FAQ from Diagrammo (dgmo)

How does Diagrammo (dgmo) compare to Mermaid?

dgmo offers beautiful defaults with 10 built-in palettes, supports more diagram types (ER schemas, C4, kanban, infrastructure, tech radar, etc.), generates persistent share links, and requires no API key — all rendering is local.

What dependencies or runtime are required?

The server runs via npx, so Node.js and npm must be installed on your machine. No additional dependencies or accounts are needed.

Where does my diagram data live?

All rendering happens locally on your machine. Your diagram text and data never leave your computer. Share links encode the diagram markup in the URL but are hosted on diagrammo.app.

What transports and authentication does the server use?

The MCP server communicates over standard stdio transport. No API key, authentication, or external services are required for rendering.

Are there any known limits or unsupported features?

The README does not describe any specific limits. All 35+ chart types are fully supported locally. The server provides a get_language_reference tool to fetch full syntax documentation.
