Generates a Mermaid entity relationship diagram from an exported schema JSON file. Creates visual documentation of your data model with tables, columns, and relationships. Perfect for documentation, presentations, and understanding data structure.
AI agents call generate_mermaid_diagram to retrieve information from Dataverse MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads an existing schema JSON file and produces a diagram/visualization. It has no side effects on data, system state, or external services — it purely transforms input data into a visual representation. Misuse potential is minimal.
