Lucid's official remote MCP server lets AI tools search, read, summarize and edit Lucidchart and Lucidspark documents, create diagrams and export them as images. It uses OAuth by default, with API keys for unattended use on Team and Enterprise plans, and also offers read-only and repositories-only endpoints. Team and Enterprise admins must enable MCP access first.
