Mermaid Diagram Generator

Mermaid Diagram Generator for MCP enables AI assistants to create visual diagrams from Mermaid syntax through the Model Control Protocol framework. The implementation provides a server (mcp_server.py) that exposes a diagram generation tool and example resources, along with a client (mcp_client.py) that demonstrates how to interact with the server. Built on FastMCP, it supports multiple themes and background options, handles image data natively, and automatically cleans up temporary files. The server requires Node.js with mermaid-cli installed globally, making it ideal for workflows requiring visualization of relationships, processes, or structures directly within AI conversations.
