What formats can I export flowcharts in?

FlowchartAI exports editable draw.io XML or JSON, and saved diagrams can be rendered as PNG or SVG through the web editor. The XML format is fully compatible with draw.io for further editing.

How do I authenticate and set up the MCP server?

The hosted endpoint at https://flowchartai.org/api/mcp uses OAuth with PKCE and scoped API keys. You'll need a FlowchartAI account; authentication details and key setup are managed through your account dashboard.

What are the costs and spending limits?

Generation and edits consume your account allowance or Credits. You can set per-task spending caps and configure account-level or API-key-level budgets to control costs.

Can I generate flowcharts from images?

Yes, FlowchartAI can generate diagrams from both text descriptions and images, making it easy to convert sketches or existing diagrams into editable flowcharts.

Is there a self-hosted or open-source option?

The public repository is MIT licensed, so you can self-host or modify the code. The hosted service at flowchartai.org requires a FlowchartAI account and uses the web editor for viewing and rendering.
