo -o output.svg            # format follows the extension
cat diagram.dgmo | dgmo > out.png          # stdin
dgmo diagram.dgmo --theme dark --palette catppuccin
dgmo share diagram.dgmo                    # shareable link, copied to the clipboard

AI editors

dgmo install                # auto-detects what you have, no prompts
dgmo install claude-code    # or name one

Detects Claude Code, Codex, Claude Desktop, Cursor, Windsurf and Copilot, and points each at the DGMO MCP server. dgmo mcp runs that server directly.

Also

dgmo types          # the chart types, and what each is for
dgmo diagnostics    # every diagnostic code the parser can emit

Which package is which

| Package | What it is | |---|---| | @diagrammo/dgmo-cli | this — the dgmo command | | @diagrammo/dgmo | the library: render(), the parsers, the palettes | | @diagrammo/dgmo-mcp | the MCP server, installed with this package |

The command lived inside @diagrammo/dgmo until 0.61.0. It moved out so that a documentation build calling render() stops installing a command-line program and a native rasterizer it never reaches.
