Blueprint Mcp

Blueprint MCP generates visual diagrams and flowcharts for understanding codebases and system architecture by leveraging Nano Banana Pro's diagram generation capabilities. The server provides three core tools—`start_diagram_job`, `check_job_status`, and `download_diagram`—that enable asynchronous diagram generation and retrieval as base64 PNG images. It solves the problem of visually documenting complex systems and data flows by integrating with Arcade's ecosystem to extract information from platforms like GitHub, Google Drive, and HubSpot, then converting that data into architecture diagrams, sequence diagrams, and flowcharts.
