FlowchartAI MCPData VisualizationFlowchartAI MCP connects AI assistants to editable flowcharts. Generate diagrams from text or an image, revise an existing diagram with natural-language instructions, list and read saved diagrams, inspect task and version history, and export editable draw.io XML or JSON. Saved diagrams open in the FlowchartAI web editor for further editing and PNG/SVG rendering. The hosted Streamable HTTP endpoint supports OAuth with PKCE and scoped API keys. Generation and edits use the existing account allowance or Credits, with per-task spending caps and account/key budgets. The public repository is MIT licensed; the hosted service requires a FlowchartAI account.51GoodAuth: oauth 2.0Verdict: choose FlowchartAI MCP for data visualization work; choose Agentic Mermaid for data visualization as a local process.
