Overview
Lucid MCP Server is a Model Context Protocol server designed for Lucid App integration. It enables multimodal LLMs to access and analyze Lucid diagrams by exporting visual content and metadata to the MCP environment. The server supports document discovery and retrieval of metadata from LucidChart, LucidSpark, and LucidScale, plus lightweight tab metadata for quick document structure overview. It can export PNG images of diagrams for rendering and offline analysis. For AI-powered analysis, it supports both Azure OpenAI and OpenAI providers, with environment-based API key management and automatic fallback from Azure to OpenAI when configured. The implementation is TypeScript-based with full test coverage and includes MCP Inspector integration for easy testing. Prerequisites include Node.js v18+, a Lucid API Key, and optional AI provider keys (Azure OpenAI or OpenAI). Quick Start covers installation, configuration via environment variables, and verification using the MCP Inspector. The server is designed to work within the MCP ecosystem to simplify multimodal AI workflows around Lucid diagrams.
